Pyrolytic Graphite Coated PBN Crucible for Electron Beam Evaporation

Pyrolytic graphite coated PBN (pyrolytic boron nitride) crucible refers to a crucible made of PBN material with a coating of pyrolytic graphite on its surface. The purity of Pyrolytic Graphite Coated Crucible is over 99.99% and the air tightness is good, which has high-temperature resistance, chemical stability, good thermal shock resistance, good thermal conductivity, low coefficient of thermal expansion, resistance to acid, alkali, salt, and organic reagent corrosion. In addition, it has a long service life.

By coating a PBN crucible with a layer of pyrolytic graphite, several advantages can be achieved:
1.Enhanced thermal conductivity: The pyrolytic graphite coating improves the thermal conductivity of the PBN crucible, allowing for efficient heat transfer during high-temperature processes.
2.Chemical resistance: The PBN material already exhibits exceptional chemical inertness, and the additional pyrolytic graphite coating further enhances its resistance to corrosive substances, ensuring greater durability and lifespan of the crucible.
3.Non-wetting properties: Pyrolytic graphite has a non-wetting surface, meaning it repels and does not absorb liquids. This property prevents molten materials from sticking to the crucible, facilitating easy removal and preventing contamination.
4.Electrically insulating: PBN itself is an excellent electrical insulator, and the pyrolytic graphite coating maintains the insulating properties of the crucible. This trait is valuable in electrical and electronic applications, where electrical isolation is necessary.
5.Reduced thermal stress: The combination of PBN and pyrolytic graphite helps reduce thermal stress caused by temperature variations, extending the crucible’s lifespan.
Pyrolytic graphite coated PBN crucibles are commonly used in high-temperature applications, such as semiconductor manufacturing, crystal growth, metallurgical processes, and materials research, where both high thermal stability and chemical resistance are critical.

What’s The Differences Between Alumina Ceramic And Zirconia Ceramic

Alumina is a very common technical ceramic material. Zirconia is also widely used in machinery industries. As an advanced ceramics manufacturer, we’d like to introduce the differences between alumina ceramic and zirconia ceramic.

In terms of performance:
1.The density of zirconia ceramics is twice that of alumina ceramics, the bulk density of zirconia is 6.05g/cm3, while that of alumina is only 3.7g/cm3. So zirconia has better compressive properties in comparison.
2.The toughness of zirconia ceramics is 4 times that of alumina ceramics. The toughness of the zirconia ceramic is excellent, which overcomes the inherent brittleness of the ceramic itself, has higher wear resistance, and greatly extends the service life of the product.
3.Zirconia parts with higher surface finish. After grinding and processing of two materials, zirconia has a higher surface finish, and the roughness can reach about Ra0.02. The surface is mirror-like, very smooth, and has a smaller coefficient of friction. But alumina roughness is about Ra0.2~Ra0.4.
4.Zirconia ceramics have excellent thermal insulation, and its thermal conductivity is less than one-tenth of the thermal conductivity of other ceramics.

In terms of price:
The price of alumina is lower than that of zirconia. One of the reasons is the cost of the raw material, another reason is the high processing cost of zirconia ceramics.

In terms of applications:

1.Alumina ceramic could withstand higher temperature, application in industry furnace.
2.As the wear resistance for zirconia is much better, it is frequently used as mortar and pestles, grinding jars and grinding media, bearing balls and ceramic parts in valves and pumps.
3.Zirconia has better corrosion resistance. Zirconia could survive longer in highly corrosive environment and is considered better material in chemistry laboratories.
So Zirconia ceramics are suitable for applications in high-load, high-strength, and chemically corrosive environments, while alumina ceramics are suitable for applications with low loads, high temperatures, and heat dissipation.

Boron Nitride Nozzles for Molten Metal Atomizing

Boron Nitride nozzles are widely used in the processing of metal powder. Molten metal atomization is a process used to fabricate metal powder from a melt. In a typical atomizer, liquid metal is poured from a nozzle into a large chamber while being sprayed with high-pressure water, oil or gas. This causes the metal droplets to separate and condense into a powder that collects at the bottom. Atomization has become one of the most popular methods of powdering metals.

Atomization begins in a furnace where the metal is kept liquefied by electric heating elements. The metal falls into the spray chamber through a “nozzle” – this nozzle is designed to a high degree of perfection and specification. The nozzle is one of the most important parts of the atomization process – a damaged or clogged nozzle can cause the metal flow to stop or the flow to increase dramatically – both of which can disrupt the powdering process.

To prevent this from happening, the nozzle must be mechanically robust and offer no resistance to the flow of liquid metal. At the same time, the nozzle acts as an interface between the hot furnace at the top and the much cooler spray chamber below. Therefore, it needs to be made of a strong refractory material while also being resistant to high-temperature shocks.
Boron nitride has very low thermal expansion. Together with high thermal conductivity, this ensures that the material is very shock-resistant. It can easily withstand rapid changes in the temperature inside the atomizer. It will not crack or crack under thermal stress.
Under high vacuum, boron nitride can withstand high temperatures up to 1800 °C. A gas atmosphere can push the temperature further up to 2100 °C. This means boron nitride will remain solid during the melting of most metals.
It is also easily machinable, allowing us to machine small threads, holes and other finer details with high precision and tolerances. Nozzles made of boron nitride can be easily customized, allowing both constrained and free geometries.

What are the advantages of advanced ceramics produced by cold isostatic pressing

The most commonly used forming processes in the advanced ceramics industry are cold isostatic pressing, injection molding, hot isostatic pressing and dry pressing. As an advanced ceramics manufacturer, we’d like to introduce the cold isostatic pressing process.

CIP is a method of compacting powdered materials into a solid homogeneous mass before machining or sintering. It can produce high-integrity billets or preforms that exhibit little distortion or cracking when fired. Its advantages and features include:

Improve production efficiency: CIP is easy to operate, the process is stable and can be mass-produced, so the production efficiency is high.

Optimizing material properties: CIP can make the powder material form a dense green body under high pressure, which has a high density, usually reaching more than 95% of the theoretical density. This makes the ceramic material produced by cold isostatic pressing have higher strength, hardness and wear resistance.

Fine grains: In the process of CIP, due to plastic deformation and recrystallization under high pressure, a body with fine grains can be obtained, thereby improving the strength and toughness of the material.

Manufacture of complex shaped parts: cold isostatic pressing technology has good adaptability to the manufacture of complex shaped ceramic parts. It can achieve one-time molding of complex shapes through appropriate mold design and pressure control, reducing the complexity and cost of subsequent processing.

Complex shapes: By adopting different mold structures and process parameters, cold isostatic pressing can produce blanks of various complex shapes to meet the needs of different application fields.

Strong controllability: The process parameters of CIP can be precisely controlled, such as pressure, temperature, holding time, etc., so that a green body with specific properties and microstructure can be obtained.

Low material loss: There is no melting during CIP, so there is no chemical reaction and gas phase consumption, and there is almost no material loss.

Energy saving and environmental protection: Since the cold isostatic pressing process does not require high-temperature sintering, it can reduce energy consumption and the amount of waste gas and wastewater discharged.

In summary, this makes the cold isostatic pressing technology has a broad application prospect in the field of ceramic manufacturing.
