Thick film metalizing ceramic parts

Xiamen Innovacera Advanced Materials Co., Ltd can provide thick film metalizing ceramics.

The ceramic parts do metalized coating or plating. Thick film coatings include Molybdenum-Manganese (Mo-Mn) providing excellent adhesion to ceramic parts. This can be followed by a barrier diffusion layer of electrolytic pure Nickel (Ni). The third layer of gold (Au) or other precious metal, results in a tightly sealed ceramic to metal assembly ready for the soldering or brazing process.

MCH Heater

The MCH Heater is called Metal Ceramic Heater.

They are doing by HTCC. The short description is as below:

Painting the high melting point metal(tungsten) paste on to the Al2O3 casting tape in coordinate to the circuit design, then another layer of sintering additives. After that, repeating the process to build multiple layers. Then, they are sintered together under 1600 °C hydrogen gas environment.
Finally, nickel leads are brazed at 800 °C onto the metal end and put on with Teflon sleeve, which make it a MCH heating element.
It is a new type of high efficient heating elements, which can save more than 20%-30% power effect compare to PTC ceramic heaters.
Our alumina ceramic heaters have many excellent features that do not exist in the sheath heaters:
1. High power density, excellent thermal efficiency
2. Rapid heating, non-hotspot temperature distribution
3. High temperature, small size, light weight
4. Excellent insulation (the leakage current is < 0.5 mA under voltage 4500V/1S testing with no breakdown)
5. High reliability, stable resistance, no electric noise Si Good chemical resistance
6. Full compliance with EU RoHS (no lead, cadmium, mercury, hexavalent chromium, PCBS, and other harmful substances)
7. No charge on surface and safe to touch.

The MCH is widely used in all kinds of applications nowadays, such as Fireplace, Pellet Boiler, Electric Iron, Boiler, Electric water heater, Medical machine, Dryer, electric heating splint, Vacuum flask, Electric cooker, capper, UTR cylinder condensation-proofer, Quick food heating, mini thermostatic bath for special crystal parts, automatic exhaust oxidation sensors, industrial equipment heater, and small heating appliance, etc.

Machinable Glass Ceramic is often used for high vacuum insulation

Machinable Glass Ceramic has the advantages of insulation, pore-free, high/low-temperature resistant, acid and alkali resistant.

Machinable Glass Ceramic has a continuous use temperature of 800ºC and a peak temperature of 1000ºC. Its coefficient of thermal expansion readily matches most metals and sealing glasses. It has good machinability and can be lathed, milled, planed, ground, bored, incised and threaded. It also has the advantages of insulation, pore-free, high/low-temperature resistant, acid and alkali resistant and thermal impact resistant.

It is widely used for nuclear, microwave high vacuum insulation, high precision magnetism-free skeleton for aeronautic and astronautic electrical devices, ultra-high voltage insulation for electric motors and structural parts at strong erosion environments. In terms of machinability, it can take place of aluminum oxide and boron nitride ceramics that are difficult to machine.

We can make rod with dimension Ф25mm～Ф160mm, up to 300mm long. And custom shape is ok for us.

Machinable Glass Ceramic

When you need the performance of a technical ceramic and your application requires a ready fabrication of a complicated shape, look to machinable glass ceramic. Machinable glass ceramic can be machined with ordinary carbide tools and requires no firing after machining. No costly delays, no post fabrication shrinkage and no costly tooling to meet specification.

Machinable glass ceramic withstands high temperature 900°C is non-porous/inert, and matches the thermal expansion of most metals. Applications of machinable glass ceramic includes
1. Ultra-High Vacuum Environments
Machinable glass ceramic is used as an insulator or coil support and for vacuum feed-through.In these applications, the conductive materials are supported by the MGC part and a compatible sealing glass is used to produce a vacuum-tight, hermetic seal.
2. Constant Vacuum Applications
Machinable glass ceramic is found in spacers, headers and windows for microwave tube devices and as sample holders in field ion microscopes.
3. Nuclear-Related Experiments
Since MGC is not dimensionally affected by irradiation, small cubes of the material are machined to a tolerance of one micron and used as a reference piece to measure dimensional change in other materials.
4. Welding Nozzles
Welding equipment manufacturers are using MGC as a nozzle on the tips of oxyacetylene torches. The material’s non-wetting characteristic means molten particles won’t adhere to and decrease the effectiveness of the nozzle.

Aluminum Nitride Ceramic

Aluminum nitride (AlN) is a technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties. It has a hexagonal crystal structure and is a covalent bonded material. The use of sintering aids and hot pressing is required to produce a dense technical grade material. The material is stable to very high temperatures in inert atmospheres. In air, surface oxidation begins above 700°C. A layer of aluminum oxide forms which protects the material up to 1370°C. Above this temperature bulk oxidation occurs. Aluminum nitride is stable in hydrogen and carbon dioxide atmospheres up to 980°C. The material dissolves slowly in mineral acids through grain boundary attack, and in strong alkalis through attack on the aluminum nitride grains. The material hydrolyzes slowly in water. Most current applications are in the electronics area where heat removal is important. This material is of interest as a non-toxic alternative to beryllia. Metallization methods are available to allow AlN to be used in place of alumina and BeO for many electronic applications.

Alumina Thermalcouple protection tube

Materials:
By operating temperature, due to variable alumina, it is further divided into 99.5 (corundum), 99 (corundum), 95 (corundum), 85 (alumina porcelain), 75 (mullite porcelain), for materials above, the more the alumina, the higher the operating temperature, the maximum aluminum content vertical use at 1710°C，the minimum aluminum use at 1100°C.

Application:
Mainly used for protection of thermometric elements, to isolate them from outside and reduce or prevent them being corroded, oxidized, or damaged during use.

Stock size of protective tube:
Outer diameter 4mm to 30mm, maximum length 1600mm, wall thickness by dimension scale of product 0.5mm to 4mm.

How to use ?
During use, the thermometric element is insulated well put into the protective tube, and then the open end and the couple ends are sealed with high-temperature clay. When in measurement, the sealed end is inserted into the temperature measuring zone, and it is best to prevent shock cooling or heating from damaging the protective tube during use.

Boron Nitride Solid Parts

A machinable ceramic, Boron Nitride (BN) can be machined into complex parts. After machining, the parts are ready to use without additional heat treatment or firing operations. BN solid parts are mainly used to variously of the super-high temperature of vacuum furnace, metal or glass melting crucible and nozzles. Boron Nitride is most commonly produced as a hot pressed solid which orients during pressing, yielding a hexagonal and platy crystal structure. The resulting material properties are anisotropic, relative to the pressing direction. In fact, the material properties can vary significantly, relative to the direction of pressing and the grade of material.

BOBING-moon cake gambling for Mooncake Festival

In China, Mid-Autumn Festival is also called Mooncake Festival. It is the second largest festival only second to Spring Festival. On every Mid-Autumn Festival, Chinese people will reunite with their families to watch the full moon and eat mooncakes.

In Xiamen of China, there is another special traditional folk custom – Bobing. The playing method of the game is to shake six dices in the red gambling bowl to form the arrangements of “4 red dots”. Different arrangements represent different grades which stand for different “good luck”.

Xiamen Innovacera Advanced Materials Co., Ltd was taken the Bobing Events on Sept.14. All the people enjoyed in this activity. We wish you enjoy the game with your friends and we wish you a happy Mid-Autumn Festival.
