Application of Alumina Tubes

At present, the electric contacts on high pressure or ultra high pressure boilers are made of ultra pure alumina porcelain tubes as insulators. Because alumina tube has very high mechanical strength and excellent insulation performance, but also has a strong high temperature acid and alkali corrosion resistance, used for high pressure and ultra-high pressure boiler furnace water quality is good, the life can reach more than

At present, the electric contacts on high pressure or ultra high pressure boilers are made of ultra pure alumina porcelain tubes as insulators. Because alumina tube has very high mechanical strength and excellent insulation performance, but also has a strong high temperature acid and alkali corrosion resistance, used for high pressure and ultra-high pressure boiler furnace water quality is good, the life can reach more than one year.

In addition, the thermal shock resistance of the ultra-pure alumina porcelain tube is poor, which is easy to cause the insulator and porcelain sealing parts to leak due to damage. Therefore, in use, the electrical contact should be preheated as slowly as possible to prevent the motor from being damaged by steam flow impact and sudden temperature change.

We know that most high-pressure sodium lamps are made of alumina tubes, and the luminous flux of high-pressure sodium bulbs is closely related to the specific properties of alumina tubes.
Relevant factors include:
1.The light transmittance of alumina tube is related to the level, the alumina tube in use are polycrystalline alumina tube, the light transmittance is about 92%~93%, if the use of single crystal alumina tube its light transmittance can reach about 97%, but its performance is brittle, vibration resistance.
2. Air pressure in alumina tube.
3. Production process.
4. The emission performance of the electrode, that is, the overflow power should be low.

At present, high pressure sodium lamp is widely used to replace high pressure mercury vapor lamp, which not only increases the light flux but also saves the power loss, so it has a good development prospect.

Boron Nitride for Molten Glasses Application

Boron nitride, also known as white graphite, has a structure similar to that of graphite. It has good electrical insulation, thermal conductivity, excellent thermal shock resistance and Chemical stability.

BN-sintered parts are generally produced by hot-pressing sintering. The densification mechanism can be described as vitreous sintering. Small amounts of boron oxide (B2O3) function as the liquid phase during sintering and as a binder for the BN platelets. In contrast to some other non-oxide ceramics, there is no solution and precipitation process known for the sintering of BN.

Boron Nitride for the application of glass:
1.Glass Melting – BN crucible
2.Glass Spinning – BN mould (Similar as nozzle. Glass go through it and turn to a
wire)
3.Glass Forming – BN plate

Why Boron Nitride can be used for glass melting?
Boron Nitride ceramic is with good self-lubrication. So glass won’t be stick to Boron Nitride. Also, Boron Nitride is without corrosion during workin.

Hexagonal boron nitride, either in its pure form or as a composite, is an extremely suitable material for special applications at high temperatures. Parts for high-temperature furnaces, crucibles for molten glasses and metals, side dams for thin-strip casting and evaporation boats for aluminium are the most common applications.

About Zirconia Partially Stabilized Zirconia Ceramics (Mg-PSZ)

Introduction：Magnesium oxide partially stabilized zirconia with magnesium oxide (MgO) as the stabilizer of zirconia, after forming the crystal structure for a cube, more stable. Magnesium zirconium has better resistance to high temperature and moisture because it is not affected by phase migration.

What is magnesium oxide partially stabilized zirconia ceramics

The oxidase-partially stable zirconia ceramics (MG-PSZ), which is commonly referred to as magnesium-zirconia ceramics, are all yellow with a density of about 5.7g/cm³.

Magnesium oxide partially stabilized zirconia with magnesium oxide (MgO) as the stabilizer of zirconia, after forming the crystal structure for a cube, more stable. Magnesium zirconium has better resistance to high temperature and moisture because it is not affected by phase migration. Magnesium zirconium retains its strength even in humid, high temperature environments where the mechanical properties of yttrium partially stabilized zirconia begin to deteriorate.2. Advantages and disadvantages of magnesium stabilized zirconia ceramics

Advantages and disadvantages of magnesium stabilized zirconia ceramics

Compared with yttrium oxide, magnesium oxide partially stabilized zirconia has the outstanding advantages of excellent mechanical properties and creep resistance at relatively high temperatures. However, the research and development of magnesium stabilized zirconia is restricted by two adverse factors: one is that the solution temperature of magnesium oxide in the cubic zone of zirconia is very high, resulting in magnesium stabilized zirconia is not easy to completely sintering; First, when zirconia is higher than 1000℃, magnesium oxide is easy to produce crystal phase separation and a large number of tetragonal phase instability, which makes the material properties decline and seriously restricts its application in high temperature region.

LaB6 Ceramics Parts

LaB6 ceramic is an inorganic compound classified as a boride. This refractory ceramic material boasts a distinctive deep purple appearance and possesses an impressively high melting point of 2210°C. Additionally, it exhibits insolubility in both water and hydrochloric acid. Interestingly, when subjected to ion bombardment, its physical characteristics undergo a change, resulting in a green coloration instead of its typical dark purple hue.

The unique properties of LaB6 crystals make them exceptionally suited for use as stable electron-emitting media with work functions close to 2.70 eV. This low work function leads to the generation of higher electron currents at lower cathode temperatures compared to tungsten, resulting in greater brightness at the beam focus and an extended operational lifespan. In practice, LaB6 cathodes often demonstrate brightness levels ten times higher and a service life fifty times longer than tungsten cathodes. In electron microscopy applications, these advantages translate into the delivery of more precise beam currents focused on smaller sample areas, improved resolution, and reduced frequency of cathode replacement.

LaB6 ceramic finds wide-ranging applications, including:

1. Thermionic emission (cathode)
2. Applied in scanning electron microscopes
3. Utilized in surface analysis equipment
4. Serving as a plasma source for plasma-enhanced coating (PECVD)
5. Utilized in transmission electron microscopes
6. Used in radiotherapy devices
7. Utilization in vacuum electron beam welding machines
8. Implementation in devices for electron beam surface reforming
9. Employed in electron beam lithography devices
