Advantages of Boron Nitride Crucibles in High-Temperature and High-Purity Applications

By -
Image
Hexagonal boron nitride is an excellent self-lubricating ceramic capable of withstanding extremely high temperatures while maintaining its lubricating properties, even in high-vacuum environments. Boron nitride (BN) crucibles are typically manufactured from hot-pressed boron nitride blanks, ensuring high density and structural integrity. Mechanically, hexagonal boron nitride behaves similarly to graphite, but it offers the additional advantage of outstanding electrical insulation.   Compared with graphite crucibles, BN crucibles exhibit significantly lower risk of carbon contamination and demonstrate greater chemical inertness in many high-temperature processes. In comparison with alumina crucibles, BN crucibles show lower wettability to molten metals, making them especially suitable for applications that demand high purity and minimal interaction between the melt and the container. While different crucible materials are optimized for different process conditions, the appropriate s...

Beyond Light Blocking: Anti-Static Advantages of Black Alumina Ceramics in Optoelectronic Packaging

By -
Image
As optical communication, LiDAR, and high-precision optoelectronic detection systems evolve toward higher power and greater integration density, they place higher demands on the performance of optoelectronic packaging materials. The increase in device power brings challenges in heat dissipation and high-temperature stability, while the improvement in integration density raises the risks of internal stray light interference and electrostatic discharge (ESD), directly affecting system reliability and signal-to-noise ratio. Traditional white alumina has limitations in optical control, and conventional ESD protection solutions often fail to be perfectly compatible with high gas-tightness and high thermal conductivity packaging systems.   Based on the high mechanical strength, thermal conductivity, and excellent insulation properties of black  alumina ceramics , the material achieves a multi-functional integration of optical control, thermal management, and on-chip electrostatic di...

Powder metallurgy has core process advantages such as high material utilization, low unit energy consumption, and environmental protection. It is a technology that is in line with the future direction of carbon neutrality.   In recent years, with the maturity of powder metallurgy technology and the trend of miniaturization of parts, two emerging process routes, metal injection molding (MIM) and 3D printing (AM), have rapidly emerged.   At the same time, the supply of high-quality powder raw materials has begun to become a major factor restricting the development of the industry.   Small and complex parts are undoubtedly more suitable for injection molding and 3D printing (particle size of 20μm or even smaller), and have been increasingly used in high-end fields such as aerospace, medical, electronics, and military industry.   Therefore, the preparation of metal powders with high purity, good sphericity, small particle size and narrow distribution, and low oxygen cont...
