Hot-pressed Boron Nitride Crucibles

Hot-pressed Boron Nitride Crucibles are high-performance ceramic components made from hexagonal boron nitride through a hot-pressing sintering process. Hot pressing sintering process promotes the close arrangement of boron nitride particles under high temperature and high pressure, forming a structurally stable dense body. This effectively reduces internal porosity and defects while also significantly improves crucibles' mechanical strength. Simultaneously, boron nitride crucibles prepared by this process possess excellent chemical stability and corrosion resistance and do not react with most molten metals. This property effectively avoids crucible performance degradation caused by melt contamination, making it particularly suitable for smelting reactive metals such as aluminum and magnesium.

Since crucibles need to undergo rapid heating and cooling within high-temperature furnaces, their materials is required to maintain their original structure under the shock of sudden temperature fluctuations. Hot-pressed boron nitride ceramics possess excellent thermal stability, enabling them to withstand sudden temperature changes and remain stable at high temperatures. This characteristic significantly lowers the risk of cracking, warping, or thermal deformation, thereby extending the crucible's lifespan. Therefore, choosing Semicorex's Hot-pressed Boron Nitride Crucibles not only reduces downtime and procurement costs caused by frequent crucible replacements but also creates cost advantages and empowers production efficiency upgrades for enterprises by improving production continuity and equipment utilization.

Hot-pressed Boron Nitride Crucibles are typically installed in the core heating areas of high-temperature furnaces to support and melt materials in the demanding high-temperature conditions. Thanks to their excellent thermal stability, low coefficient of thermal expansion, superior corrosion resistance, and exceptional mechanical strength, Hot-pressed Boron Nitride Crucibles are widely used in the following fields:

1. Metal smelting and processing;

2. The growth of compound semiconductor crystals such as GaAs and GaP

3. Processing of optical glass and optical components.
