Boron Nitride Crucible With High Heat Resistance
Boron Nitride Crucibles with High Heat Resistance are used in industrial processes requiring handling molten metals and harsh chemicals, being manufactured using boron nitride powder that has been formed into shape through molding and sintered processes.
Hexagonal Boron Nitride (h-BN), with its hexagonal structure similar to graphite, makes for a superior material in crucibles. As it does not react with metals and remains microwave transparent, h-BN makes an ideal material for high temperature operations such as crystal growth and materials synthesis.
Inertness to Molten Metals
Boron nitride crucibles are chemically inert and do not react with any of the metals used during high-temperature processes, thus eliminating contamination. They also feature non-wetting properties and microwave transparency which allow them to hold and melt metals without losing structural integrity.
These crucibles can withstand high temperatures for ceramic melting, silicate melting, metal smelting and crystal growth applications. Furthermore, they can withstand high pressures without cracking under pressure – perfect for storage in dry environments and washing with alcohol or fine sandpaper to avoid moisture absorption and oxidation.
Hexagonal Boron Nitride (H-BN) is more durable than zirconia and can withstand higher temperatures than graphite without altering its structure, making it suitable for applications involving precise temperature profiles such as crystal growth or materials synthesis. Furthermore, due to its excellent thermal stability and low coefficient of expansion it makes an excellent material choice for molten salt electrolysis applications.
Excellent Oxidation Resistance
Boron nitride is an ideal material for metal-smelting crucibles as it resists oxidation at high temperatures while not reacting with the molten materials, thus ensuring purity – an essential factor when working in applications like electronics and metallurgy.
Hexagonal boron nitride also offers excellent corrosion resistance against acidic and alkaline solutions, making for long-term use and maintenance costs. Furthermore, hexagonal boron nitride’s non-wetting nature prevents metals from sticking to it during melting processes, improving overall safety.
Our boron nitride crucibles are constructed from high-purity h-BN ceramic with low impurity content, to ensure optimal performance at extreme temperature ranges. Able to withstand temperatures as high as 2000degC in an inert atmosphere and 1900degC under vacuum conditions, they make ideal tools for thermal analysis applications. For optimal use we advise operating under protective gas environments (Ar/N2); for optimal storage conditions use sandpaper or cloth to remove dirt or residue build-up.
High Thermal Conductivity
Boron nitride boasts superior thermal shock resistance, making it suitable for demanding high-temperature applications. It can withstand sudden temperature changes without cracking or breaking, protecting its purity while ensuring materials processed through it remain pure.
Material used for high-temperature processes generally does not react with liquid metals, ceramics or other common components used during processes; its inertness helps prevent oxidation and contamination while protecting crucible integrity.
Boron nitride can absorb moisture, so it should not be stored or washed with water directly. Wiping with sandpaper or alcohol may be sufficient. Also, temperatures above 900 degrees Celsius should be avoided to prevent its contact surface being oxidized and peeled off – an especially important precaution in environments that involve materials synthesis or crystal growth.
Sturdy Construction
Hexagonal Boron Nitride (h-BN) is an advanced synthetic ceramic designed for demanding applications. Boasting superior high temperature resistance that exceeds even graphite’s capabilities, h-BN makes an excellent choice for metal melting, crystal growth and nanomaterial synthesis processes as it doesn’t wick molten metals and glasses away, is microwave transparent and highly machinable – all characteristics essential in demanding situations.
Boron nitride’s combination of thermal stability, chemical inertness and good lubricity make it an ideal material for high-performance containers such as crucibles – essential components in industrial processes that involve handling liquid metals or aggressive chemicals.
This high-temperature boron nitride crucible features the purest grades of boron nitride (hBN, RBN and C-BN), with excellent chemical resistance properties and heat-resistance; its RBN/c-BN composition making it highly machinable while packaged securely within sealed bags for safe shipping and foam protection to guarantee its quality during transit.
