Superior Heat Resistance With Boron Nitride Crucible
Hexagonal boron nitride crucibles are an ideal choice for applications requiring high temperature resistance and chemical stability, including corrosion-resistance against liquid metals as well as excellent electrical insulation properties. Furthermore, their hexagonal shape offers corrosion-resistant protection from erosion when working in hot environments while their electrical insulation properties make them an excellent option.
They are non-wetting to molten metals and microwave transparent, unlike many ceramic materials, enabling precise temperature profiling during operations such as crystal growth or materials synthesis.
High Temperature Resistance
Boron nitride outshines graphite by boasting superior high-temperature resistance and can withstand temperatures that far surpass graphite without suffering structural changes, making BN crucibles ideal for applications such as crystal growth and metal melting, which require extreme high heat temperatures.
Boron nitride’s non-wetting properties help protect molten metal from reacting with its environment and decreases thermal stress during the melt process, protecting it from contamination while decreasing thermal stress levels during its melt process.
Boron nitride ceramics are extremely stable, and can even be used under protective gas to increase their maximum working temperature (up to 2100 degC). Since boron nitride is an oxygen sensitive material, it should be stored away from humidity and washed only with alcohol or fine sandpaper to avoid oxidation. Please be aware that consumable items like boron nitride crucibles are not covered under warranty and please reach out for more details.
Corrosion Resistance
Boron Nitride (hexagonal boron nitride or h-BN) offers many advantages over graphite and other carbon-based materials for high temperature applications, especially those involving wear and corrosion resistance. Due to its multilayered microstructure design, h-BN makes an excellent material choice for melting metals such as aluminium, glass and halide salts while melting ceramics and semiconductor material processing processes.
H-BN stands out among other refractory materials due to its inertness toward chemicals at higher temperatures, making it ideal for jewelry production, precious metal smelting and nanomaterial synthesis processes. H-BN helps ensure material integrity while simultaneously increasing manufacturing process efficiency by limiting unwanted chemical reactions.
Solid boron nitride offers superior moisture resistance, making it essential in environments with high humidity or condensation levels. Grade AX05 of solid boron nitride also boasts non-reactivity against most molten materials and halide salts, making it suitable as a non-reactive crucible or feed-through component due to its advanced production technique and purity.
Low Friction Coefficient
Boron Nitride is highly durable and can withstand high temperatures without degrading, making it the ideal material for use as a crucible in experiments that involve melting metals or ceramics, while its neutron-absorbing properties also make it useful in nuclear industries for handling radioactive materials. Furthermore, boron nitride crucibles are often employed in inert environments due to its chemical inertness as it won’t react with many substances such as liquid salts.
Hexagonal Boron Nitride (H-BN) can be easily machined when in its hot pressed state, enabling precision molding of different shapes and sizes. Furthermore, H-BN features self-lubricating properties which help it endure extreme conditions without becoming damaged.
H-BN boasts low thermal expansion and resistance to temperature shock, making it the perfect material for applications requiring precise temperature profiles such as crystal growth and materials synthesis. Furthermore, its non-wetting and microwave transparency properties help avoid chemical reactions which could otherwise occur.
High Purity
Boron Nitride crucibles are highly malleable, enabling manufacturers to customize the shapes of their crucibles for specific applications. Furthermore, they are chemically inert – meaning they won’t interact with molten metals or materials used in high temperature processes that could potentially contaminate and compromise materials being processed, an essential feature in industries like electronics and metallurgy.
These boron nitride ceramic crucibles are produced through a thermal purification process that involves heating raw BN to 2,000 degrees Celsius under inert atmosphere, then cooling to remove all impurities and contaminants – leaving behind only pure material suitable for use in demanding environments.
Hexagonal Boron Nitride (h-BN) is an advanced synthetic ceramic designed for various demanding applications. It boasts excellent thermal conductivity and low wettability to molten metals and glass while offering good lubricity and exceptional chemical resistance in harsh environments. Furthermore, this material can easily be machined while having very low thermal cycling behavior in use.
