Maximize Thermal Stability With a Boron Nitride Crucible
Boron Nitride (BN) crucibles are ideal for high-temperature applications because of their purity and chemical resistance. Additionally, these crucibles are frequently utilized in Physical Vapor Deposition and Chemical Vapor Deposition processes.
Temperature in air should not go beyond 900 degrees or the coating may oxidize and fail. Therefore, it’s advised to store it in a dry area and forgo washing; direct wiping with sandpaper or alcohol-scrubbing are viable solutions.
Exceptional Thermal Stability
hexagonal boron nitride stands out among materials as one of only a handful that exhibit exceptional thermal stability at high temperatures, making it suitable for semiconductor manufacturing and metal melting applications as well as providing electrical insulation, corrosion resistance and low coefficient of friction. As such, hexagonal boron nitride makes an excellent material choice.
Boron Nitride Crucibles are ideal for demanding applications that demand superior chemical inertness and purity, such as handling highly reactive materials like liquid metals. Furthermore, these BN crucibles can operate in an oxidative environment without producing oxides; something essential when working with highly reactive materials like liquid metals. In addition, these devices are capable of withstanding high temperatures for rapid cooling purposes, taking in air several hundred times without cracking open.
Low Thermal Expansion Rate
Boron nitride stands out among other crucible materials due to its extremely low coefficient of thermal expansion, meaning it doesn’t experience significant dimensional changes when exposed to extreme temperature fluctuations, decreasing risk of cracking and failure.
Boron nitride’s chemical inertness makes it an attractive material choice, since many metals and salts can damage alumina crucibles with corrosion or contamination, but this does not occur with boron nitride, allowing faster turnaround and higher quality final products.
Conductive boron nitride crucibles are ideal for alloy melting, rare earth and ceramic sintering and electron beam evaporation coating applications. Their heat tolerance and low wettability help speed material changes over time while their low thermal expansion rate helps extend service life of these durable vessels.
Chemically Stable
PBN crucibles are well known for being thermally stable and chemically inert, making them the ideal material for processes requiring high levels of precision and cleanliness. Furthermore, this type of material will not react with many materials used in daily life – such as acids, bases, or liquid metals – making them suitable for safe usage across a wide variety of processes and uses.
Boron nitride crucibles differ significantly from their alumina counterparts in that they do not erode at higher temperatures and compromise the final product; its low wettability prevents bonding between it and molten salts or metal oxides, keeping your product intact and free from contamination.
Boron nitride must be stored under an inert gas like nitrogen or argon to avoid moisture build-up on its surface and maintain good condition for years to come. This precautionary step ensures it remains in top shape!
Extremely Tough
hexagonal boron nitride (hBN), unlike graphite which can crack when exposed to sudden fluctuations in temperature, resists thermal shock. As such it makes an excellent material for crafting high-temperature processes crucibles.
Hexagonal boron nitride is soft enough to be machined into almost any custom shape, giving you the ability to design a crucible that perfectly meets the specifications of your particular process.
hBN ceramic is resistant to corrosion from many liquid metals, making it an excellent choice for melting and holding molten copper alloys, titanium alloys, nickel and aluminum as well as waste materials from smelting or casting operations. Furthermore, its high temperatures capabilities and oxygen-sensitive melting processes makes hBN an excellent alternative to yttrium oxide ceramics in certain applications.
Suitable for a Wide Range of Applications
Boron nitride is highly versatile material that is machined and formed into various shapes for easy application in various fields. Chemically inert and resistant to oxidation, boron nitride also reacts with few substances making it suitable for processes that prioritize purity of material being processed.
As it’s highly durable, it can withstand even extreme environments like high temperatures and chemical corrosion – perfect for industries such as semiconductor manufacturing, materials research and more.
Boron nitride crucibles offer superior performance over graphite when used at high operating temperatures, as they will not erode at such temperatures nor react with liquid aluminum, zinc, glass melts, silicates and high lead glass glaze. Due to these superior characteristics BN crucibles are frequently employed for metal smelting and ceramic melting applications.
