Maximize Efficiency in High Temperature Applications With Boron Nitride Crucibles
High temperature insulation is key to minimizing energy use and optimizing industrial processes efficiently, as well as contributing to reduced greenhouse gas emissions – an integral component of reaching sustainability goals.
Hexagonal boron nitride (h-BN) is an ideal material for handling hot metals, aggressive chemicals and aggressive materials due to its unique chemical stability, thermal performance and electrical insulating properties – making it an invaluable material choice for use in specialized crucibles.
High Thermal Conductivity
Hot-pressed boron nitride (H-BN) crucibles from high purity hot pressing have an impressive thermal conductivity rating of 33 W/mK – the highest among ceramic materials. Under inert gas protection they can withstand temperatures of 2100 degC while 1900 degC can be reached in vacuum conditions.
Hexagonal boron nitride’s non-wetting properties and inability to react with most molten metals make it an ideal material for metal melting and crystal growth applications. Furthermore, its vibration friction tolerance also make it suitable for use as a material in high vibration applications.
Melting of high lead glass glaze at 800-950 degC will erode BN but won’t react under protection of nitrogen or inert gases like inert. Boron phosphate reacts with 1400 degC nitrogen at high concentration or with hot concentration or molten alkali solutions and chlorine gas. As it easily absorbs moisture, boron nitride cannot be stored or washed using water at this temperature range.
Low Coefficient of Thermal Expansion
Boron nitride crucibles offer many advantages when used for applications requiring both high temperatures and chemical stability, including their low coefficient of thermal expansion and self-lubricating surface, which helps minimize cracking or breaking under extreme temperature conditions. They also boast reduced friction during usage by acting as an antifriction mechanism and wear protection mechanism.
hexagonal boron nitride is non-toxic to humans and the environment, making it a safe option when working with dangerous materials like liquid metals or acids.
Note, however, that hexagonal boron ceramics are more delicate than alumina ceramics and should always be handled carefully when working with hot crucibles. Always wear heat-resistant gloves and tongs when moving a hexagonal boron or other ceramic crucible crucible for safe transport.
Excellent Chemical Inertness
Boron Nitride (hBN), unlike oxide ceramics, does not react with metals used in high temperature applications or materials that might contain contaminants – eliminating contamination risk and safeguarding synthesized materials – both vital considerations in industries like metallurgy and semiconductor manufacturing.
hBN also resists wetting from liquid metals and other substances, thus eliminating adhesion issues common with other crucible types. Coupled with its thermal shock resistance and superior electrical insulation properties, these qualities make hBN an excellent material choice for demanding industrial processes that demand extreme chemical stability, non-wetting characteristics, purity of synthesized materials, etc.
Due to these reasons, boron nitride crucibles have become essential tools in high-temperature applications. Shop boron nitride smelting crucibles today to optimize process efficiency and quality – we offer various shapes and sizes to meet all of your unique requirements!
Moldability
Contrasting with graphite’s non-polar, homonuclear C-C intra-layer bonds, hexagonal boron nitride (h-BN) features polar B-N bonds for unique characteristics that benefit crucible applications.
Hexagonal boron nitride boasts excellent chemical inertness, meaning that even at extremely high temperatures it won’t react with liquid metals or other substances – an invaluable property when creating complex alloys and compounds with specific functions.
Boron nitride ceramics excel at handling highly reactive and corrosive materials in demanding industries like aerospace and transportation, with precise temperature management to prevent damage to crucibles ensuring workers’ safety while also increasing product life span and decreasing maintenance costs.
Corrosion Resistance
Boron Nitride Crucibles are extremely resistant to corrosion from different materials when used in high temperature applications, including acids and alkalis used for manufacturing advanced alloys or synthesizing specialized materials. When properly cared for they will remain functional even over a long period of time.
Hexagonal boron nitride (BN) is the ideal material for high temperature applications due to its ability to hold nonferrous and ferrous metals as well as ceramic materials securely without reacting with oxygen, making it suitable for wafer processing equipment and materials research applications. Additionally, this versatile material melts rare earth materials, glass and molten salt without reacting with oxygen – an indispensable feature for sensitive applications like wafer processing equipment and materials research.
Boron nitride crucibles offer superior thermal stability, low thermal expansion coefficient and chemical inertness – qualities which contribute to their long service lives and reduced maintenance and replacement costs as well as more consistent process results.
