Boron Nitride Crucible Descriptions
Boron Nitride Crucible is a premium ceramic crucible engineered for extreme high-temperature melting and handling applications. Fabricated from high-purity hexagonal boron nitride (hBN), this crucible provides exceptional thermal stability up to 1800°C in inert or vacuum environments, along with outstanding resistance to thermal shock. Its inherent non-wetting property prevents molten metals (such as aluminum, zinc, copper, and gold), glasses, and salts from adhering to the inner surface, ensuring clean and easy release of the solidified material. The crucible is chemically inert to most corrosives, slags, and molten materials, and serves as an excellent electrical insulator. Unlike conventional graphite or oxide crucibles, Boron Nitride Crucible does not outgas, oxidize easily, or introduce contamination, making it ideal for high-purity processes including semiconductor crystal growth, non-ferrous metal melting, glass fusing, and advanced laboratory research. Available in various standard and custom sizes, it can be precisely machined to meet specific depth, diameter, and wall thickness requirements.
Boron Nitride Crucible Advantages
- Excellent Thermal Shock Resistance – Survives rapid temperature changes without cracking or spalling.
- Non-Wetting Properties – Molten metals (e.g., aluminum, zinc, copper, gold) and glasses do not stick to the inner surface, ensuring clean release.
- Chemical Inertness – Resists corrosion from most molten metals, slags, acids, and salts.
- No Outgassing / High Purity – Does not release volatile contaminants, making it safe for semiconductor and high-purity processes.
- Excellent Electrical Insulation – Provides high dielectric strength, suitable for induction melting and plasma applications.
- Easy Machinability – Can be machined into custom shapes, sizes, and wall thicknesses using standard carbide tools.
- Low Thermal Conductivity – Provides better thermal insulation compared to graphite crucibles.
- Long Service Life – Outlasts graphite, quartz, and traditional ceramic crucibles in aggressive molten metal environments.
- Non-Contaminating – Does not react with or introduce impurities into sensitive materials like high-purity metals or compound semiconductors.
Boron Nitride Crucible Applications
- Semiconductor Crystal Growth – Used for melting and pulling compound semiconductors like GaAs, InP, and CdZnTe without contamination.
- High-Purity Metal Melting – Melts precious metals (gold, silver, platinum) and reactive metals (aluminum, titanium) in inert atmospheres.
- Glass Melting and Fusing – Handles specialty glasses, solder glasses, and glass-ceramics without sticking or reacting.
- Non-Ferrous Metal Casting – Melts and holds aluminum, zinc, magnesium, and copper alloys for small-scale or laboratory casting.
- Salt and Flux Melting – Contains molten salts, fluxes, and slags in metallurgical or chemical processes.
- Laboratory Research – Used in high-temperature experiments for material synthesis, thermal analysis, and crystal growth.
- Induction Melting – Serves as a crucible in induction furnaces due to its excellent electrical insulation properties.
- Nuclear Materials Processing – Handles radioactive or reactive materials requiring chemical inertness and high purity.
- Superalloy Development – Melts nickel and cobalt-based superalloys without crucible interaction or contamination.
- Optical Material Processing – Melts optical glasses, fluoride crystals, and infrared materials for precision optics manufacturing.
Boron Nitride Crucible Packaging
Boron Nitride Crucible products are typically packaged in vacuum-sealed bags to prevent moisture or contamination, and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.

FAQ
What is a Boron Nitride Crucible used for?
A Boron Nitride Crucible is used for melting and holding high-temperature materials such as metals, glasses, salts, and semiconductors without contamination or sticking.
What temperature can a Boron Nitride Crucible withstand?
A Boron Nitride Crucible can withstand continuous operation up to 1800°C in inert or vacuum atmospheres, and up to 850°C in oxidizing environments.
Does a Boron Nitride Crucible stick to molten metal?
No, a Boron Nitride Crucible has natural non-wetting properties, so molten metals like aluminum, zinc, copper, and gold do not adhere to its inner surface.
Is a Boron Nitride Crucible better than graphite?
A Boron Nitride Crucible is better than graphite for high-purity applications because it does not outgas, resists oxidation, offers electrical insulation, and prevents sticking to molten metals.
What industries commonly use Boron Nitride Crucibles?
Boron Nitride Crucibles are widely used in semiconductor manufacturing, aerospace, precious metal refining, glass processing, laboratory research, and non-ferrous metal casting industries.
