Boron Nitride Crucibles

Boron nitride crucible is made of high-purity and high-quality boron nitride as raw material, using the internationally advanced vacuum hot-pressing sintering technology, pressed into blocks, and processed according to the size and specifications required by the user. It is suitable for melting aluminum, zinc and other alloys, replacing graphite crucibles.

 

The crucible does not crystallize under high temperature conditions and is pollution-free, ensuring the purity of smelting metals. It has strong thermal shock resistance and does not crack after being quenched after being heated to 1500 degrees. It can be kept warm in a furnace at 1000 degrees for 20 minutes and can be repeatedly quenched by blowing for hundreds of times without cracking. Thermal conductivity is similar to stainless steel. It has stable chemical properties, is resistant to acid and alkali corrosion, and is resistant to molten metal. And glass corrosion, does not react to molten metals such as copper (Cu), stainless steel, iron (Fe), tin (Sn), zinc (Zn), lead (Sb); its mechanical properties are higher than graphite, and there is no softening phenomenon under high temperature load; It has good insulation performance and its electric shock intensity is 4 times that of aluminum oxide.
