Honesty Quality Cubic Boron Nitride Ceramic Crucible for Melting Gold
Factory Price Honesty Quality Cubic Boron Nitride Ceramic Crucible for Melting Gold
Boron Nitride (BN) is a white, low porosity refractory material with physical and mechanical properties similar to Graphite. However, unlike Graphite, Boron Nitride has high thermal conductivity and good thermal shock performance. The most common formulation of Boron Nitride contains boric oxide, which can cause Boron Nitride to absorb moisture, resulting in swelling and property degradation.
It is produced in a hot pressed form and the resulting material properties are anisotropic relative to the press direction. In fact, the material properties can vary considerably depending on the direction or the grade of the material. Futhermore, it is easily machined into complex shapes using standard carbide tooling. The operation temperatures range from 900°C for oxidizing environments to 2200°C for inert environments
