Boron nitride (BN) is an excellent performance and has great development potential The new ceramic materials, including 5 isomers, are hexagonal boron nitride(h-BN), cubic boron nitride (c-BN), wurtzite boron nitride (w-BN), rhombohedral boron nitride (r-BN), and orthorhombic boron nitride (0-BN).Widely used in machinery, metallurgy, chemical industry, electronics, nuclear energy and aviation sky field.
Boron nitride is a crystal composed of nitrogen atoms and boron atoms, the molecular formula is BN, molecular weight 24.81. The chemical composition is 43.6% boron and 56.4% nitrogen.The theoretical density is 2.27q/cm3.
BN powder has the properties of looseness, lubrication, light weight, and easy moisture absorption.The color is clean and white. The product is ivory white.Current research on BN mainly focuses on its hexagonal phase (H-BN)
and studies on the cubic phase (C-BN).

We can customize crucibles with different shapes and sizes according to requirements
Main properties of PBN ceramic
1. High purity (>99.999%), Good gas tightness
2. High density (Can be up to 2.19 g/cm')
3. No gas impurities releasing at high temperature
4. Excellent thermal shock resistance
5. Long service life time
Typical applications of PBN ceramic
Boron nitride can be used to manufacture crucibles for melting semiconductors and high-temperature containers for metallurgy, amorphous strip nozzles, semiconductor heat dissipation insulation parts, high-temperature bearings, thermocouple casings, and glass forming molds, etc.
