Ceramic products based on boron nitride (BN)
One of the key characteristics of boron nitride is that it provides to any item more thermal resistance, density and stability. Boron nitride is widely used in heavy industry and for chemicals.
Boron nitride ceramics was widely adopted in aircraft and rocket engineering, machinery and glass melting, chemical industry, energy and metallurgy. Production of high temperature hardware often involves crucibles, insulators and electric vacuum tools of boron nitride.
A unique combination of thermal, physical and chemical characteristics of boron nitride ceramics make it perfect to meet complex needs and tackle the entire range of production challenges.
Characteristics:
- Thermal capacity
- Non-toxic
- Chemical inertness
- High dielectric strength
- Low dielectric capacity
We supply heat resistive ceramics based on hexagonal boron nitride (of different shapes and dimensions per Customer’s needs and requirements).
Application:
- Crucibles, insulators and high temperature ceramics;
- High temperature lubricants;
- Synthesis of extra-soil substances;
- Production of electric vacuum hardware and semiconductors.
