Pyrolytic boron nitride ceramics (p-bn)
Boron nitride ceramics is widely used in production of high temperature hardware. One of the key characteristics of boron nitride is that this component provides heat resistance, density and stability to any piece.
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.
Pyrolytic boron nitride is obtained via gas and phase chemical deposition. Compared to standard composition of boron nitride, pyrolytic boron nitride is much purer and has a number of benefits.
Application:
- High vacuum processes (as material for crucibles, baths, tubes and vessels etc.);
- Crystal growing processes (incl., semiconductor crystals);
- Molecular beam epitaxy;
- Special-purpose hardware and electronics (production of integral micro circuits, UHF-energy output displays, etc.);
- Synthesis and growing of semiconductors.
Characteristics:
- High purity (˃99.99%);
- High thermal resistance;
- Chemical inertness;
- High thermal conductivity;
- Radio transparency;
- Non-toxic.
