Pyrolytic Boron Nitride (PBN) crucibles are ultra-high purity ceramic containers manufactured by chemical vapor deposition (CVD), achieving purity levels exceeding 99.99% with exceptional thermal stability up to 2000°C in inert atmospheres. Unlike conventional sintered ceramics, PBN exhibits anisotropic thermal conductivity, excellent thermal shock resistance, and non-wetting properties against molten metals and semiconductors. These crucibles are indispensable for Molecular Beam Epitaxy (MBE) systems, compound semiconductor crystal growth (GaAs, InP, GaN), and high-temperature evaporation processes. Innovacera's PBN crucibles are engineered with precise wall thickness control and customizable geometries, ensuring contamination-free environments for the most demanding semiconductor manufacturing applications.
