Pyrolytic boron nitride crucibles are traditionally used to vaporize a variety of materials including Gallium (Ga) and Aluminium (Al) for epitaxial growth compound semiconductors due to their high purity, anisotropic thermal properties, chemical inertness, thermal stability, and thermal shock resistance.Nextgen Advanced Materials supplies Pyrolytic boron nitride crucible with high quality and fast delivery. Customization is available too.
