Porous Tantalum Carbide Description

Porous Tantalum Carbide developed by Stanford Advanced Materials (SAM) is a cutting-edge material engineered to meet the demanding requirements of next-generation SiC crystal growth systems. With an exceptionally high porosity of up to 75%, this material offers excellent gas permeability, enabling precise control of vapor-phase composition, local temperature gradients, and material flow direction within the thermal field. Unlike conventional graphite or porous graphite materials that may lead to carbon-related defects or suffer from insufficient permeability, SAM’s porous tantalum carbide combines superior hardness, strength, and purity—making it ideal for high-temperature environments where structural integrity and thermal stability are critical.
