Basic Introduction
HIPER has launched a new generation of SiC crystal growth thermal field material - porous tantalum carbide, which is mainly used for gas phase component filtration, adjusting local temperature gradients, guiding the direction of material flow, and controlling leakage. It can be combined with another solid tantalum carbide (dense) or tantalum carbide coating of Hengpu Technology to form components with locally different conductances.
Due to improper use of crucible materials in the thermal field, such as graphite, porous graphite, and tantalum carbide powder, it will cause defects such as increased carbon inclusions. In addition, in some applications, the air permeability of porous graphite is not enough, and additional openings are required to increase the air permeability. Porous graphite with high air permeability faces challenges such as processing, powder dropping, and etching. HIPER has made a breakthrough in launching high-purity porous tantalum carbide with large porosity. The maximum porosity can reach 75%, which is an international leader.
