Silicon carbide coated graphite disk is to prepare silicon carbide protective layer on the surface of graphite by physical or chemical vapor deposition and spraying. The prepared silicon carbide pr...
A wafer has to go through three changes to become a real semiconductor chip: first, the block-shaped ingot is cut into wafers; in the second process, transistors are engraved on the front of the wa...
Why do graphite crucibles crack? How to solve it?
The following is a detailed analysis of the causes of cracks:
1. After the crucible is used for a long time, the crucible wall presents longitudin...
When silicon carbide crystal grows, the “environment” of the growth interface between the axial center of the crystal and the edge is different, so that the crystal stress on the edge i...
In recent years, the industrial world has seen the increasing use of advanced materials that offer enhanced durability, strength, and thermal resistance. Among these, rigid graphite felt has emerge...
As a kind of power generation device that converts chemical energy in hydrogen and oxidant into electricity, the gas tightness of fuel cell stack is very important. This is the test of VET for the ...
