Product Description

 Customized grapphite crucible graphite parts for silicon crystal growth equipment
Product use: heating polycrystalline silicon ingot furnace
Features:
Graphite has good thermal conductivity and high temperature resistance. In the process of high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid heat and rapid cooling. It has strong corrosion resistance to acid and alkaline solutions and has excellent chemical stability.
In the field of semiconductor and solar photovoltaic power generation, there are many graphite parts for silicon crystal growth equipment, such as graphite crucible, graphite thermal field, graphite cover plate, graphite seat for silicon wafer epitaxy, graphite insulation cover and carbon insulation material, etc. The graphite parts used are also With the development of silicon crystal size technology, graphite crucibles, graphite thermal fields and other materials are required to have high purity and large-scale, and develop to high-end sophisticated technology.

 The graphite has the following characteristics:
