YUFENGREC
YUFENGREC Fused Silica Ceramic Crucible are made of high pure fused silica raw mateiral , as it 's characteristics of fine structure, low thermal conductivity, small thermal expansion coefficient, high dimensional accuracy of finished products, no deformation at high temperature, good thermal shock resistance, good electrical properties and good chemical corrosion resistance. Therefore, it is in the glass deep processing industry and metallurgical industry, electronics industry, chemical industry, aerospace and other fields have been widely used.
