~Fused silica crucible crucible is a kind of combined product,made of  fused silica as raw material.
High purity fused silica with fine structure, low thermal conductivity, low thermal expansion coefficient, the size of the finished goods of high precision, high temperature deformation, good thermal shock resistance, good electric properties and chemical erosion resistance is good wait for a characteristic,

therefore it's widely used in the glass processing industry, metallurgy industry, electronic industry, chemical industry, aerospace and other fields
