Abstract

PURPOSE:To improve the quality of quartz crucible and to reduce the production cost by using silicone rubber to envelop a core unit wrapping up a center core material with paper and gelling the sol type raw material of quartz crucible by using a mold. CONSTITUTION:In the production of quartz crucible by the production technique of sol-gel method gelling a sol type raw taterial by using a mold, the center core material and the paper wrapping up the center core material are used to form the core unit, and the silicone rubber is used for covering the paper. In this production, the core material is the mother material working to keep the shape of the core unit, and the paper wrapping the core material exists between the core material and the silicone rubber and has the function that friction is reduced to smoothly move the core material when it is moved in and out. The silicone rubber has also the function that the silicone rubber is contracted by the contracting force of gel when the gel contracts so that repulsion force does not act on the gel and cracks are not generated in the gel.
