Manufacture of vitreous silica product |
摘要 |
<p>Lowered cost fabrication including preparation of large bodies of void- free, high-silica glass, depends upon gellation of an aqueous sol of colloidal silica particles, followed by drying and firing of such gel. Freedom from cracks in the dried gel is the consequence of included polymeric material which wets the particles. The polymeric material is removed by thermal decomposition attended upon temperature attained in firing. <IMAGE></p> |
