Half-Century Epoch of Domestic Quartz Ceramic Development. Part 21

Abstract

Development and implementation of technology for manufacturing quartz ceramics for space rocket technology, and subsequently for casting steel, and refractories for other purposes are unique examples of high-tech domestic technology in the field of inorganic materials science. Distinguishing features of domestic technology of quartz ceramic manufacture are the high strength and reduced porosity of the original semiproduct that make it possible to achieve the required operating properties with a reduced firing temperature and insignificant shrinkage. Quartz refractories and engineering quartz ceramics have fundamentally different manufacturing technology.
