Abstract

  In article are offered results of research of sinter ability clayey silica clay. It is shown that the ceramic shard based on the silica clay have a low average density, increased firing shrinkage, porosity and water absorption. Increasing the firing temperature to a large extent determines the increase in shrinkage and reduced water absorption. At least increase the density. The data presented in the paper can be a useful technology of brick factories, employees testing laboratories and design companies, geologists studying nonmetallic raw materials, as well as undergraduate and graduate students specializing in this field.

Keywords: Silica clay, sinter ability, average density, water absorption, temperature, raw material
