Abstract: | Natural and artificial wollastonite is used in the production of ceramics, devitrified glass (sitall), and as a polymer filler. Wollastonite additives decrease the firing temperature of ceramics, improve their strength, decrease the firing and drying shrinkages and the temperature of formation of the vitreous phase. Due to the high dielectric parameters, wollastonite ceramics are used in electrical and radio engineering. The use of wollastonite in the ceramics industry has good prospects.Translated from Steklo i Keramika, No. 9, pp. 13–16, September, 1995. |
