Abstract

In article results of physical-chemical and technical characteristics melting glasses (a superficial tension, temperature dependence of viscosity, crystallization ability, contact angle of wetting) on the basis of sand and nonmetallic minerals is reduced. It is shown, that depending on a parity of sand and dolomite it is possible to receive homogeneous melting with different parameters of viscosity and crystallization abilities. The increase in contained dolomite leads to reduction of viscosity with simultaneous rise in temperature of crystallization beginning and narrowing of an interval of fibrolization.
