Description

(54) CERAMIC MASS

The invention relates to compositions of ceramic masses and can be used in the manufacture of porcelain products. The ceramic composition is known, which includes the following components, weight,: Clayey material Quartz sand Perlite The closest to the invention is a ceramic weight, including the following components, weight,%: Clay material 50 Quartz sand 25 Plav25 Magnesium-containing component - talc The disadvantage of this mass is high water absorption and relatively low strength and heat resistance of products. The aim of the invention is to reduce water absorption, increase strength and heat resistance. This is achieved by the fact that the ceramic mass, including the clay component, quartz sand, flux and magnesium-containing component contains magnesite as an magnesium-containing component and additionally porcelain blasts in the following ratio of components, wt.%: Clay component 30-60 Quartz sand 20-25 Smooth 10–20 Magnesite 2–10 Porcelain fights 8–15. Ceplastic components of the charge — nepheline concentrate; fluids, quartz sand, porcelain fights and magnesite are mixed in certain ratios and milled in a wetrope mill. grinding to a residue on the sieve 006-1. The clay is dissolved in water until a suspension of a certain moisture content is obtained. Suspension of emaciated and smoothly mixed with a clay suspension in certain ratios. Electrolytes in the form of soda and liquid glass are injected into the extractor. Table 1 shows the approximate compositions of the masses. From the compositions prepared in conical molds, products are cast, which, after releasing the molds, are poured, dried and calcined at 1140IISO C.

The properties of the calcined products are given in table 2,

These compounds are used to obtain porcelain products on clay clay matter quartz sand porcelain battles Plaven magnesite {MgCO-)
