Description

Изобретение относится к составам шихты для производства абразивных керамических изделий.The invention relates to compositions of the mixture for the production of abrasive ceramic products.

Известна шихта, содержащая, мас. %: фарфоровый порошок 70-95; карбид кремний 5-30 [1].Known mixture containing, by weight. %: porcelain powder 70-95; silicon carbide 5-30 [1].

Цель изобретения - повышение прочности изделий из шихты.The purpose of the invention is to increase the strength of products from the charge.

Цель достигается тем, что в состав шихты, содержащей фарфоровый порошок и карбид кремния, дополнительно вводят тальк, триполифосфат натрия и волластонит при следующем соотношении компонентов, мас. %: фарфоровый порошок 70-75; карбид кремния 15-20; тальк 2,8-4,8; триполифосфат натрия 0,1-0,2; волластонит 5-7.The goal is achieved by the fact that talc, sodium tripolyphosphate and wollastonite are additionally introduced into the mixture containing porcelain powder and silicon carbide in the following ratio of components, wt. %: porcelain powder 70-75; silicon carbide 15-20; talc 2.8-4.8; sodium tripolyphosphate 0.1-0.2; wollastonite 5-7.

В таблице приведены составы шихты и прочность изделий из нее.The table shows the composition of the charge and the strength of products from it.
