Abstract

The invention discloses a sintering-free ceramic body material and a preparation method thereof. The ceramic body material is prepared from metakaolin or blast furnace slag, sodium silicate and water, wherein a weight ratio of the metakaolin or blast furnace slag to sodium silicate is (1-1.5):1, and the addition amount of water accounts for 10-20 percent of the total weight of the metakaolin or blast furnace slag and the sodium silicate. The sintering-free ceramic body material disclosed by the invention has the innovative characteristics that the green body is sintering-free, a low-temperature fired glaze at the temperature of about 600-800 DEG C can be applied to the surface and the production period is short. Meanwhile, the conventional universal green body paste of the traditional high-temperature ceramics can be replaced, large-scale industrial production is realized, millions of energy cost even more money can be saved for ceramic enterprises, and the ceramic body material has high significance for protecting the environmental resources.

Description

technical field [0001] The invention relates to the technical field of ceramic processing, in particular to a sinter-free ceramic body material and a preparation method thereof. Background technique [0002] In the 21st century, with the continuous progress and development of science and technology, human society has entered a stage of highly developed material civilization. Traditional ceramic materials are one of the earliest materials used by humans. They mainly use natural rocks, minerals, clay and other materials as raw materials, and use coal, oil, and gas as the main fuels. Ceramic products are fired at high temperatures above 1200 °C. The traditional ceramic industry belongs to the "two high and one porcelain" industries, that is, high energy consumption, high pollution, resource-consuming industries, and the contradiction between economic development and resource environment is very prominent. This traditional "two highs and one porcelain" extensive industrial stru...
