The invention discloses ceramic pug. The ceramic pug is prepared from the following raw material components in parts by weight: 30-40 parts of kaolinite powder, 1-2 parts of nanosilicon dioxide, 2-3 parts of aluminium oxide, 2-5 parts of montmorillonite powder, 10-20 parts of mica powder, 15-20 parts of vermiculite powder, 5-10 parts of ceramsite powder, 3-5 parts of turf, 5-10 parts of zeolite powder, 10-15 parts of pyroxene powder, 10-15 parts of hornblende powder, 2-5 parts of magnesium oxide, 2-3 parts of ferric oxide, 3-5 parts of aluminium hydroxide, 5-8 parts of limestone, 2-3 parts of sodium metaaluminate, 3-5 parts of Na[Al(OH)4] and 5-8 parts of polycarboxylate water reducing agent. The ceramic pug has the advantages that the defects of easy deformation and unstable shrinkage ratio in a firing process are overcome, the shrinkage ratio is controlled under the synergistic effect of all the components in a formula, so that a product has small possibility of deformation in the firing process; meanwhile, firing shrinkage ratio is controlled to be 14-15%, the range of firing temperature of the product can be expanded, so that yield of fired products is high, and the requirement of large-scale industrial production is met.
