Abstract

The high strength light ceramic filler is prepared with clay 60-78 wt%, black earth 8-15 wt%, calcium carbonate 8-15 wt%, talcum 3-10 wt% and rice bran powder for the rest. Chemically, it consists of silica 50-60 wt%, alumina 13-20 wt%, calcium oxide 3-8 wt% and magnesia 10-16 wt% except impurity. It has high compression strength, long service life, low impurity content, high whiteness and high porosity.

Description

technical field [0001] The invention relates to a ceramic filler, in particular to a high-strength and light-weight ceramic filler. Background technique [0002] With the development of modern science and technology and modern industry, in the reaction tower of chemical industry and metallurgy industry, in the distillation tower of industrial treatment and filtration and pharmaceutical industry, in the washing and desulfurization of coking industry, a large amount of light specific gravity and wet It is a filler with strong sex and adsorption, high acid and alkali resistance, good resistance to rapid cooling and heat, high compressive strength, large specific surface area, and the surface is not easy to fall off, so as to achieve the purpose of industrial use and treatment. At present, there are many types of fillers used, which are made of metal materials, wood, plastic and clay materials. Among these types of fillers, although metal has high strength, it has low acid and a...
