The sintering process and the degreasing experiments with porous ceramisites have been finished. The results show that the sintering temperature control is dominant for the preparation of the porous ceramisites. The optimal sintering temperature is between 1 110-1120℃, a narrow range. The surface of ceramists is distributed with a lot of coarse holes with diameters of about 1-10μm. Moreover, the sintering temperatures have a great influence on the efficiency of degreasing, and the curve between the sintering temperature and the efficiency ofdegreasing is like a parabola.展开更多

Brunauer-Emmett-Teller Procedure tests SSA of the ceramisite. Influences of sewage sludge content, adherent content and sintering point on the SSA of ceramisite made of river sediment are also analyzed. Results show that with the right sewage sludge content, adherent content and sintering point, the ceramisite can have the highest SSA value and be widely used.展开更多

Ceramisite comes in two forms—clay ceramisite and shale ceramisite. These ceramisites produced by Beijing City Tujiao Bricks and Tiles Factory and Beijing Ceramisite Factory include various ceramisites used for building, thermal insulation, water screen filtering, and sound absorption, They can be mixed with cement to produce quality light weight bricks and hollow blocks for different constructions. They also can be used as filtering materials. It is very popular at home and abroad and sells well in Japan and Korea. The sole agency for the product is the Beijing City Building Materials Import & Export Corporation.展开更多
