Gel forming refers to the constant position of particles in the suspended body, and the suspended body changes from liquid to solid by the force between particles or the properties of some carriers inside the suspended body. Gel forming technology successfully combine powder molding process and organic polymer chemistry, to join the ceramic slurry, functioning monomer molecules through the preparation of low viscosity high solid ceramic slurry, reoccupy add catalyst or heating or cooling cause organic molecules in the slurry crosslinking polymerization to form a three-dimensional network using molecules formed in situ curing of 3 d mesh structure fixed ceramic particles in situ, The formation of more dense than traditional ceramics without pores of the body.
