A process of fast uniform mixing A controllable colloidal forming of ceramics was invented to thoroughly avoid the crucial effect of temperature on colloidal forming of ceramics. The ceramic suspension was divided into two components A and B. The monomer was added into A, and the initiator was added into B. Under this condition, there were no reactions in separate A or B because of segregation of the monomer and the initiator. Both of the suspensions could keep good fluidity until they were mixed quickly and uniformly. The mixture would fast solidify under a determined pressure. The highly automatic equipment also had been developed for this process.
