High-density ceramic material preparing method by normal-pressure slurry pouring
The invention relates to a high-density ceramic material preparing method by normal-pressure slurry pouring. The method includes firstly adding ceramic powder, 0.5% to 4% of water reducing agent, 0.8% to 4.0% of dispersing agent, 0.8% to 6% of reinforcing resin and 10% to 20% of water into a ball mill according to the certain proportion, dispersing the mixture evenly, and obtaining high-density slurry with the viscosity smaller than 200 centipoises; pouring the slurry into a product die at normal pressure, drying for 2 to 4 hours at normal temperature, stripping, and obtaining a dried blank after drying for 24 to 48 hours at the temperature of 40 to 70 DEG C; sintering and shaping the dried blank in a sintering furnace, adjusting the sintering temperature and time according to raw materials, and allowing the sintering density to be higher than 98% of the theoretical density. The process is simple and is especially adaptive to structure-complex, large-plane and high-density ceramic shaping.
