【Abstract】 Dipping SiC kiln furniture into Ca\-3(PO\-4)\-2 saturable solution can make it packed and decrease its porosity. It can also hinder the diffusion of oxygen, so cause the antioxygen property of SiC kiln furniture increased and the oxygenated velocity decreased with the dipping time and 4 times is the bast.The ratio of 1,2,3,4 times is K\-1∶K\-2∶K\-3∶K\-4=1.03×10\+\{-6\}∶8.94×10\+\{-7\}∶4.17×10\+\{-7\}∶2.65×10\+\{-7\}=3.89∶3.37∶1.57∶1.更多还原
