description	product containing a small amount of free silicon and a preparation method thereof. The reaction- bonded. SiC jproduct includes the following' components in parts by weight: 20-30 parts of purified water, 25-35 parts of Sic micropowder, 40-65 parts of SiC coarse particles, 6- 10 parts of carbon black, and 1.1-2.3 parts of binding agent. The content of free silicon in the reaction-bonded SiC product obtained by the present invention is less than or equal to 4%. Upon testing, the bulk density of a green body is 2.38-2.48 g/cm3, the bulk density of a finished product is 3.07-3.12 g/cm3, the bending strength at 20 degrees Celsius is about 270-300 MPa, and the bending strength at 1,200 degrees Celsius is about 290-330 MPa. The preparation strength, bulk density and bending strength at different temperatures of the green body are greatly improved.
