Silicon carbide blank and preparation method thereof
The invention relates to a silicon carbide blank and a preparation method thereof, and the preparation method specifically comprises the following steps: firstly, adding water into a proper amount of silicon carbide powder, carbon black, graphite powder and an auxiliary agent, and mixing and stirring to obtain a mixed ingredient; then injecting the mixed material into a press for extrusion molding to obtain an extruded blank; and drying to obtain a biscuit. The density rho of the biscuit finally obtained through the method is 2.10-2.4 g/cm < 3 >, the water content is smaller than or equal to 0.1%, the texture and color are uniform, and the carbon black agglomeration phenomenon is avoided. According to the method, the density rho of the biscuit is equal to (rho 1 * n1 * w1 + rho 2 * n2 * w2 + rho 3 * n3 * w3) * a * b * c * d * e, the biscuit density with the preset value can be accurately obtained, the method has great significance in the actual production process, and economic production of enterprises is promoted.
本发明涉及一种碳化硅素胚及其制备方法，所述制备方法具体包括如下步骤：首先将适量碳化硅粉、炭黑、石墨粉和助剂加水后混合搅拌，得到混合配料；然后将混合配料注入压机挤出成型得到挤出坯体；干燥后得到素坯。本发明所述方法最终得到的素坯的密度ρ为2.10～2.4g/cm3，含水率≤0.1％，且质地和颜色均匀，且无炭黑团聚现象。且通过本发明所述方法，借助素坯的密度ρ＝(ρ1*n1*w1+ρ2*n2*w2+ρ3*n3*w3)*a*b*c*d*e，可以精确得到预先设定值的素坯密度，在实际生产过程中具有重大意义，有利于促进企业的经济生产。
