Low-cost high-performance siliceous porcelain blank formula
The invention relates to the technical field of electrical porcelain, in particular to a formula of a low-cost high-performance siliceous porcelain blank. The auxiliary materials comprise a plastic additive, water, an inorganic auxiliary agent and inorganic salt; every 100 parts by weight of the main material and 13 parts by weight of the auxiliary material are matched. The main material and the auxiliary material are mixed to form a blank, and the blank is prepared into a biscuit through pressing, extruding, grouting or other forming methods. Under the chemical combination of the plastic additive, the wollastonite mixture is pyrolyzed into porous carbon, liquid or gaseous silicon reacts with amorphous carbon or graphite to generate silicon carbide, and silicon nitride ore obtained through nitridation reaction is included. Silicon carbide polycrystals, silicon carbide powder and silicon nitride generated by the reaction are connected into a whole, and micropores are filled with excessive silicon to obtain a pore-free product. Under the environment of 25 DEG C, the bending strength can reach 400-600 MPa, the melting point is 1410 DEG C, the strength is 250 MPa, and the elastic modulus is about 115 MPa.
本发明涉及电瓷技术领域，尤其涉及一种低成本高性能硅质瓷坯料配方，主料包括硅灰矿石；辅料包括塑性添加剂、水、无机助剂和无机盐；按重量份数计，每100份主料与13份辅料进行配比。本发明得主料和辅料混合后形成坯料，坯料经压制、挤压、注浆或其他成型方法制成素坯。在塑性添加剂的化合所用下，硅灰矿石混合物热解为多孔的炭，液态或气态的硅与无定型碳或石墨反应生成碳化硅，并且包括氮化反应得到的氮化硅矿石。反应生成的碳化硅多晶、碳化硅粉和氮化硅连成一体，过量的硅填充了微孔得到无气孔的制品。25°C环境下弯曲强度可达400～600MPa,熔点为1410℃，强度250MPa，弹性模量约为115MPa。
