Preparation method of high-thermal-shock-resistance high-density sintered magnesia
The invention relates to a preparation method of high-thermal-shock-resistance high-density sintered magnesia, and the method comprises the following steps: finely grinding, mixing, pressing into balls, drying and calcining, to be more specific, mixing finely ground light calcined magnesia powder with Zr(OH)2 sol, pressing into the balls, drying and calcining to obtain the high-thermal-shock-resistance high-density sintered magnesia. Compared with the prior art, the method disclosed by the invention has the beneficial effects that the high-thermal-shock-resistance high-density sintered magnesia raw material can be directly prepared by taking the light-burned magnesia as a raw material, finely grinding, mixing with the Zr(OH)2 sol, pressing into the balls and calcining, and the method is simple in process flow, greatly reduces the cost, is easy to popularize and implement, and conforms to the energy-saving and environment-friendly concept.
本发明涉及一种高热震高致密烧结镁砂的制备方法，其制备过程包括细磨、混合、压球、干燥、煅烧，经细磨的轻烧氧化镁粉和Zr(OH)溶胶混合，经压球、干燥和煅烧，得到一种高热震高致密烧结镁砂。与现有技术相比，本发明的有益效果是：以轻烧镁砂为原料，通过细磨后与Zr(OH)溶胶混炼压球，煅烧后即可直接制得高热震高密度烧结镁砂原料，本发明工艺流程简单，使成本大幅降低，易于推广实施，且符合节能环保理念。
