electrofused zirconia is zirconia obtained by one-step electric arc furnace smelting, which has the advantages of simple process, short process and low product cost. The development status of electrofused zirconia at home and abroad is briefly introduced, and then the development and technological innovation of electrofused zirconia preparation technology in China in recent years are summarized, as well as the application and market demand of electrofused zirconia in refractory materials, ceramic colors, ceramic products, abrasives and metal zirconium, etc. At the same time, the main problems in the current electrofused zirconia preparation technology are analyzed, and the production and application trends of electrofused zirconia are pointed out.
zirconia has excellent properties such as corrosion resistance, good thermal stability, high refractive index, and good thermal shock resistance. It is one of the emerging materials that have developed rapidly in recent years. The application of stabilized zirconia incorporating stabilizers in structural and functional ceramics has given rise to the rapid development of zirconia in the field of new material applications. At present, the preparation methods of zirconia mainly include chemical method and electric melting method, in which the high purity zirconia produced by chemical method has excellent performance, and the performance of the product is easy to control in the production process, which is the application of zirconia in advanced science and technology materials, and promotes the application prospect of zirconia to a certain extent. However, the chemical process is long, the consumption of decomposition reagents is large, and the product cost is high, so it cannot be widely used in the fields of ordinary ceramics, refractory materials and ceramic glaze.
Electromelting zirconia is obtained by one-step electric arc furnace melting zirconia, its process is simple, short process, low product cost, but the performance is inferior to the chemical production of zirconia. However, it is believed that with the in-depth study of electrofusion method, the improvement of product quality, the diversification of product structure, and the outstanding performance in energy saving, electrofused zirconia will have great development prospects and is expected to replace chemical zirconia. It is used in refractory materials, ordinary ceramics and ceramic color glaze.
