alumina ceramics, as the most widely used material in advanced ceramics, show the following trends along with the development of the whole industry. (1) the level of technical equipment will be improved rapidly: the development of computer technology and digital control technology has promoted the technological progress and rapid development of advanced ceramic materials industry, such as automatic control of continuous sintering kiln, high-power large capacity grinding equipment, high performance powder granulation equipment and other advanced complete set of equipment. it has promoted the overall level of the industry and improved production efficiency and product quality. (2) the quality level of the product is continuously improved: the domestic microcrystalline alumina ceramics products are from scratch, the industrial scale is from small to large, the quality of the products is from low to high, and has experienced a rapid development course. (3) the scale of industry will be expanded rapidly: microcrystalline alumina ceramics products, as the basic materials of other industries or fields, are affected and restricted by the development level of other industries. from the current application of alumina ceramics, the application range is wider and wider and the amount is increasing, especially in the field of anti-wear engineering and building ceramic production, which will be more significant.
