Alumina Ceramics:
China's chemical alumina industry started late. Before and after 1961, in order to solve the shortage of raw materials in the electronics industry, Shandong Aluminum Factory (now known as Shandong Aluminum Co., Ltd.) first developed low-α alpha alumina, which has since started. Research and production and production of chemical alumina in China. In the 1970s, in order to meet the demand for chemical alumina in petroleum, chemical, refractory materials, ceramics, pharmaceutical, environmental protection, weapons, aerospace and other industries, Shandong Aluminum Plant and Zhengzhou Light Metal Research Institute successively developed and produced activities. 24 new products such as alumina, arsenic and fluoride removal agent alumina, low iron aluminum hydroxide, high purity alumina, α-Al2O3 for ceramics, and alumina for spraying. In the 1980s, China's chemical alumina production entered a period of rapid development, and new products continued to emerge. With Zhengzhou Light Metal Research Institute, Shandong Aluminum Industry Co., Ltd. and China Great Wall Aluminum Co., Ltd., about 60 special oxidations were built. Aluminum production line. A number of private enterprises that produce chemical alumina have been built in the surrounding areas of some large alumina enterprises. They use domestic or imported raw materials to produce various chemical aluminas.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
