Current types of imported high-alumina raw materials for refractory production

The major types of high-alumina raw materials used in Russian refractory plants are considered. The main principles in developing the supply of high-quality alumina raw materials to the world market are shown by the example of the Alcoa Company (US). Some information on materials little known in Russia is presented. Among the materials are tabular alumina, reactive alumina, high-alumina cement, etc. The basic requirements on the properties and parameters of high-alumina materials that are delivered to the leading refractory enterprises are given. The main areas of application of the materials to production at domestic plants of the metallurgy and refractory industry are defined.
