Specialty alumina activated alumina ball is applied to a set of properties of petrochemical, fertilizer and other industries as catalysts or catalyst supports large differences unique products. According to the nature or purpose may be divided into a number of brands and models, and its high-tech manufacturing process, and therefore economic benefits are substantial. Quality products in the market price per ton ranging from 10,000 to 100,000 yuan level number. However, some high-end products currently can not produce or no large-volume manufacturers, domestic manufacturers use to spend a lot of foreign exchange to import such products. Currently there are some manufacturers may be some small batch of high-end products, the product quality is close to the level of foreign investment as long as people pay attention and appropriate, high-grade production is entirely possible. Can then homegrown, even export to earn foreign money. State sintered alumina production of specialty alumina manufacturer has four decades of history, the brand has over a hundred varieties of species, can be summarized as aluminum hydroxide series, to be boehmite series, activated alumina series, calcined Alumina, high-purity alumina series aluminum calcium cement and its derivatives series and molecular sieves series. These products are widely used in various industries, is closely related to the development of the national economy. Specialty alumina refers to non-metallurgical alumina, and the output is a special processing of the unique nature of the economic benefits the rich or alumina hydrate. Specialty alumina for low grade bauxite resource-poor producers, especially for the relatively high cost of the sintering process manufacturers, undoubtedly develop production, improve efficiency, increase employment opportunities of a road. Therefore, the development of specialty alumina should arouse people's attention.
