On April 18th, the 2018 National Alumina Powder Preparation and Application Technology Exchange Conference, sponsored by the Powder Circle and co-organized by Chinalco Zhongzhou New Materials Technology Co., Ltd., was held in Zhongzhou Hotel, Jiaozuo City, Henan Province. Nearly 400 experts, scholars and business representatives from the multi-variety alumina industry chain gathered together to exchange and share the development of the industry. China Superhard Materials Network, China Abrasives Network and China Coating Abrasives Network participated in the meeting as media support units.
The conference focused on the preparation, application and development of alumina powder. It is understood that the preparation method of alumina powder can be divided into two types: mechanical pulverization preparation and chemical preparation. With the cross-border application of powder technology, the application of sand mill in the preparation of submicron alumina powder. Stand out from the crowd. Alumina powder is also widely used in ceramics, electrical insulation materials, grinding and polishing, lithium ceramic diaphragms, sensors, high temperature insulation, purification filtration and other fields. The international production of many varieties of alumina accounts for about 9% of the total alumina, while China is less than 5%. In the context of the serious overcapacity of metallurgical alumina, the multi-variety alumina products have high technical content and high added value. The prospects for its development are even more worth looking forward to. Especially in the hotspot industry chain such as lithium battery and mobile phone, the application of high-purity nano-alumina powder in lithium-ion ceramic diaphragm and sapphire screen is a hot topic. In addition, the application of boehmite in lithium battery diaphragm is also in full swing. More updated applications for alumina are also being developed.
At the meeting, Shanghai Institute of Ceramics, Chinese Academy of Sciences, Zhengzhou Nonferrous Metal Research Institute of China Aluminum, Institute of Process Engineering of Chinese Academy of Sciences, Hunan University, Dalian Jiaotong University, Henan University of Technology, Northwestern Polytechnical University, Zhengzhou University, etc. Well-known experts and scholars from the college attended the conference and presented 25 wonderful reports to the conference together with representatives from alumina powder production enterprises, crushing and grading testing equipment enterprises, alumina powder or slurry downstream users. In the content, "production, learning, research, use" is closely combined, covering new processes and new products of alumina powder preparation, application and development direction of alumina micropowder in ceramics, grinding and polishing, refractory industry, boehmite, high Application of pure alumina in lithium ceramic ceramic diaphragm, surface treatment and modification of alumina powder, preparation and application of alumina ceramic membrane, development and application of alumina micropowder processing equipment and technology, and quality inspection and control technology of alumina powder The entire industrial chain, taking into account the traditional application of alumina powder and the development of emerging markets.
The report also set up a Q&A session on the spot. The representatives of the audience gave a speech and asked questions and actively interacted with the experts on the stage.
During the conference, the exhibition of alumina powder preparation and application technology was held concurrently, and the atmosphere of the exhibition was strong.
