Alumina ceramics status and trends

Alumina ceramics, with high hardness, high strength, high-temperature resistance, corrosion resistance, and good electrical insulation characteristics. Widely used as powder smelting, textile machinery, electronic and electrical appliances, engineering machinery wear-resistant, high-temperature resistant, corrosion-resistant, insulating devices. So, do you know the status and trends of alumina ceramics, let's take a look.

Analysis of the current situation of alumina ceramics

Since the reform and opening-up, China's alumina ceramic industry has gained rapid development, with China's accession to the WTO, the alumina ceramic industry is facing an unprecedented opportunity for development, but also faced unprecedented challenges. China's alumina ceramic enterprises are mainly located on the southeast coast, such as Foshan in Guangdong, Jinjiang in Fujian, Wenzhou in Zhejiang, Tangshan in Hebei, Zibo, and Weifang in Shandong, and so on. Enterprises are excessively concentrated in a few areas, this status quo although it has a favorable side, we must not ignore the negative side. First, this over-concentration will cause serious local duplication of construction and waste of resources, not conducive to the comprehensive and sustainable development of China's building ceramics industry; Second, easy to causes vicious competition between enterprises, not conducive to the healthy development of China's building ceramics industry; Third, easy to cause the local supply of products than demand, and excess part of the product to be exported, especially to more distant (such as the northeast, northwest, etc.) Area, sales costs will undoubtedly increase; Fourth, easy to cause the lack of major raw materials, these raw materials purchased in large quantities for a long time, will also increase production costs.

Development trend of alumina ceramics

Alumina ceramics as advanced ceramics in the most widely used material, along with the development of the entire industry presents the following development trends.

(1) The level of technology and equipment will rapidly improve: the development of computer technology and digital control technology to promote the technical progress and rapid development of advanced alumina ceramic materials industry, such as automatic control of continuous sintering kilns, high-powered large-capacity grinding equipment, high-performance powder granulation equipment, such as net pressure forming equipment and another advanced alumina ceramic equipment to promote the overall level of the industry to improve, while in the production efficiency, product quality and other aspects are also significantly improved.

(2) Continuous improvement in product quality level: domestic microcrystalline alumina ceramic products have undergone rapid development from scratch, from small to large industrial scale, and from low to high product quality.

(3) The industry scale will expand rapidly: microcrystalline alumina ceramic products as the basic materials of other industries or fields, subject to the influence and limitations of the development level of other industries. From the application of alumina ceramics, the application range is getting wider and wider, and the dosage is getting bigger and bigger, especially in the anti-wear engineering and architectural ceramics production will increase the dosage more significantly.
