1.Development of the alumina tiles
Since the reform and opening up, China's building ceramic industry obtained rapid development, with China's accession to the WTO, the building ceramic industry is facing an unprecedented development opportunity, at the same time also faced with unprecedented challenges. China's construction ceramics enterprises are mainly distributed along the southeast coast, such as zibo city in Shandong jinjiang in fujian, wenzhou in zhejiang, tangshan in hebei, and weifang. There is a good side to this situation, which is too concentrated in a few regions, but we must not ignore its disadvantages. Firstly, the over-concentration of this feature can cause serious local duplication and waste of resources, which is not conducive to the comprehensive and sustainable development of China's construction ceramics industry. Secondly, it is easy to create vicious competition among enterprises, which is not conducive to the healthy development of China's construction ceramics industry. Third, it is easy to create a local oversupply of products, while the surplus part of the product will be exported to more distant (such as northeast, northwest, etc.), and the cost of selling will undoubtedly increase. Fourth, the lack of major raw materials is easy to make, which will also increase production costs.
2. Development trend of the alumina tiles
Alumina ceramic tiles, as one of the most widely used in advanced ceramics material, with the development of the industry presents the following trends:
(1) technical equipment level will increase rapidly, the development of computer technology and digital control technology to promote the technology progress of the advanced ceramic materials industry and rapid development, such as automatic control of continuous sintering furnace, high-power high-capacity grinding equipment, high-performance powder granulation equipment net pressure molding equipment advanced complete sets of equipment, such as favorable to promote the improvement of the industry as a whole, at the same time in such aspects as production efficiency, product quality are improved obviously;
(2) the increasing level of product quality: microcrystalline alumina ceramic products from domestic and industrial scale since the childhood, from low to high product quality, has experienced a rapid development;
(3) the scale of the industry will be expanded rapidly: microcrystalline alumina ceramic products as the base material in other industries or sectors are affected and restricted by the development level of other industries. From the application of alumina ceramics, the application scope is more and more wide, the dosage is increasing, especially in the anti-wear engineering and construction ceramics production.
