Zirconia balls have the advantages of high strength and high toughness at room temperature. Zirconia balls also have good wear resistance, high temperature resistance and corrosion resistance. High-strength zirconia beads are currently the ideal grinding material. Zirconium balls are widely used in ultrafine grinding and dispersion of materials in industries such as non-metallic minerals, coatings, inks, paints, dyes, titanium dioxide, pesticides, and magnetic materials. Zirconia balls have become an indispensable part of the industry, so how are zirconia balls made and what has the development of zirconia balls been experienced?
First of all, the development of zirconia balls can be traced back to 1975. In 1975, an Australian scholar proposed to use zr2o transformation to increase the toughness of ceramics. Then zro2 began to receive widespread attention and became very popular. This substance was initially extracted from gems, and most of it was first used in gas lampshades. Later, zirconia materials were gradually used in refractory materials, coloring materials and abrasives.
Zirconia products are mainly white, but if they contain impurities, they will appear gray or yellow, which is very difficult to separate. The production of zirconia products requires good dispersion performance, high purity and ultrafine particles, etc., while zirconia ultrafine powders are manufactured in many ways, but zirconia can be mainly divided into lime in the way of purification. The melting method, hydrolysis method, thermal decomposition method, precipitation method, spray pyrolysis method and plasma arc method.
In recent years, due to the continuous advancement of science and technology, zirconia has been developed to develop more excellent functions, resulting in more high-performance new products, and the application field of zirconia balls is also expanding. Beginning in the refractory industry, and later in the ceramic industry and various industries, zirconia balls are one of the high-performance products. Zirconia is also one of the high-performance new materials encouraged by the national industrial policy. Gradually applied in various industries.
