Alumina polishing slurry is a metallographic sample polishing material, which refers to a high-performance polishing slurry prepared from alumina polishing powder and multiple solutions. Alumina polishing fluid has the advantages of being non-perishable, non-corrosive, safe and non-toxic, strong in grinding force, and high in hardness. It has broad application prospects in many fields such as electronics and electrical, glass, metal, and automobile manufacturing. According to different specifications, alumina polishing fluid can be divided into micron level and nano level.

The main raw material of alumina polishing slurry is alumina. As a multi-functional abrasive material, it has the advantages of high temperature resistance, good wear resistance, high mechanical strength, good electrical insulation properties, high compressive strength, and acid and alkali corrosion resistance. It is widely used in the field of polishing. According to different surface roughness, alumina can be divided into rough alumina, fine alumina, etc. Fine alumina has excellent properties and is an ideal material for alumina polishing fluids. However, the current output in my country is low, which brings certain challenges to the development of the alumina polishing fluid industry.

There are three methods for preparing aluminum oxide polishing liquid: liquid phase method, solid phase method and gas phase method. The liquid phase method has the advantages of low production cost, high finished product yield, and easy parameter control, and is the mainstream preparation method of alumina polishing liquid; the solid phase method can be subdivided into explosion method, aluminum ammonium sulfate pyrolysis method, etc., and its finished product yield It is relatively high and has a simple preparation process, but the quality of the finished product may be poor. The gas phase method is not suitable for industrial production and is rarely used in the preparation process of alumina polishing slurry.

According to the “2023-2028 China Alumina Polishing Slurry Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , electronic and electrical, glass, metal, automobile manufacturing and other fields are the main demand ends for alumina polishing fluid. In the electronic and electrical field, alumina polishing fluid can be used to polish semiconductor products and materials such as integrated circuits and silicon wafers. In recent years, the development of the global semiconductor industry has accelerated, driving the market demand for integrated circuits and silicon wafers to continue to grow. Against this background, the alumina polishing slurry market continues to expand, reaching 870 million yuan in 2022.

France’s Saint-Gobain Group, US company CMC Materials, Japan’s Fujimi Corporation, and Germany’s Nanoplus GmbH are world-renowned alumina polishing slurry manufacturers. The above four companies account for nearly 70% of the global market share. Compared with overseas developed countries, my country’s alumina polishing slurry industry started late. Local companies focus on the production of mid-to-low-end products, and high-end products are highly dependent on imports.

Industry analysts said that as a high-performance polishing slurry, alumina polishing slurry has a wide range of applications. In the future, with the continuous release of downstream demand, its The development trend of the industry will continue to improve. my country’s alumina polishing slurry industry started late, and there is a certain gap between the technical level of high-end products and overseas developed countries. Local companies urgently need to increase investment in research and development to further increase the market share of high-end alumina polishing solutions in my country.
