Nano-zirconia is an important raw material for special ceramics and the industry has good development prospects

Nano-zirconia, also known as nano-zirconia, has a molecular formula of ZrO2 and is one of the important raw materials for the preparation of special ceramics. Nano-zirconium dioxide appears as white powder with no special odor, is soluble in hydrofluoric acid and sulfuric acid, and is almost insoluble in water. According to the sintering temperature and the content of added stabilizers such as yttrium oxide, nano-zirconia can be divided into three types: tetragonal phase, monoclinic phase and cubic phase. Nano-zirconium dioxide has the characteristics of high temperature resistance, strong thermal shock resistance, small particle size, corrosion resistance, acid and alkali resistance, etc., and is widely used in nanocatalysts, special ceramics, medical materials, aerospace, infrared spectrometers and other fields.

The main preparation processes of nanometer zirconium dioxide include alkoxide hydrolysis method, zirconium oxychloride pyrolysis method, impregnation method, high temperature hydrolysis method, sol-gel method, etc. The zirconium oxychloride pyrolysis method is suitable for the preparation of high-purity nano-zirconium dioxide. It refers to the melting of zircon stone and caustic soda under high temperature conditions, and the finished product is obtained through processes such as separation, impurity removal, precipitation, evaporation, cooling, crushing, and roasting. .

Zircon is the main raw material for preparing nano-zirconium dioxide. It has the characteristics of high thermal conductivity, low thermal expansion and strong chemical stability. my country’s zirconium resources are relatively scarce, and the output of zircon concentrate is very small, and it needs to rely on large quantities of imports, which has caused certain obstacles to the development of high-quality zirconium chemical industries such as nano-zirconium dioxide.

According to the “2023-2028 China Nano-zirconia Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Nano-zirconium dioxide has a wide range of applications, and special ceramics are its largest demand end. Special ceramics are modern ceramic subdivision products and are widely used in many fields such as metal smelting, semiconductors, medicine, chemical industry, and new energy vehicles. In 2022, my country’s special ceramics market will exceed 92 billion yuan, accounting for nearly 30% of the global market. With the rapid development of downstream industries, the market demand for nano-zirconium dioxide is increasingly strong. In 2022, my country’s demand for dental nano-zirconium dioxide will reach 2,200 tons.

my country’s nano-zirconium dioxide market is highly competitive with many manufacturers, including Wuhan Penglai Biotechnology Co., Ltd., Guizhou Kaizhong Technology Co., Ltd., Hangzhou Hengna New Materials Co., Ltd., Guangzhou Hongwu Materials Technology Co., Ltd., and Suzhou Youzirconium Nanomaterials Co., Ltd., Shanghai Chaowei Nano Technology Co., Ltd., etc. With continuous breakthroughs in production technology, the quality and output of my country’s nano-zirconium dioxide continue to improve, and the products are exported to countries and regions such as the United States, South Korea, Japan, and Taiwan.

Industry analysts said that nanometer zirconium dioxide has the advantages of high temperature resistance and strong thermal shock resistance, and has been widely used in many fields. . With the continuous deepening of research and the continuous innovation of production technology, the application prospects of nano-zirconium dioxide in my country will be broader. Driven by the rapid development of local enterprises, my country’s nano-zirconium dioxide industry has begun to develop in a high-quality direction.
