my country is a major producer of manganese tetroxide, and electronic grade manganese tetroxide is the mainstream product in the market.

Manganese tetraoxide, also known as active manganese oxide and manganese oxide, has a molecular formula of Mn3O4 and is an oxide. Manganese tetroxide appears as a brown-black powder, soluble in concentrated sulfuric acid and concentrated hydrochloric acid, but insoluble in water. Manganese tetroxide has the advantages of good chemical stability, excellent electrical properties, and corrosion resistance. It is widely used in electronic and electrical, optical glass, paint and coating, automobile manufacturing and other fields.

There are many methods for preparing manganese tetroxide, including four main methods: mixed burning method, high temperature burning method, reduction method and roasting method. The mixed burning method refers to using carbonates, hydroxides, manganese oxides, sulfates, etc. as raw materials, and burns them to obtain manganese tetroxide; the high-temperature burning method refers to burning the raw materials at high temperature first, and then cooling and pulverizing them. , roasting and other processes to obtain finished products; the reduction method refers to using hydromanganese ore and manganese dioxide as raw materials, and then roasting, reducing, cooling, and crushing to obtain finished products.

​​​​According to different uses, manganese tetroxide can be divided into two categories: battery grade and electronic grade. Battery-grade manganese tetroxide has high requirements on raw material quality and production process. It can usually be used as the cathode material of lithium iron manganese phosphate batteries and lithium manganate. Electronic-grade manganese tetroxide has a wide range of applications, including home appliances, automobiles, and electric power. Systems, communication systems, etc., are mainstream products in the manganese tetroxide market. In 2022, my country’s electronic grade manganese tetroxide production will reach 96,000 tons, accounting for nearly 60% of the total manganese tetroxide production.

my country is a major producer of manganese tetroxide, with its production capacity and output ranking first in the world. Guizhou, Hunan, Guangxi, Anhui and other places are the main producing areas of manganese tetroxide in my country. In recent years, benefiting from the accelerated development of lithium batteries, new energy vehicles, car charging piles, 5G communications and other industries, the market demand for manganese tetroxide has become increasingly strong, and its output has continued to grow. According to the “2023-2028 China Trimanganese Tetroxide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , my country’s manganese tetroxide production will reach nearly 160,000 tons in 2022.

In terms of market competition, my country’s manganese tetroxide industry has a high degree of concentration, and leading companies have a competitive advantage in the global market. Sinosteel Tianyuan Co., Ltd. and Hangzhou Jinrui Technology Co., Ltd. are the main manufacturers of manganese tetroxide in my country. Sinosteel Tianyuan focuses on the R&D, production and sales of high-purity trimanganese tetraoxide, and its technology ranks among the world’s leaders. According to the annual report of Sinosteel Tianyuan, the company’s battery-grade manganese tetroxide production capacity will reach 5,000 tons in 2022; and the electronic-grade manganese tetroxide production capacity will reach 50,000 tons.

           Industry analysts said that manganese tetroxide has a wide range of applications and the industry is developing well. my country is a major producer of manganese tetroxide. As its technological maturity continues to improve, its production capacity continues to expand and its output continues to grow. Electronic grade manganese tetroxide is a mainstream product in the manganese tetroxide market, and its application demand is increasingly strong, driving the prosperity of the manganese tetroxide industry to further increase.
