The market demand for silica micropowder is strong and the industry has broad development prospects

Microsilica powder, also known as quartz powder, refers to silica powder made from quartz as raw material through multiple processing procedures. Microsilica powder is an inorganic non-metallic material with the advantages of stable chemical properties, non-toxic, environmentally friendly, heat-resistant and corrosion-resistant. According to different levels, silica powder can be divided into ordinary silica powder, ultrafine silica powder, electronic grade silica powder, spherical silica powder, etc. Silica powder products, as functional fillers, are widely used in insulation materials, coatings, ceramics, refractory materials, integrated circuits and other fields.

The raw materials for the production of microsilica powder mainly come from natural quartz or fused quartz. my country is rich in quartz resources and the mineral sources are widely distributed. At present, there are nearly 200 proven quartz mines and 15.0 billion tons of high-grade quartz mines. Benefiting from sufficient supply of raw materials and strong market demand, my country’s production and sales of microsilica powder have continued to grow, and China has become a major producer and consumer of microsilica powder.

According to the “2022-2027 China Microsilica Powder Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, silicon Micropowder market demand is related to the development of application fields. With the rapid development of high technologies such as artificial intelligence, chips, and 5G, the prosperity of my country’s semiconductor industry continues to increase. As a core material for semiconductor manufacturing, copper-clad laminate production is growing rapidly. As a raw material for the production of copper-clad laminates, the market demand for silica micropowder continues to grow. In 2021, my country’s silica powder market will reach 2.46 billion yuan, a year-on-year increase of 17.9%. With continuous breakthroughs in production technology, it is expected that my country’s silica powder market will continue to grow in the future and will exceed 5.5 billion yuan by 2025.

The production process of silica powder includes dry grinding and wet grinding. Dry grinding refers to putting natural quartz or fused quartz into grinding equipment, and then going through processes such as crushing, sieving, fine grinding, and impurity removal, and finally prepares silica powder. Wet grinding requires adding an appropriate amount of water during the grinding process, and then going through steps such as filter pressing, crushing, and drying to produce silica powder. At present, there is still a certain gap between my country’s silica powder production technology and overseas advanced levels, which is the main challenge facing the development of the industry.

In recent years, spherical silica powder has gained broad market space as a subdivision of silica powder. Compared with angular silica powder, spherical silica powder has the advantages of higher strength, small friction coefficient, and small thermal expansion coefficient, and can produce electronic components with excellent performance. However, due to the difficulty of production technology, the degree of localization of spherical silica powder in my country is relatively low.

Industry analysts said that silica powder is an important raw material for semiconductor production. In recent years, my country’s silica powder industry has developed strongly, and its output has reached The market size maintains rapid growth. my country is a major producer and consumer of silica powder. Driven by positive factors such as continuous technological advancement, the localization process of high-end silica powder products will be further accelerated, which will promote the development of the industry.
