Silica fume provides valuable benefits for the building construction, hàng hải, and oil and gas sectors across the globe.
It is obtained as a by-product during the manufacture of silicon metal and ferrosilicon alloys and presents mainly pure silica in a non-crystalline form. While silicon itself is produced by heating quartz and carbon in a smelting furnace, silica fume that is released during the process is collected in a baghouse filter. It appears as a fine spherical particle that consists of amorphous silicon dioxide in high concentrations.
tại HSA, the leading provider of silica fume in China, we took a close look at the present situation in the global silicon fume market. Continue reading our silica fume industry report to learn more about silica fume market distribution, ứng dụng của nó, and outlook for the future.
Tại sao Silica Fume lại quan trọng?
Silica fume is a fine pozzolanic material produced as a by-product while manufacturing silicon metal or ferrosilicon alloys. It presents one of the key materials used in the manufacture of concrete and refractories, – the material is added to concrete in order to augment its mechanical properties and achieve increased abrasion resistance, better corrosive strength, and superior sulphate resistance. The addition of silica fume also reduces the permeability of the concrete mixture and improves its durability to a certain extent.
Silica fume is a truly versatile material that can be used to produce nearly all grades of concrete. Hơn nữa, it significantly improves the high-temperature performance and strength of refractories. In addition to being used in concretes, xi măng, and refractories, silica fume finds applications in the water glass industry and rubber industry.
The Present Situation in the Silica Fume Industry
Trong những năm gần đây, the demand for densified silica fume has experienced extensive growth.
Silica fume finds its main use in concrete production: khi thêm vào bê tông, the material effectively enhances concrete’s durability and mechanical properties. Như vậy, the rapid growth of the silica fume industry can be attributed to the product’s high strength, quality, and massive resistance to erosion when applied to the construction and building industries.
Hôm nay, silica fume is commonly used in marine structure construction, xây dựng công trình, nuclear plant construction, oil and gas well grouting, and the construction of chemical production facilities. Hơn nữa, it presents excellent material for bridges, metro lines, and rapid-rise structures.
Cuối cùng, the growing demand for silicon in the electricity sector is another driving force on the market, as silica fume production is directly related to silicone manufacturing.

China and the United States
The United States and China are calculated to be the next major silica fume producers. The two countries are expected to retain a significant market share, as the government’s servicing and infrastructure spending increase in the coming years.
Nhập khẩu chất mài mòn cao cấp của Hà Nam & Công ty xuất khẩu, Ltd (HSA) remains among the leading providers of silica fume in the Chinese market, with significant export output to large multinational corporations in the United States, Canada, Nga, Middle-East, và nhiều hơn nữa.
Asia-Pacific and Latin America
The demand for silica fume is also expected to grow in economies in the Asia Pacific and the Latin American regions. Emerging economies like Brazil, Ấn Độ, Malaysia, and Indonesia are expected to augment the demand for silica fume due to rapid urbanization and industrialization to support their demand for silica fume.
Ứng dụng Silica Fume
We have also segmented and ranked the global silica fume market into several categories, based on the application sector. Such categories include building construction, marine structure construction, oil and gas well grouting, chemical production facilities construction, nuclear power plant construction, và những người khác.
- Building Construction (35%-40%)
The use of silica fume in concrete is one of the key emerging trends driving the global silica fume market.
Due to physical and chemical properties specific to silica fumes, such as a highly reactive nature and large surface area, the material is most widely used as a pozzolan in concrete applications. These properties allow silica fume to be used in mammoth construction structures, where silica fume is added to concrete in the required proportion.
When talking about applications of silica fume to concrete, it is worth mentioning that Henan Superior Abrasives Import & Công ty xuất khẩu, Ltd. also remains the premium source of high-performance silica fume products for concrete and refractory industries.
- Marine Sector (20%-30%)
The second-largest end-user of silica fume is the marine sector. Due to its anti-permeable and anti-abrasive characteristics, silica fume is used along with concrete for the construction of bridges, ports, and shipyards in order to increase the resistance to the aggressive salt environment.
- Ngành công nghiệp dầu mỏ và khí đốt (10%-15%)
The oil and gas industry is the third-largest consumer of silica fume.
Due to its efficient provision of durability to concrete, silica fume is effectively utilized in the construction of pipelines for the easy flow of gas and lubricants in boring and drilling wells.
Silica fume is also used extensively in both primary oil well grouting and secondary grouting, as the ability of silica fume to decrease the permeability of the grout slows or even stops gas leakage from the well.
- Others (Fertilizers, Cao su) (10%-20%)
The rest of the silica fume market share is comprised of other industries, such as fertilizers and rubber production.
When used in fertilizers, silica fume effectively aids in the pelletizing process. Rubber industries also consume silica fume, as the material improves the tensile strength and elongation of the rubber products.
What to Expect in the Coming Years?
The size of the global Silica Fume market is projected to reach USD 541.5 million by the year 2026, increasing from USD 469.9 triệu trong 2020.
