Wollastonite is a non-metallic mineral with good electrical and physicochemical properties. It can be widely used in ceramics, metallurgy, plastics, rubber, papermaking and other industries. According to its particle size and composition, wollastonite products can be divided into wollastonite powder, ultra-fine wollastonite powder, needle shaped wollastonite powder, modified wollastonite powder, etc., with different uses.
Wollastonite powder: particle size <43 μ m. It is mainly used for ceramic raw materials and glazes, paper-making fillers, rubber and plastic fillers, welding electrodes, metallurgical protective slag, paint fillers, etc;
Wollastonite ultrafine powder: particle size <10 μ m. It is mainly used as filler for paint, plastic rubber, cable, etc;
Wollastonite needle like powder (wollastonite powder with high aspect ratio): aspect ratio ≥ 10:1, mainly used for paint pigments, reinforcing agents of plastic rubber, fibrous fillers of friction materials of steam clutch brakes, etc;
Modified wollastonite powder: it is a product coated with silane and other surfactants. It is mainly used for composites of cables, plastic rubber and other materials, with strong reinforcement function.
According to the wollastonite Market Research Report issued by CMRC Zhongyan Century Consulting, the apparent consumption of wollastonite products in China has increased year by year since 2016, reaching about 467000 tons in 2020, of which the consumption of ceramic industry accounts for the highest, about 55%; Followed by metallurgy, welding electrodes, coatings, glass fiber and other industries, the demand for wollastonite accounts for more than 5%; The demand for wollastonite in engineering plastics and paper industry is relatively low at this stage.
Domestic demand of wollastonite downstream in 2020 (10000 tons) (data source: CMRC)
In the future, domestic wollastonite market demand will mainly depend on downstream application fields and scene development. Wollastonite production enterprises can focus on promoting the substitution of wollastonite products for existing products in papermaking, coating, welding electrode, glass fiber and other industries.
Taking the papermaking industry as an example, the main purpose of wollastonite application in the papermaking industry is to increase the opacity and whiteness of paper, and to replace some plant fibers. At present, the proportion of products added with wollastonite in the domestic paper industry is less than 1%. However, with the continuous improvement of the requirements of the national environmental protection policies, the proportion of wollastonite used as the main filling material of raw pulp in the paper industry will continue to increase in the future. If the output data of 127million tons of domestic paper industry in 2020 is taken as the benchmark, assuming that the proportion of wollastonite used in the future paper industry will increase to 2%, the potential market demand for wollastonite will reach about 800000 tons, and the paper industry will also become the largest user of wollastonite products in the future.
