• Resumen

  • Sarah Gibbons, Keith Nuthall, Raghavendra Verma and John Pagni Most, if not all, of the wollastonite market is comprised of ground wollastonite in the form of powders that are added to ceramics (frits, sanitaryware, and tile), friction products (primarily brake linings), metallurgical applications (flux and conditioner), paint (architectural and industrial paints), plastics and rubber markets (thermoplastic and thermoset resins and elastomer compounds) and some miscellaneous uses (including adhesives, concrete, glass, and sealants). Transparency Market Research (see below) meanwhile described wollastonite as having “several exclusive characteristics” which make it “one of the most versatile functional filler and reinforcement agents.” Since 2001, its report said, ceramic applications have accounted for more than 50% of wollastonite sales worldwide, followed by polymers at around 25%, and coatings at nearly 15%. [...]Transparency Market Research projects a three-to-fourfold increase in demand for wollastonite by 2050 in Latin America, Africa, the Middle East, and Asia.This carbon reduction potential is recognized worldwide, with the Indian Minerals Yearbook 2017, from the Indian Bureau of Mines, highlighting as “a new development with very large potential” the use of wollastonite as a sequestration mineral for carbon dioxide. According to Indian Bureau of Mines, in the financial year ended March 2017, Indian exports of wollastonite were 16,699 tonnes, mainly to Belgium (53%), Japan (25%), Germany (12%) and Turkey (3%).
