Wollastonite and calcite minerals are significant raw materials and are extensively used due to their unique properties. Wollastonite is used in plastics, paint, ceramics, paper, resins, and in construction as a substitution for asbestos due to its chemical stability, thermal resistivity, needle-like shape, and brightness. Calcite is one of …

Wollastonite is used in fire-resistant building products and performs well when used in countertop and tile applications. Enhancing Food Production. Wollastonite in soil provides a source of plant-available silicon and carbon neutral calcium, unlike lime which releases ~30% of its weight as CO2 when it reacts with soil.

Recent field trials and ongoing research show that when wollastonite is applied as a soil amendment, it reduces grub pressure in turfgrass. When grubs come into contact with wollastonite, their soft bodies are lacerated by the tiny needle-like crystals which leads to desiccation and death.

Wollastonite also competes with several nonfibrous minerals or rocks, such as kaolin, mica, and talc, which are added to plastics to increase flexural strength, and such minerals as barite, calcium carbonate, gypsum, and talc, which impart dimensional stability to plastics. In ceramics, wollastonite competes with carbonates,

Wollastonite is predominantly short-needled and, to the naked eye, the bands it forms look dense and sugary. ... Notably, the stoichiometry of the C–S–H gel is like that included in conventional cement hydration. However, the gel carbonates rapidly to eliminate lime and produce calcite and silicate gel, yielding the following overall reaction:

As Franklin and Sterling Hill Wollastonite is almost always associated with calcite, and occasionally with willemite and other fluorescent minerals, specimens are usually quite attractive "under the lamp." At Franklin more than anywhere else, there are many visually distinctive types of Wollastonite that are eagerly sought by collectors.

Wollastonite did not become an important industrial mineral until the 1950s, with growing appreciation of its value in coatings and ceramics during the post-war building boom. Wollastonite is unique among nonmetallic industrial minerals for its combination of white color, acicular (needle-like) crystal shape and alkaline pH.
