Is wollastonite hazardous like asbestos?

No, wollastonite is chemically distinct from asbestos minerals. However, as with any fine particulate dust, inhalation should be controlled in industrial settings.

What industries use wollastonite the most?

The primary users are the ceramics industry (for tiles, sanitaryware), the plastics/paint industry (as a filler and reinforcement), and metallurgy (as a slag conditioner).

How is wollastonite pronounced?

In both British and American English, it is pronounced /ˈwʊləstəˌnaɪt/, with the main stress on the first syllable.

Can wollastonite be used in construction?

Indirectly, yes. It is a component in some specialty building materials like friction products (brake pads), certain cement formulations, and fire-resistant boards.

My Flashcards

Definition

Meaning

A white to gray calcium silicate mineral.

A mineral used commercially in ceramics, plastics, and as a filler; formed by metamorphism of limestone.

Linguistics

Semantic Notes

Exclusively refers to a specific mineralogical entity. The name is eponymous (from W.H. Wollaston).

Dialectal Variation

Examples

By CEFR Level

The mineral wollastonite is white.

Wollastonite is sometimes used in ceramic tiles to improve strength.
The geologist identified wollastonite in the rock sample.

Acicular wollastonite is prized as a reinforcing agent in thermoplastic composites due to its high aspect ratio.
The skarn deposit yielded significant quantities of high-purity wollastonite suitable for industrial applications.
