Which mineral is currently used as an industrial substitute for asbestos?

Wollastonite is recognized as a suitable industrial substitute for asbestos due to its unique properties, which are advantageous in various applications. It is a naturally occurring mineral that possesses high heat resistance, chemical stability, and low thermal expansion, making it an ideal material for use in fireproofing and insulation products. Unlike asbestos, which is associated with severe health risks including lung disease and cancers, wollastonite is considered safe for use and does not carry the same negative health implications.

The mineral's fibrous form allows it to be used in similar applications to asbestos, particularly in construction materials, ceramics, and plastics, where it serves as a reinforcing agent or as a filler to enhance durability and performance. The transition to wollastonite not only addresses health concerns but also aligns with the increasing regulations against asbestos use in many countries.
