Wollastonite has a low sintering temperature (approximately 991-1196°C), comparable to that of most natural frits. Friction: Due to its physical structure and non-hazardous properties, wollastonite is used as a reinforcing additive in many friction applications. Wollastonite has partially or at some places fully replaced asbestoses, milled ...

La wollastonite possède un clivage parfait dans deux directions et a une fracture irrégulière à écailleuse. Du fait de ses propriétés de clivage particulières, ses cristaux prennent généralement des formes lamellaires ou aciculaires (en forme d'aiguille). Ces fibres appartiennent à la famille des fibres minérales naturelles.
