Talc is a phyllosilicate mineral composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2.
Talc is a hydrated magnesium silicate. Each talc deposit has a unique morphology and mineralogy, but all talcs exhibit the following unique properties: softness, water repellency, chemical inertness, platyness, and an affinity for organic substances.
These properties make talc a highly prized multi-functional filler and process enabler in an array of applications from plastics to paper, ceramics to paint.
