Introduction and Fundamental Properties

Talcum powder, a naturally occurring hydrous magnesium silicate (Mg₃Si₄O₁₀(OH)₂), represents a highly versatile industrial mineral characterized by its exceptional physical and chemical properties. This fine white powder exhibits a Mohs hardness of 1, making it the softest known mineral, and demonstrates perfect basal cleavage that contributes to its characteristically greasy texture. The material's unique combination of properties - including chemical inertness, thermal stability, and low electrical conductivity - has led to its widespread adoption across multiple industrial sectors.

Detailed Physical Characterization
