Sillimanite and Californite Physical Properties

Sillimanite and Californite Chemical Formula

While comparing Sillimanite and Californite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Sillimanite and Californite chemical formula.
