What is the classification of white asbestos?

White asbestos, primarily recognized as chrysotile, belongs to the serpentine group of minerals. This classification is based on its crystalline structure, which is characterized by soft, flexible fibers that can be easily separated. Serpentine minerals, including chrysotile, have a layered structure that contributes to their distinct physical properties, such as high tensile strength and resistance to heat.

Chrysotile is the most common form of asbestos and represents approximately 95% of the asbestos used in various applications. Its serpentine structure plays a crucial role in its applications and hazardous implications, as it can lead to respiratory problems when inhaled due to its fibrous form.

In contrast, the amphibole group includes other forms of asbestos like amosite and crocidolite, which have a different crystal structure and chemical composition. Other classifications, such as fibrous or metallic minerals, do not accurately describe white asbestos, as the defining characteristics of chrysotile align it specifically with the serpentine group.
