The common characteristics of mica group minerals are: layered silicate minerals, monoclinic crystal system, a few trigonal crystal system, the crystals are pseudo-hexagonal columnar, plate and sheet; The aggregate is scaly and foliaceous. It has a set of extremely complete cleavage, along which it is easy to peel into sheets. Therefore, the shape of mica is usually regarded as sheet.

While mica processing plants play a significant role in industrial production, it is essential to address the environmental and ethical concerns associated with mica mining. Many mica deposits are located in developing countries, where mining can lead to detrimental environmental impacts and social issues, including child labor. Therefore, initiatives to promote sustainable practices and ethical sourcing within the mica supply chain are crucial.

1. Thermal Stability One of the most notable attributes of mica is its ability to withstand high temperatures without degradation. This property is particularly advantageous in automotive applications, as components are often subjected to extreme conditions.
