Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:
Types of Mica A Comprehensive Overview
5. Cost Efficiency While it might be tempting to purchase mica flakes based solely on price, opting for a reputable supplier often results in long-term cost savings. Higher-quality mica can lead to fewer defects, reduced returns, and enhanced customer satisfaction, ultimately benefiting the bottom line.
Natural mica powder and synthetic mica powder have differences in production methods, heat resistance and color transparency. As the name suggests, natural mica powder is made from natural mica ore after processing, retaining the original characteristics and composition of the ore. Its main components are SiO2 (about 49%) and Al2O3 (about 30%), while also containing K2O+Na2O (9%-11%) and so on. The synthetic mica powder (such as fluoroglogopicite powder), is the use of a variety of raw materials through high temperature reaction and other chemical methods synthetic, its composition and characteristics can be adjusted and optimized according to the need, the chemical formula is KMg3(AlSi3O10)F2, belongs to the monoclinic crystal system, is a typical layered silicate, relatively single and pure composition. The heat resistance of natural mica powder is generally 500-600℃, and some types, such as phlogopite, can reach 800℃. The heat resistance of synthetic mica powder is more excellent, and it can withstand high temperatures above 1200℃, and the melting point or crystallization temperature is about 1375±5. The transparency of natural mica powder is relatively low, and the color is diverse, including black, yellow, white, gray, green, brown and other colors, and may vary due to different ore types and processing methods. The color of synthetic mica powder is relatively single, usually colorless transparent or white, high whiteness, good optical performance, and high transmittance from ultraviolet to infrared band.
In recent years, the global mica industry has witnessed substantial growth, with significant contributions from leading mica exporters. These exporters have been instrumental in meeting the increasing demand for mica across various sectors, such as cosmetics, electronics, and automotive industries. As a critical component in manufacturing processes, mica's outstanding properties, including its thermal and electrical resistance, lightweight nature, and insulation capabilities, make it indispensable.
