In recent years, there has been an increasing focus on sustainability and eco-friendliness in industrial practices, and mica mineral powder fits well into this trend. As a naturally occurring, non-toxic mineral, mica mineral powder is a more environmentally friendly option compared to many synthetic alternatives. It is often used in construction materials, paints, coatings, and other manufacturing processes to replace harmful chemicals, making it an excellent choice for businesses that prioritize eco-friendly practices.
As the demand for pearlescent mica powder increases, especially in cosmetics, it becomes crucial for companies to ensure their supply chains are free from exploitative practices and that the mining operations are carried out in an environmentally responsible manner.
Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.
Artists often utilize mica powder to add depth and texture to their creations. Its reflective quality can amplify the richness of paints, inks, and mediums.
Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.
It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.
The rapid development of new energy vehicles, batteries and other emerging industries also provides a new application scenario for mica products, such as power battery modules and energy storage system of mica cover plate, mica partition, mica monitoring board and composite mica tape and other products, the application of mica provides the industry with a fire safety solution.
In short, there are significant differences between natural mica powder and synthetic mica powder in production methods, color and appearance, performance characteristics, application fields, and price and cost. Synthetic mica powder is superior to natural mica powder in terms of high temperature resistance, transparency, electrical insulation, stability and mechanical properties, while natural mica powder has more advantages in resource acquisition, cost and color. When choosing which type of mica powder to use, you can consider the high temperature resistance of the required material, electrical insulation performance, transparency and color requirements, evaluate the mechanical strength and hardness of the required material, consider chemical stability and other different application scenarios and technical requirements to make a reasonable choice.
