Coloured Mica: A Guide to this Versatile Material
Mica is a naturally occurring mineral that is widely used in a variety of industries, including cosmetics, paint, electronics, and construction. One of its most popular forms is coloured mica, which offers a range of benefits and uses. In this blog post, we'll take a closer look at what coloured mica is, how it's made, and some of its most popular applications.
What is Coloured Mica?
Coloured mica is simply mica that has been treated with pigments or dyes to produce a wide range of colours. The mica itself is a silicate mineral that forms in flat, flaky layers that can be separated and processed. The resulting sheets of mica are then treated with pigments to produce a range of colours, from deep, rich hues to lighter, brighter shades.
How is Coloured Mica Made?
The process of making coloured mica starts with the extraction of raw mica from mines. The raw mica is then processed to remove impurities and to separate the flaky layers. Once the mica is separated, it is treated with pigments to produce the desired colour.
The pigments used to colour mica are usually inorganic compounds, such as iron oxide, titanium dioxide, and chromium oxide. These pigments are added to the mica in a liquid form and then dried, allowing the pigment to bond with the mica.
Once the coloured mica has been dried, it is then processed further to create a range of particle sizes and shapes, from fine powders to larger flakes. The final product is a versatile material that can be used in a variety of applications.
Applications of Coloured Mica
Coloured mica has a wide range of applications, thanks to its unique combination of physical and optical properties. Some of the most popular applications of coloured mica include:
