Dehydrated Mica
Calcinated mica, also known as dehydrated mica, is produced by losing some of the crystal water in mica under the condition of high temperature. Our company employs rotary furnace in mica calcination to guarantee minerals heated equably. Huayuan calcinated mica has stable quality, bright colors and improved application performance, especially suitable for industries of building decoration, electrical insulation and special welding.

Mica Flake
Mica Flakes is mica scrap ground into sizes ranging from 2 mesh to 20 mesh. This material is prepared mainly by the means of rotary hammer crushing machine in which the scraps are literally beaten till the required size is achieved.Muscovite mica flake is the most widely used. Not only Muscovite, phlogopite, biotite, synthetic mica also can be ground into flakes.

Mica Pigment
Mica pearl pigment series are classic effect pigments, which consists of treated natural mica flakes coated with a thin layer of metal oxide, such as titanium dioxide or/and iron oxide. Through a combination of transparency, refraction, multiple reflections, particle size and coating thickness, a wide variety of color effects are produced. These color effects are found elsewhere only in nature – silver white, interference and metallic luster effects.

Expanded Vermiculite
The density of vermiculite is 2.4-2.7g/cm3 it begins expend when it is heated over 200℃, becoming the worm-like shape and it can be 15-25times bigger than the original volume,maximum 30 time. When it is rapidly heated to 800℃. This forms the material with low density(100-300㎏/m³), excellent insulation property and good hydroscopicity and ion exchange capacity. Because the vermiculite has a fine air barrier, it has excellent heat preservation performance.

Raw Vermiculite
Vermiculite is a kind of natural, non-toxic, inorganic silicate mineral, whose raw ore looks like mica. Vermiculite is formed by the hydrothermal alteration or weathering of minerals, usually biotite and phlogopite. When heated,it expands like leech. Vermiculite are divided into raw vermiculite and expanded vermiculite by stages, and according to the color, it can be divided into golden vermiculite, silvery white vermiculite, milky white vermiculite.

Kaolin Clay
Kaolin is a kind of non-metallic mineral. It is a kind of clay mainly composed of kaolinite group clay minerals including kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Because it is white and delicate, it is also called Baiyun soil. The pure kaolin is white, delicate and soft with good plasticity and fire resistance.
