Description
M107 Fine-grained White Mica or Sericite Mica Powder has an amazing particle size of 7μm (D50) and astonishing whiteness greater than 83. Because of these properties, it is of cosmetic grade.
Features
Our cosmetic-grade sericite boasts high natural whiteness, low levels of heavy metals, low α-quartz content (<1%), a matte finish, silky skin feel, superior powder pressing performance, and small particle size (D50=4.5~5.5μm), making it an excellent substitute for talc. It is utilized by numerous well-known brands and has received consistent positive feedback from both domestic and international customers.
❶ Self-owned mine
We own 0.4565 square kilometers of mining rights for the Ma'anshan sericite mine in Mianning County. Initial proven reserves of 10 million tonnes, mostly mud-like output, high whiteness, small natural grain size. Through agitation and dispersion, it is very easy to separate impurity minerals, and the sericite products obtained are of extremely high purity and are very rare and highly sought-after globally.
❷ Patented Technology
The application of patented technology can separate and remove impurities, and reduce the content of heavy metals.
❸ Silicon Reduction Technology
Can reduce α-quartz content to less than 1%.The obtained high-quality sericite powder with ultra-low α-quartz is exported to Japan, Korea, USA, France, and other countries, and is highly praised by customers.
❹ High Natural Whiteness, Small Natural Particle Size and Thin Flake.
The products have a natural whiteness greater than 85, with a natural average particle size (unprocessed) of approximately D50 = 6.5 micrometers, and upon thorough delamination, the thickness is about 100-200nm.
