The use of mica in paper
Mica Sericite can be used as a filler in paper products by adding it to the paper pulp before it is formed into sheets. The mica will help to improve the strength and opacity of the paper, as well as reduce the amount of ink needed to print on it. To use Mica Sericite as a filler, it should be added to the paper pulp in a ratio of 1 part Mica to 10 parts pulp. The Mica should be ground into a fine powder before being added to the pulp. Once the Mica is added, the pulp should be mixed thoroughly to ensure that the Mica is evenly distributed throughout the paper. After the paper is formed into sheets, it should be dried and pressed to ensure that the Mica is evenly distributed throughout the paper
.The most common micron size for Mica Sericite used in the paper industry is 10-20 microns
