Kaolin's size and dimensional aspects make it a good filler for coatings and other materials [5]. Its small particles help to improve the wettability, smoothness, and durability of these materials. Kaolin chemical structure and element composition give it its white color and other properties.
Kaolinite is a mineral belonging to the group of aluminosilicates. It is commonly referred to as "China Clay" because it was first discovered in Kao-Lin, China. The term kaolin is used to describe a group of relatively common clay minerals dominated by kaolinite and derived primarily from the alteration of alkali feldspar and micas.Kaolin is a white, soft, plastic …

This paper concluded that solids-to-liquid and sodium silicate-to-sodium hydroxide ratios have a significant effect on compressive strength of hardened cement paste. The optimum solids-to-liquid and sodium silicate-to-sodium hydroxide ratios were 0.80 and 0.20, respectively.
One of the primary uses of kaolin is in the paper industry, where it acts as a filler and coating pigment. Kaolin is added to paper pulp to improve its brightness and smoothness, resulting in high-quality paper products. Improving Ink Absorption. Kaolin's ability to enhance ink absorption is crucial for the industry.
