Kaolin: An Overview

Kaolin is a stone from which the earth mineral kaolinite is inferred. This one has been utilized for centuries as the foremost additive in porcelain tableware. Today Jagdamba Minerals’ kaolins bring critical properties to a large group of end applications going from paper to paints, rubbers to cosmetics and Pharmaceuticals.

China Clay

Kaolin, or ‘china clay’ as it is ordinarily called, is a hydrated aluminum silicate crystalline mineral framed over a long time by the aqueous disintegration of granite rocks.

Hydrous kaolin is portrayed by its fine particle size, plate-like or lamellar particle shape, and chemical inertness.

Metakaolin is manufactured by the calcination of kaolin to frame a formless pozzolanic white mineral added substance for use in concrete based items.

Calcined Kaolin is an anhydrous aluminum silicate created by warming ultrafine natural kaolin to high temperatures in a furnace. The calcination interaction expands whiteness and hardness, improves electrical properties, and modifies the size and shape of the kaolin particles.

Jagdamba Minerals offers a wide scope of inventive and economical designed kaolin-based solutions for help optimize client execution within businesses as diverse as Agriculture, ceramics, cosmetics, feeds, paper and packaging, paints, pharmaceuticals, plastics, and rubbers.


  • High brightness
  • Non – abrasive
  • Naturally fine particles
  • Refractory, remains white after calcination
  • Weak conductivity (heat and electricity)
  • Hydrophilic and easily dispersed in water
  • Free from impurities
  • Free from impurities
  • Strong decolouring ability
  • Long shelf life


Kaolin is a majority segment for the ceramics industry, where its high fusion temperature and white firing attributes make it especially reasonable for the manufacturing of sanitaryware, tableware, wall, and floor tiles, and refractories.

Utilized in brightening paint formulations, it is a magnificent natural opacifier and partial replacement for titanium dioxide, and ideal for use when high gloss is required.

JM designed kaolins are additionally utilized as multi-utilitarian fillers to improve the performance of rubber.

JM has in-depth knowledge on how kaolin associates with its clients’ end products. Working closely with customers, we will keep on discovering esteem added, kaolin-based solutions to help them improve execution, diminish costs and limit their carbon impression.
