Calcined Kaolin

VM Calcined Kaolin

Kaolin, also known as China Clay, offers unique advantages due to its composition. It is composed of the mineral kaolinite, a hydrated aluminosilicate. Its diverse applications across various industries stem from its unique physical and chemical properties. Shape, particle size, color, softness, and non-abrasiveness are key physical properties. Chemical properties, such as relatively low base exchange capacity and relative insolubility, are governing factors in many uses. Vasu Minechem offers a variety of kaolins calcined at medium to high temperatures depending on the end applications for its global customers. These kaolins boast favorable properties like natural whiteness, fine particle size, non-abrasiveness, and chemical stability. Notably, kaolin is a soft white clay and an essential ingredient in the manufacture of china and porcelain. It also finds wide use in the production of paper, rubber, paint, and many other products. The name "kaolin" originates from Kao-ling, a hill in China where it was mined for centuries.
