Zirconium silicate (Zircotech®) is used in the production of glazes & uses as a opacifier in ceramic & sanitary ware industries where a high level of whiteness and covering power is required. It provides finer texture and higher brightness into the product. We also produces zirconium silicate flour uses in the ceramic industry (for the production of frits), and in other industrial fields CLASSIC MICROTECH has stood out in the market for its high quality of zirconium silicate, marketed under the brand name of Zircotech®, a quality guaranteed by the use of the highest grades of Zircon sand procure from Australia & South Africa and the most modern processing technologies..

Product Overview

Zircon is a naturally occurring mineral and its composition depends on the geological history of the parent deposit. In its raw state, zircon sand is found associated with other minerals, e.g. rutile and ilmenite. Zircon is separated from these minerals using special ore dressing techniques. When it arrives at the plants of CLASSIC MICROTECH PVT LTD it is processed and milled to a variety of particle sizes by a number of different production techniques.

The extensive Zircotech® range of zircon products manufactured by CLASSIC MICROTECH PVT LTD is well established and are the world leaders in milled zircon products.

Our reputation for quality products has been acquired by many years research, development and customer involvement. CLASSIC MICROTECH PVT LTD is able to source the best quality raw materials for its products and offers great flexibility in supply by having manufacturing sites in seven countries.
