Vitrofine Clay

VITROFINE is a product derived from refined kaolin specially developed from selected raw material blends for specific use in the ceramic industry.

APPLICATION :

VITROFINE is recommended as a partial substitute of Zircosil5 (15-30%) in Matte, Rustic and Glazy Engobe. The high brightness and whiteness of VITROFINE helps to partially replace Zircosil5 in engobe. The fine particle size improves smoothness of Rustic Tile and the high alumina content along with high MOHS value of 7 gives wear, scratch and abrasion resistance to tiles. The low color requirement for dark shades is an added advantage.

GUIDELINES FOR THE USAGE OF VITROFINE:

Along with other raw materials, VITROFINE can be added in the ball mill and normal milling time can be given. It is advisable to start with low percentage of Zirconium substitution (say 20 %). VITROFINE will give better performance in the temperature range of 1120 – 1150 deg C.
