Ceramic Industry
Kaolin has a wide range of applications in the ceramic industry and is commonly used in white tableware, tiles, sanitary ware, insulators and refractories. Kaolin imparts rheological properties, stronger finished product and smooth surface finish; alongside improved optical properties for white ware.Kaolin is becoming more prevalent in porcelain insulation due to its high dielectric strength. Kaolin is used in refractories due to its extremely high fusion point, low water content and high green strength. Ceramics produced with kaolin have a wide variety of uses – primarily as a metal substitute. Ceramics are becoming more prevalent in aerospace due to their refractory strength. Ceramic knives stay sharper longer and have better durability than metal. Toyota has created an all ceramic car engine capable of running at much higher heats. Recently there have also been advances in bio-ceramics that may lead to new and better teeth and bone replacements.
Basically there are three different types of Tiles
- Floor Tile
- Wall Tile
- Vitrified Tile
- Body: The base part of the Tile
- Engobe: Engobe is the first layer above the tile body this gives white colour & Opacity to Wall & Floor Tiles
- Glaze: Glaze is the second layer above the tile body, This provides gloss and Various designs it is also impermeable to Water & Stains
Calcined kaolin usage - Ceramic Tile Industry
Engobe
- Usage: Vitrofine for partial replacement (20 %) of of ZrSiO4
Glaze ( Opaque )
- Usage: Vitrofine for partial replacement (20 %) of of ZrSiO4
- Function: Opacity, Whitness
