 Properties & Uses of Ball Clay

Ball Clay is a fine grained and plastic sedimentary clay, mined and processed (water washed and filter pressed).

The properties of Ball Clay is valued in its high plasticity, dry strength, Green strength, Bonding nature etc. The high plasticity facilitates shaping and finishing of ceramic bodies and high strength allows un-dried clay article to keep their shape and withstand all types of molding, shaping and conveying during manufacture. Hence Ball Clay is recommended for Refractory products, Ceramic Granite Tiles, Glazed Tiles, Table Ware & High Tension Electric Insulators etc.
