Ceramic Bentonite

Date:2017-03-09
Ceramic Bentonite is used as plastic filler in ceramics, especially after sintering need high brightness products. The rheological characteristics & the expandable plaster of the ceramic bentonite increase plasticity & strength of the ceramic plaster and stabilize the water suspension colloid in the ceramic plaster. Also, it could offer high adhesive strength and bending resistance for the finished ceramic products. Ceramic bentonite could be used as plasticizer and thickener in ceramic glaze to offer strength, plasticity and high adhesiveness for ceramic glaze and support objects.
