Low Porosity Refractory Fire Clay Grain For Sagger / Kiln Furniture

3-1mm Grain Size Calcined Flint Clay Calcined Kaolin 45% For Sagger And Kiln Furniture

1. Calcined Flint Clay Introduction

Flint Clay is a high quality hard refractory clay. The raw ore is gray and gray black, with fine structure and high hardness. It is not dispersed in water and has low plasticity. It's formed by the calcination of the pyrogemite ore at high temperature. The content of Al2O3 in the calcined pyrogem is about 44%, and the content of Fe2O3 is not more than 2%.Stable composition, uniform texture, compact structure, low water absorption, shell shaped section, white, used to produce high quality clay refractory.
