Crude Kaolin is used to obtain ceramic refractory products and tiles and is especially used in the manufacture or white cement, due to its low iron content.
We have special kaolins and chamottes for the manufacture of refractory products for vaying applications: firebriks, concretes, mortars, asphalts, in the internal lining of steel-making furnaces, in casting ladles, tiling for trucks, and in general, for all those specially-shaped parts, or pieces which are difficult to obtain by normal manufacturating methods. Our products are marketed in the grain sizes which clients need for the different applications mentiones previously.
Our chamotte is purpose-made for the fabrication of extruded stoneware, as well as other pieces of high-quality stoneware due to its great resistance to wear, scratching, sub-zero temperatures and abrasion as well as resistance to chemical corrosion. It is also used in the production of other ceramic articles.
