Kaoline

Aluminum Silicate Hydroxide
Al2Si2O5(OH)4

                The technical data kaoline

                          (raw ore)

There are plenty of kaolinite in mine field of DFL Minmet refractories Corp. The ore body is stable and has a high quality. Its 340, 000, 000 tons producible reserver provide a reliable resource for deeply processing.

              The technical data of Kaoline

                               (GSK)

The GSK is made by the way of dry process, including de ferrization, superfine, surfacetreatment, and has a well particle distribution. The GSK can be used in rubber and paint oil as filling material, in sanitary ceramics, building ceramics, glazed material, high voltage electric porcelain, refractory material and polymerized aluminum as fundamental compounding receipt material.

            The technical data of superfine calcined Kaoline

                                       (GSCK)

The GSCK is made by the process of well fragmentizing, calcining and surface treating.Because of its high lightness, well particle distribution and strong cover capacity, the GSCK can be used in many industries such as rubber, oil paint, cable, plastics, refine ceramics, paper, paint, fireproof coating material and abrasive resistant material, etc.
