Research of Raw Material Resources of Uzbekistan for Obtaining High-Aluminium Mass

The chemical and mineralogical compositions, physical and chemical characteristics, and phase transformation processes occurring at various stages of roasting (1300-1500 C) of kaolins and aluminacontaining waste were studied.It has been established that firing is accompanied by phase transformations of clayey raw materials, as a result of which new formations occur in the form of mullite minerals.It has been shown that enriched kaolins from the Angren deposit (AK-30 and AKF-78) and waste from the Shurtan gas chemical complex are suitable for developing the composition of high-alumina ceramic and refractory materials.
