In this study, samples from Zefreh dolomite mine were characterized by Xray diffraction and microscopic study. Dolomite samples were heated up to 1700#186;C to produce doloma. Zircon and zirconia were used for preparation of dolomite zirconia refractories. Samples containing different contents of zirconia and zircon were heated up to 1600 #186;C.
#0183;#32;The local dolomite was supplied by dolomite quarry from Perlis, while kaolin was collected from mine in Simpang Pulai, Perak. Fig. 1 shows the images of dolomite and kaolin used in this study. The specific gravity of dolomite and kaolin is g/cm 3 and g/cm 3, and kaolin were grounded into powder for mineral characterization using planetary ball milling with a
Dolomite has a large amounts of MgO and is an important raw materials for steel, iron and refractory industries. In this paper thermal behavior of Zefreh dolomite at various temperatures was studied by differential thermal analysis (DTA), Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT IR) and powder Xray diffraction (XRD) techniques.

Abstract. Dolomite has a large amounts of MgO and is an important raw materials for steel, iron and refractory industries. In this paper thermal behavior of Zefreh dolomite at various temperatures was studied by differential thermal analysis (DTA), Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT IR) and powder Xray diffraction (XRD) techniques.
In this study, samples from Zefreh dolomite mine were characterized by Xray diffraction and microscopic study. Dolomite samples were heated up to 1700 o C to produce doloma. Zircon and zirconia were used for preparation of dolomite zirconia refractories.
