Investigation of Zefreh Dolomite as a Refractory Raw Material and Preparation of Dolomite Zirconia Bricks

Writers : Tahmasbi Poor, Kh.; Poormoafi,M.
Refference : Geosciences Scientific Quarterly Journal,No.:67,P.:116
Publishing Year : 1387

Abstract :

In this study, samples from Zefreh dolomite mine were characterized by X-ray diffraction and microscopic study. Dolomite samples were heated up to 1700ºC 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 ºC. Apparent porosity, bulk density, X-ray diffraction, cold compressive strength, hydration resistance tests and SEM studies were carried out on the fired samples. Results show that samples containing
zirconia have higher quality than samples containing zircon without additives.
