Özet

Suitability of the Agla-Koycegiz dunites for manufacturing olivine bricks was assessed by addition of the Kumas fine sintered magnesia in 10, 20, 30 and 40% proportions. The average value of MgO for Agla dunites is around of 46wt.%. Magnesium sulphate was used as a chemical binder and gets good resistance to the mixes before firing. High Fe2O3 content of the Agla dunites help to sintering process. Addition of the sintered magnesia and magnesium sulphate to the mixes increases MgO/SiO2 ratio. Phase composition, bulk density and cold crushing results at 1625degreesC show that these mixes are not mature ceramic.
