Studies on zircon-dolomite system for refractory application

Mohapatra, I (2014) Studies on zircon-dolomite system for refractory application. BTech thesis.



Zircon (ZrSiO4) and Dolomite (CaMg(CO3)2) are used as raw materials for preparation of porous refractory aggregates. Different compositions e.g. Zircon : Dolomite (Z:D) ratio 1:1, 2:5 and 1:3 (molar ratio) are chosen and the mixtures are reaction sintered in the temperature range 1150oC- 1300oC. Phase evolution as a function of temperature was studied in detail. It was found that the phases present in the sintered product differs by the presences of secondary phase – Ca2SiO4 or Ca3Mg(SiO2)2 - depending on the Zircon dolomite ratio starting mixtures. Apparent Porosity, Bulk Density and Diametral Tensile Strength of the sintered samples has also been measured.
