Dolomite Refractory
INTRODUCTION Dolomite is a calcium and magnesium double carbonate (CaCO3, MgCO3). It is a key raw material in the iron and steel, ferroalloys, glass, alloy steels, and fertilizer industries, among other industries. There are also dolomite chip flooring tiles accessible. Dolomite brick has a number of characteristics that make it an excellent refractory lining for […]
The metal and its alloys
The metal and its alloys Primary magnesium is available in grades of 99.90, 99.95, and 99.98 percent, but, in practice, grades 99.95 and 99.98 have only limited use in the uranium and nuclear industries. For bulk use, grades 99.90 and 99.80 are supplied. Metallurgical applications By far the greatest use of magnesium is as an […]
Lime and Dolime kiln
A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate). The chemical equation for this reaction is: In Lime CaCO3 + heat → CaO + CO2 In Dolomite Ca(Mg)CO3 + heat → CaO + MgO + CO2 This reaction takes place at 900-1100°C (at which temperature the partial […]
