4、Method for determination of calcium oxide and magnesium oxide contents in manganese ores--Atomic absorption spectrophotometric method
8、Heating this chemical compound drives off carbon dioxide gas, leaving calcium oxide.
12、Non-pollution roasting technology by using sodium carbonate, calcium oxide, red mud and lime mud as roasting additives for extraction of vanadium from siliceous navajoite was studied.
2、The gas is fed back over the calcium oxide.
7、Distribution of free-calcium oxide in converter slags and its stabilization
13、On a test rig of flue gas humidification and desulfurization an experimental study was conducted of the desulfurization performance of calcium oxide activated by steam humidification.
5、a substance (such as calcium oxide) that absorbs water and is used to remove moisture.
11、"desiccant:a substance, such as calcium oxide or silica gel, that has a high affinity for water and is used as a drying agent."
6、Quicklime, slaked lime and hydraulic lime, other than calcium oxide and hydroxide of heading No. 28.25.
1、Management of calcium oxide deliquescence process
14、The siliceous impurities in the ore are removed by reaction with the calcium oxide that is formed when the limestone is heated, CaO + SiO2--Ca-SiO3.
3、The thermal decomposition of calcium carbonate produces calcium oxide and carbon dioxide.
10、If rice was grown in saline-alkali soil, the best result was shown when the seeds were dressed with calcium oxide.
9、A reducing agent converts the calcium sulfate to calcium oxide, which is then removed, by reintrainment into the flue gas steam using soot blowers or sonic horns.
