Thermal decomposition of calcium carbonate | Resource | …
The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate This experiment can be carried out conveniently in groups of two or three and takes about 40–45 minutes.
Kurt J. Lesker Company | Calcium Ca Pieces Evaporation …
Calcium oxide (CaO) will evaporate at an appreciable rate at ~1,700 C. We have reported success evaporating calcium out of our EVCH12 heater with an EVC5AO crucible. Great care must be taken when installing the heater to prevent the outer shields from becoming warped which can cause a short in the heater, causing the welded joints to fail.
