Calcium cyanamide, with the chemical formula CaCN2 and CAS registry number 156-62-7, is a compound known for its applications in agriculture and industry. This white crystalline solid is characterized by its calcium and cyanamide functional groups. It is commonly used as a fertilizer, providing ...
Calcium–oxygen (Ca–O2) batteries can theoretically afford high capacity by the reduction of O2 to calcium oxide compounds (CaOx) at low cost1,2,3,4,5. Yet, a rechargeable Ca–O2 battery that operates at room temperature has not been achieved because the CaOx/O2 chemistry typically involv...
DefinitionChEBI: Calcium oxide is a member of the class of calcium oxides of calcium and oxygen in a 1:1 ratio. It has a role as a fertilizer. Production MethodsCalcium oxide is commercially obtained from limestone. The carbonate is roasted in a shaft or rotary kiln at temperatures below 1...
