Question:

What standard does a stone for burning lime need to burn to reach the standard?

What standard does a stone for burning lime need to burn to reach the standard?

Answer:

Calcite is the main component of carbonate rocks. Limestone with a calcium content of more than 98%
Most of the time is made by high temperature calcination of limestone lime, CaCO3 (the main component of the stone, then the product is dissolved) Yu Shuizhong, generation of lime water (the main component of the chemical reaction equation of calcium hydroxide) for CaCO3=CaO+CO2 (high temperature conditions) CaO+H2O=Ca (OH) 2 solution
If a high stone content of CaCO3, you can separate the extracted CaCO3.CaCO3= by this stone (calcined CaO+CO2; CaO) is calces, immediately joined the H2O reaction of Ca (OH) 2, the reaction is exothermic, and does not need heating.Ca (OH) 2 for lime.
