Where can I buy quicklime?

Some chemical stores or building materials stores in the market sell quicklime.

Calcium lime is usually made from natural rocks with calcium carbonate as the main component by high temperature calcination, which can be decomposed into carbon dioxide and calcium oxide. All natural rocks with calcium carbonate as the main component, such as limestone, chalk and dolomite limestone, can be used to produce lime. In coastal areas, shells are used as raw materials, and shell ash is made by burning, which is used as quicklime.

Characters:

Generally, quicklime contains quicklime, which solidifies slowly. If the lime slurry is solidified after hardening, it will expand and crack due to the expansion caused by solidification. In order to eliminate the harm of quicklime, lime should be "aged" for about 2 weeks after curing.

Appearance is white (or gray, brown and white), amorphous, absorbing water and carbon dioxide in the air. Calcium oxide reacts with water to generate calcium hydroxide and give off heat. Soluble in acidic water, insoluble in alcohol. It belongs to inorganic alkaline corrosive substances, and the national hazard code is 95006. When lime reacts with water, it will be heated to a high temperature above 100℃.
