کلسیم کربنات سبک

Calcium carbonate is a naturally occurring chemical compound with the formula CaCO₃. It is a white, odorless powder or crystalline substance found in rocks such as limestone, marble, and chalk. It is commonly used in many industries due to its abundance and versatile properties.
🏭⚗️ Production
Calcium carbonate is typically obtained by mining natural sources like limestone or marble. It can also be produced synthetically by combining calcium oxide with carbon dioxide.
🧪 Applications
Calcium carbonate is widely used as a filler material in paper, plastics, paints, and rubber. It is also used in agriculture to neutralize acidic soil, in the food industry as a calcium supplement, and in construction as a building material (e.g., cement and lime).
⚠️ Safety
Calcium carbonate is generally recognized as safe. However, inhalation of fine calcium carbonate dust may irritate the respiratory system. Proper handling and protective measures are recommended when working with powdered forms.
