Calcium carbonate appears as white, odorless powder or colorless crystals. Practically insoluble in water. Occurs extensive in rocks world-wide. Ground calcium carbonate results directly from the mining of limestone. The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product form. Precipitated calcium carbonate is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a by-product of the Solvay process (which is used to make sodium carbonate). Precipitated calcium carbonate is purer than ground calcium carbonate and has different handling properties.
Calcium carbonate is naturally found in rock and mineral formations. Calcium carbonate is slightly water soluble, and is thereby leached into natural water systems, resulting in “hard” water. Limestone and chalk are comprised of calcium carbonate– as are coral reefs. The mineral is typically procured via mining and quarrying. Calcium carbonate exists as limestone, chalk, and dolomite, and typically includes impurities like clay.
CaCO3 has different applications in various industries and is most widely used as fillers. in the past, this material was used for construction and shelter building.
Lauded among many industries for its use, calcium carbonate is a key player in the following industries:
- Healthcare
- Oil
- Plastic/Rubber
- Cement
- Glass
- Steel
- Paper
- Construction
1. Calcium Carbonate in the Garden
The foremost ingredient in garden lime (commonly referred to as agricultural lime) that is responsible for sedating harmful soil acidity is calcium carbonate. The compound also improves the quality of the soil for surrounding plant life. Calcium carbonate (as you may have guessed) bestows plants with a (1) healthy source of calcium, (2) pH balancing properties, (3) increases water retention ability within acidic soils, and (4) encourages absorption of crucial nutrients including nitrogen, potassium, and phosphorus despite being rooted in acidic soils.
2. Calcium Carbonate’s Role in Construction & Cement Making
Did you know you walk on calcium carbonate every day? Calcium carbonate is a keystone building material in the construction industry, largely leveraged in cement production. The substance is typically utilized in its limestone state for these purposes. In addition to cement constructs, calcium carbonate is relied upon heavily in laying the foundation for road construction. The substance is frequently used to help soil firm up, allowing for the erection of bridges, homes, and towering edifices.
Large clusters of calcium carbonate are typically used to satisfy a need for considerable aggregates; reacting with soil, lime helps clay to cement (almost literally) and create tighter compounds. Additionally, the firming effect of calcium carbonate allows large construction vehicles to more easily traverse construction worksites.
Expanding upon calcium carbonate’s inclusion in cement production, the principal form utilized in cement preparation is limestone. Cement at its essence is comprised of calcium silicates and calcium sulfate.
3. Living Organisms Need Calcium Carbonate for Bone & Teeth Formation
And you’re one of them! Did you know your teeth and bones are made from a healthy dose of calcium carbonate? Likewise, plants and animals use the mineral to construct their skeletons and shells. Animals most notable for this include snails, coral, pearls, turtles, and other shelled creatures. Calcium carbonate is again redeposited into the soil upon the death of plants and animals hosting the substance.
Factoid: Egg shells are mostly comprised of calcium carbonate.
