I. What is calcium carbonate?

1. Definition

Calcium carbonate (CaCO3) is a chemical inorganic compound. The usage of chalk, which is a type of CaCO3, makes it one of the most well-known compounds that people come into contact with first. It is located in the earth's crust. It may be found in a variety of materials, including marble, limestone, and more. Despite coming in many forms, they are chemically equivalent and only physically differ from one another.

2. Properties

Calcium carbonate has several notable properties, including:

- Chemical composition: Calcium carbonate is a chemical compound with the formula CaCO3.

- Appearance: Calcium carbonate appears as a white, odorless, tasteless powder.

- Solubility: Calcium carbonate is insoluble in water but dissolves poorly.

- Reactivity: Calcium carbonate is a basic compound and reacts with acids to neutralize them.

- Decomposition: When heated, calcium carbonate breaks down, releasing carbon dioxide and calcium oxide (calcination of calcium carbonate and thermal breakdown of calcium carbonate are both conceivable at temperatures above 800°C)

- Hardness: Calcium carbonate has a relatively high hardness and is used as a filler in various industrial applications to improve the hardness and durability of products such as plastics, paints, and rubber.

- Neutralization: Calcium carbonate is commonly used as a neutralizing agent in agriculture, manufacturing, and medicine. It is added to soil to neutralize soil acidity, improving the growth of plants. In medicine, calcium carbonate is used as an antacid to treat indigestion, acid reflux, and heartburn.

- Versatility: Calcium carbonate is widely used in various industries, including construction, agriculture, and manufacturing. In construction, it is used as a building material and in the production of lime. In manufacturing, it is used as a filler, whitening agent, and neutralizing agent in products such as toothpaste, paper, and foods. Also, there are various calcium carbonate uses in plastic nowadays.

- Reactivity: Calcium carbonate reacts with acids to neutralize them, making it a useful component in various chemical processes. It is also used in the production of lime, which is used as a reagent in environmental and chemical processes.

3. Types of calcium carbonate

There are three polymorphic forms of calcium carbonate: calcite, aragonite, and vaterite. - Calcite: This is the least soluble and most stable mineral. It is a mineral that helps make rocks, and sedimentary, metamorphic, and igneous rocks frequently include it. Sedimentary rocks like marble and limestone frequently include calcite. In addition to many other uses, it is widely employed in the production of building materials and the treatment of agricultural land. - Argonite: Compared to calcite, it is less stable and more soluble. Aragonite is a rarer form of calcium carbonate that is found in marine environments and hot springs. Physical and biological factors, such as precipitation from freshwater and marine habitats, contribute to its formation. In addition to providing nutrients to marine life, argonite also keeps pH levels at their ideal range. It is applied to clean up wastewater that contains contaminants like lead, cobalt, and zinc. Filler masterbatch made from CaCO3 and LDPE, LLDPE, MDPE, MPE and HDPE resins can be applied to LDPE, HDPE bag blowing products, helping to improve physical performance and properties.

Calcium carbonate resin fillers bring advantages to the end product such as:

- Reducing the cost of raw materials

- Increasing product hardness

- Improving impact resistance by falling weight method

- Improving tear resistance

- Increasing air resistance for packaging products

- Increasing the shape of packaging products

The applications of calcium carbonate filler materials in packaging products are agricultural mulch, food wraps in supermarkets, shopping bags, heavy product bags...
