Calcium HydroxideCalcium Hydroxide: Formula, Properties, Uses, Molar Mass, Safety & Where to BuyCalcium Hydroxide

Introduction: What is Calcium Hydroxide?

Calcium hydroxide, slaked or hydrated lime, is an inorganic compound with the Calcium Hydroxide Calcium Hydroxide chemical formula Ca(OH)₂. Calcium hydroxide has many names, including builders’ lime, caustic lime, slaked lime, cal, and pickling lime. It is used in various applications, including food preparation, where it has been identified as E number E526.

Calcium Hydroxide adopts a polymeric structure similar to magnesium hydroxide (brucite structure). The compound has two hydroxide ions (OH^–) for each ion of calcium (Ca2⁺).

The compound’s density is approximately 2.211 g/cm³ in solid form. It has a melting point of 580 °C (1,076 °F; 853 K), at which it loses water and decomposes. 

For industries looking for a reliable calcium hydroxide supplier or planning to buy calcium hydroxide, understanding its properties and applications is essential. Many businesses also search for calcium hydroxide manufacturers or explore options like calcium hydroxide for sale near me and buy calcium hydroxide near me for bulk procurement

Uses of Calcium Hydroxide

Construction Industry: Calcium hydroxide is a significant component of cement, plaster, and mortar for bricks and stones. It is combined with water and sand to make a slurry that resembles a paste. The sand and calcium hydroxide left behind when the water evaporates combine to create a potent adhesive that keeps the bricks or stones together.Many construction companies prefer to buy calcium hydroxide near me to ensure faster supply and reduced logistics costs.

Neutralizing Chemical: Calcium Hydroxide is used as a neutralizing chemical, as it reacts with acids to create water and salt in a double displacement reaction. In streams, this neutralization might take place to lessen the impacts of acid rain or in farm soils to aid plant development. Additionally, it is added to foods to keep them from being overly acidic. Reliable calcium hydroxide manufacturers provide consistent quality required for such chemical reactions.

Industrial Scrubbers: One of the various chemicals used in industrial scrubbers to remove nitrogen and sulfur oxides from exhaust fumes, a consequence of numerous industrial operations, is calcium oxide. The removal of these oxides decreases industrial emissions, which develop acid rain.Choosing the right calcium hydroxide supplier is important for such environmental applications.

Pesticides: Calcium Hydroxide is used in the manufacturing of some pesticides.

Paints and Waterproofing Materials: Calcium Hydroxide is used to produce colors and waterproofing materials.

Additive to Oils and Lubricants: Calcium Hydroxide is an additive to oils and lubricants to improve their flowability.

Rubber and Plastics Production: The manufacturing of rubber and polymers is accelerated by calcium hydroxide.

Calcium Hydroxide Water Treatment: Calcium hydroxide plays a crucial role in calcium hydroxide water treatment, where it helps neutralize acidic water and remove heavy metals.

Calcium Hydroxide Pharmaceutical Uses: Calcium hydroxide is widely used in dental care, root canal treatments, and medical formulations. Due to strict purity requirements in calcium hydroxide pharmaceutical uses, businesses prefer to buy calcium hydroxide only from trusted calcium hydroxide manufacturers.

Is Calcium Hydroxide Bad for You? (Safety Guidelines & Precautions)

Ingestion: Food-grade calcium hydroxide is generally safe for consumption. However, ingesting industrial-grade calcium hydroxide can result in calcium hydroxide poisoning, which can lead to severe injury or death.

Irritation: Calcium hydroxide can irritate the eyes, skin, and upper respiratory system. It may also cause burns and skin vesiculation.

Incompatibilities: Calcium hydroxide can react with certain substances such as maleic anhydride, phosphorus, nitroethane, nitromethane, nitroparaffins, and nitropropane. It may also attack some metals.

Exposure Routes: Exposure to calcium hydroxide can occur through inhalation, ingestion, and skin or eye contact.

Safety Precautions: When working with calcium hydroxide, it is important to prevent skin and eye contact. In case of contact, immediate irrigation or flushing is recommended. Adequate respiratory support should be provided in case of breathing difficulties. Medical attention should be sought in case of ingestion.

When you buy calcium hydroxide, always ensure proper safety guidelines are followed and that it is sourced from a reliable calcium hydroxide supplier.
