About Ca Hydroxide

Calcium Hydroxide 97%+ Grade

"Calcium Hydroxide", having CAS-No: 1305-62-0, and traditionally being called hydrated lime or slaked lime, is an inorganic compound with the chemical formula as Ca(OH)₂. It is free flowing super fine super white powder, free from grits & other contaminations and is obtained when calcium oxide (quicklime) is "slaked" with water, to form "Hydrated Lime". Calcium Hydroxide is used in a wide variety of traditional & emerging applications, because of its chemical & physical properties. These are high quality optimum products, compliant to various compendiums, being diligently processed under good manufacturing practices. These products are free from all known allergens and do not contain any prohibitory or toxic chemicals or non-kosher ingredients. The usual shelf life of the product is three to six months from the date of manufacturing of batch. This grade of Calcium Hydroxide shall be having minimum Assay Content of 98%+ as Ca(OH)₂.

Versatile Industrial Applications

Calcium Hydroxide is utilized in a wide range of industries, including water treatment, chemical manufacturing, agriculture, and construction. Its strong alkalinity (pH 12.4 for a 1% solution) provides effective pH control, making it essential in neutralizing acidic environments and enhancing product quality. The fine particle size ensures excellent reactivity and dispersion for various processes.

Product Stability and Storage

This high-purity inorganic base remains stable under typical storage conditions but reacts readily with carbon dioxide in the air, forming calcium carbonate. To preserve its quality and shelf life of 12 months, it should be stored in a cool, dry place within tightly sealed containers, away from acids and excess moisture. Proper storage safeguards against degradation and maintains product performance.

Safe Handling and Packaging Options

Calcium Hydroxide is supplied in robust HDPE bags or jumbo bags to prevent moisture infiltration and physical contamination. Although classified as non-poisonous, it can cause irritation to the skin and eyes, making the use of protective gear essential during handling. Its packaging ensures safe transportation and meets industrial specifications for quality and security.

FAQs of Ca Hydroxide:

Q: How should Calcium Hydroxide be stored to maintain its quality?

A: Calcium Hydroxide should be stored in a cool, dry place with its container tightly closed to prevent it from reacting with moisture or carbon dioxide in the air, which can reduce its effectiveness and shelf life.

Q: What are the main industrial applications of Calcium Hydroxide?

A: This compound is primarily used in water treatment, chemical manufacturing, agriculture, construction, and for pH control due to its strong alkalinity and reactivity.

Q: When does Calcium Hydroxide lose stability or react?

A: While stable under normal storage conditions, Calcium Hydroxide reacts with acids, carbon dioxide from the atmosphere, and moisture, potentially leading to reduced efficacy or conversion to calcium carbonate.

Q: Where is Calcium Hydroxide commonly used?

A: It is commonly used in industrial plants, laboratories, agricultural fields, water treatment facilities, and construction sites across India and globally for diverse processes.

Q: What safety measures are required for handling Calcium Hydroxide?

A: Protective gloves, goggles, and clothing are recommended during handling to avoid skin or eye irritation. Ensure adequate ventilation and avoid inhalation of dust.

Q: How is Calcium Hydroxide beneficial in water treatment?

A: It helps adjust pH, precipitate impurities, and facilitate the removal of heavy metals and organic compounds, enhancing water quality in treatment plants.

Q: What process should be followed for safe disposal of Calcium Hydroxide?

A: Dispose of according to local environmental regulations. Avoid releasing it into drains and waterways; neutralize with acidic substances if permitted before disposal.
