Description

Calcium Hydroxide CAS NO 1305-62-0 is a versatile inorganic compound, also known as slaked lime, widely recognized for its strong alkaline properties and reactivity. It serves as a critical reagent and processing aid across numerous industrial sectors, valued for its ability to neutralize acids, precipitate impurities, and modify pH. Key industries that rely on this essential chemical include water treatment, construction, food processing, and chemical manufacturing.

Application

• Water & Wastewater Treatment: For pH adjustment, softening, and as a flocculant to remove impurities.
• Construction & Building Materials: A key component in plasters, mortars, and whitewash, and for soil stabilization.
• Chemical Manufacturing: As a precursor for calcium-based chemicals and in the production of bleaching powder.
• Food Industry (FCC Grade): Used as a processing aid, pH regulator, and firming agent (e.g., in pickling, sugar refining).
• Environmental Applications: For flue gas desulfurization (FGD) to remove SO2 from exhaust streams.
• Pulp & Paper Industry: In the kraft process for pulp digestion and causticizing.
• Agriculture: As a soil amendment to correct acidity and improve crop yields.
• Pharmaceutical & Personal Care: Used in certain dental cements and depilatory creams.
