Product Introduction
Calcium hydroxide (Calcium Hydroxide) is a common inorganic alkaline compound, appearing as a white powder or colorless crystals with strong alkalinity. It is produced by the reaction of calcium oxide (quicklime) with water and is widely used in water treatment, building materials, environmental remediation, the food industry, and pharmaceutical applications.
Due to its low cost, stability, and environmental friendliness, calcium hydroxide is one of the most widely used inorganic chemical raw materials worldwide.

❓ FAQ（Frequently Asked Questions）
Q1: What are the main applications of Calcium Hydroxide?
👉 Water treatment, construction, flue gas desulfurization, food additives, and agriculture.
Q2: Is Calcium Hydroxide food-grade?
👉 Yes, we supply both industrial-grade and food-grade (E526) calcium hydroxide.
Q3: How is Calcium Hydroxide different from Calcium Oxide?
👉 Calcium Hydroxide (Ca(OH)₂) is produced by adding water to Calcium Oxide (CaO). It is less caustic and easier to handle.
Q4: Can Calcium Hydroxide be used for environmental protection?
👉 Yes, it is widely used in flue gas desulfurization (FGD) and acid wastewater neutralization.
Q5: What is the shelf life?
👉 12 months under proper storage conditions.
