Definition
Aluminum sulfate (Al2(SO4)3) is a white crystalline solid that appears yellowish or gray when impure. It is highly soluble in water and has a molecular weight of 342.15 g/mol. Widely used in water treatment, paper manufacturing, and the chemical industry, it is also known as papermaker's alum or alum cake.
Physical & Chemical Properties
- Appearance: White crystalline powder
- Density: 2.672 g/cm3
- Melting Point: Decomposes at 770°C
- Solubility: Highly soluble in water (31.2 g/100 mL at 20°C)
- pH: Acidic in aqueous solutions (pH ~2.5 for 1% solution)
- Reactivity: Reacts with bases to form hydroxides and with carbonates to release CO2
Production Methods
1. Bauxite Process: Bauxite ore is treated with H2SO4, filtered, and crystallized.
2. Clay Process: Clay is roasted, reacted with H2SO4, and purified via crystallization.
3. Aluminum Hydroxide: Reaction with H2SO4 followed by evaporation and cooling.
Storage Guidelines
- Store in a cool, dry, well-ventilated area away from incompatible materials (e.g., alkalis, metals).
- Keep containers tightly sealed to prevent moisture absorption.
- Use corrosion-resistant equipment for handling solutions.
Market Information
- Global Production: Over 3 million tons annually
- Key Producers: China, the United States, Europe
- Price Range: $200-$400 per metric ton (varies by grade and region)
- Growth Drivers: Water treatment demand, paper recycling, and construction applications
Downstream Applications
