Alum is a group of hydrated double sulfates of aluminum and other elements such as potassium or ammonium. It is widely used in water treatment, food processing, cosmetics, and pharmaceuticals. Below are the general specifications for different types of alum:
Common Types of Alum:
1. Potassium Alum (KAl(SO)12O) - Used in water purification, food, and cosmetics
2. Ammonium Alum (NHAl(SO)12HO) - Used in industrial and water treatment applications
3. Sodium Alum (NaAl(SO)12HO) - Used in food processing and baking powder
4. Ferric Alum (FeAl(SO)12HO) - Used in water treatment and paper manufacturing
Physical Properties:
Appearance: White, transparent crystalline solid or powder
Color: White or colorless (can be slightly yellow in ferric alum)
Odor: Odorless
Taste: Astringent and slightly sweet
Solubility: Soluble in water, insoluble in alcohol
Alum powder is a fine, white crystalline powder derived from aluminum sulfate compounds. It is widely used in water purification, food processing cosmetics, pharmaceuticals, and industrial applications. Below are the general specifications for alum powder:
Types of Alum Powder:
1. Potassium Alum Powder (KAl(SO)12HO) - Used in food, water treatment, and cosmetics
2. Ammonium Alum Powder (NHAl(SO)·12HO) - Used in industrial and textile applications
3. Sodium Alum Powder (NaAl(SO)12HO)-Used in baking powder and food processing
4. Ferric Alum Powder (FeAl(SO)12HO)- Used in water treatment and paper industries
Physical Properties:
Appearance: Fine, free-flowing powder
Color: White or colorless (ferric alum may appear yellowish)
