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 pH (10% Solution): 3.0 - 4.0 Chemical Composition & Purity: AlO (Aluminum Oxide): 15-18% SO (Sulfate Content): 50-55% FeO (Iron Oxide) (For Non-Ferric Alum): Max 0.01% Water Insoluble Matter: Max 0.1% Moisture Content: Max 5% Purity: Min 99% Microbiological Standards (For Food & Cosmetic Grade Alum): Total Plate Count: Max 10,000 CFU/g Yeast & Mold: Max 100 CFU/g Coliforms:
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) Odor: Odorless Taste: Astringent and slightly sweet Mesh Size: 80-200 mesh (as per requirement) Solubility: Fully soluble in water Insoluble in alcohol pH (10% Solution): 3.0 - 4.5 Chemical Composition & Purity: AlO (Aluminum Oxide): 15-18% SO(Sulfate Content): 50-55% FeO (Iron Oxide) (For Non-Ferric Alum): Max 0.01% Water Insoluble Matter: Max 0.1% Moisture Content: Max 5% Purity: Min 99% Microbiological Standards (For Food & Cosmetic Grade Alum Powder): Total Plate Count: Max 10,000 CFU/g Yeast & Mold: Max 100 CFU/g Coliforms:

Ferric alum, also called as Aluminum Sulphate or Ferric Ammonium Sulphate or Iron Alum and has a melting point of 100 C. Ferric alum is basically a less pure form of Aluminum Sulphate. When Bauxite and Sulphur Acid are cooked at a certain condition, leading to the formulation of Ferric Alum. It can also be prepared by the crystallization of Ferric Sulphate and Ammonium Sulphate. Its appearance is light violet in color and comes in various forms such as Powder, Lumps, Slabs and Crystal. It is also available in liquid form. Alum is a weak oxidizing agent and being paramagnetic and acidic in nature, it's toxic towards microorganisms. Alum is ideal to prevent rust and been highly soluble in water helps in algae controlling too. Alum can be used in various industries from Chemical to Textile Industry, Automobile Industry to Iron and Steel Industry and even as an etching agent in production of electronic items. Alum can also be applied in several Laboratory such as of Biochemical Analysis, Organic Synthesis, Agri Products and Petrochemicals. Lower grades of alum are used in Paper Industry for loading and sizing purposes. Alum is a primary coagulant for waste water treatment. Jyoti Chemical supplied Alum is free from impurities and is processed through superior quality of raw ingredients. We offer you exactly as per your specified demand of your industrialized sector with the accurate chemical composition. Our offered product is strictly as per the norms set by the industry and its application. Jyoti Chemical from more than two decades provides you with the best quality of Ferric Alum at the lowest possible price, which are available in Powder, Lumps, Slabs and Crystal.
Non-Ferric Alum is a better and purer form of Aluminum Sulphate. It is made up of Aluminum Trihydrate with a chemical formula Al2(SO4)3. It is a white crystalline solid color. And when in anhydrous form it becomes color less. Non-Ferric Alum is odor less and is non-toxic and non-combustible. It is available in powder or solid form and is multifaceted compound. It has wet tensile strength, preventing moisture from damaging the compound. The major difference between Non-Ferric Alum and Ferric Alum is that Ferric Alum is made up of Bauxite as the raw material, whereas Non-Ferric Alum is made up of Aluminum Trihydrate. Slabs can also be made up from Non-Ferric Alum when the raw material is processed under suitable conditions, with Sulphuric Acid. Being non-toxic and soluble in water makes it vital chemical in many industries, thought its insoluble in ethanol. Non-Ferric Alum is used for wastewater treatment and purification of drinking water. It also finds its application in various industries like Medicine, Pharmaceutical and Cosmetics Industry, Paper and Pulp Industry, Oil and Petroleum and Dyeing Industry and even in Textile Industry. Jyoti Chemical offered Alum has a superior quality with a precise composition. We strictly adhere to the industrial norms and gives you customized and moisture proof packing options. Jyoti Chemical provides you with all the grades and types of Non-Ferric Alum, available in Powder, Slabs or Lumps Form.
