Calcium Carbonate Light
Calcium Carbonate Light is a finely ground, low bulk density natural mineral composed primarily of calcium carbonate (CaCO₃). Compared to standard grades, it has a lower density and larger particle size distribution, making it suitable for applications where light weight and high brightness are important. This form is extensively used as a filler and extender in industries such as plastics, paints, rubber, paper, adhesives, and construction materials to improve opacity, brightness, and texture, while maintaining low weight and cost efficiency. Its chemical inertness and whiteness provide functional and aesthetic advantages across formulations.
Calcium Chloride Dihydrate
Calcium Chloride Dihydrate (CaCl₂·2H₂O) is a hydrated form of calcium chloride, appearing as white crystalline granules or flakes containing two molecules of water of crystallization. It is highly soluble in water and exhibits strong hygroscopic and deliquescent properties. This compound is widely used in industrial, pharmaceutical, food, and agricultural sectors due to its moisture absorption, de-icing, dust control, and calcium supplementation capabilities. Compared to anhydrous calcium chloride, the dihydrate form has lower hygroscopicity but is easier to handle and store.
Calcium Hydroxide Hydrated Lime
Calcium Hydroxide Hydrated Lime, commonly known as Hydrated Lime or Slaked Lime, is an inorganic compound with the chemical formula Ca(OH)â‚‚. It appears as a white, odorless, powder or crystalline solid. It is produced by treating quicklime (calcium oxide) with water in a process called slaking. Calcium Hydroxide is moderately soluble in water, forming a strongly alkaline solution known as limewater. It is widely used in construction, environmental, chemical, agricultural, and water treatment applications due to its caustic, neutralizing, and flocculating properties.
Calcium Nitrate
Calcium Nitrate is a highly soluble, white crystalline salt composed of calcium and nitrate ions. It is commonly available as a tetrahydrate (Ca(NO₃)₂·4H₂O). Known for its excellent solubility in water, calcium nitrate is widely used as a fertilizer providing both calcium and nitrogen to plants. It improves soil structure, enhances nutrient uptake, and prevents disorders such as blossom-end rot in fruits. Beyond agriculture, calcium nitrate serves in wastewater treatment, concrete acceleration, and industrial chemical processes.
Calcium Sulphate
 Calcium Sulphate is an inorganic compound composed of calcium, sulfur, and oxygen, commonly found in two forms: dihydrate (gypsum, CaSO4·2H2O) and anhydrous (CaSO4). It appears as a white or off-white crystalline powder or granules with low solubility in water. Calcium Sulphate is widely used in construction, agriculture, pharmaceuticals, food industry, and various industrial applications. It acts as a filler, hardening agent, and drying agent due to its physical and chemical properties. The dihydrate form (gypsum) is notable for use in plaster and cement, while the anhydrous form is often used as a drying agent and in refractory materials.
Lactic Acid
Lactic Acid is a colorless to pale yellow, viscous liquid with a mild acidic odor. It is an organic acid naturally produced by fermentation and widely used in industrial, pharmaceutical, cosmetic, and food applications. The 80% concentration provides a balance of potency and ease of handling, making it suitable for pH adjustment, preservation, and chemical synthesis. Lactic acid is biodegradable, non-toxic, and valued for its multifunctionality including antimicrobial properties and chelation abilities.
Master Cem Is3000
