Calcium carbonate, or CaCO3, comprises more than 4% of the earths crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity. Calcium carbonate is one of the most useful and versatile materials known to man.
Uses
Paper, Plastics, Paints, and Coatings: Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler and due to its special white color - as a coating pigment. In the paper industry it is valued worldwide for its high brightness and light scattering characteristics, and is used as an inexpensive filler to make bright opaque paper. Filler is used at the wet-end of paper making machines, and calcium carbonate filler allows for the paper to be bright and smooth. As an extender, calcium carbonate can represent as much as 30% by weight in paints. Calcium carbonate also is used widely as a filler in adhesives, and sealants.
Personal Health and Food Production: Calcium carbonate is used widely as an effective dietary calcium supplement, antacid, phosphate binder, or base material for medicinal tablets. It also is found on many grocery store shelves in products such as baking powder, toothpaste, dry-mix dessert mixes, dough, and wine. Calcium carbonate is the active ingredient in agricultural lime, and is used in animal feed. Calcium carbonate also benefits the environment through water and waste treatment.
Building Materials and Construction: Calcium carbonate is critical to the construction industry, both as a building material in its own right (e.g. marble), and as an ingredient of cement. It contributes to the making of mortar used in bonding bricks, concrete blocks, stones, roofing shingles, rubber compounds, and tiles. Calcium carbonate decomposes to form carbon dioxide and lime, an important material in making steel, glass, and paper. Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water

Sulfuric acid is a key substance in the chemical industry. It is most commonly used in fertilizer manufacture, but is also important in mineral processing, oil refining, wastewater processing, and chemical synthesis
Muriate of potash, also known as potassium chloride contains 60% potash. Potash is essential for plant growth and quality. It plays a vital role in the production of proteins and sugars. It also protects against draught by maintaining plants water content which in turn is a benefit for photosynthesis as leaves maintain their shape and vigor.
Nitric Acid is a strong acid with chemical formula HNO3. It is also known as the spirit of niter and aqua fortis. In its pure form, it is colourless but as it gets older it turns into a yellow cast. This colour appears due to the decomposition of Nitric acid to oxides of nitrogen and water. It is highly corrosive and toxic. It causes severe skin burn. It reacts with hydroxides, metals, and oxides to form nitrate salts.
We can supply calcium carbonate in all sizes starting from powder to stones with very high Purity.
Calcium carbonate powder is used in several applications like paints, PVC Pipes, paper& printing, cables, ruber&tires, adhesives, non-woven fabrics, and film.
Ammonium sulphate is a very important fertilizer for any kind of soil that's high in pH and needs a little bit of sulfates to work against the high calcium or the high pH.
Ammonium sulfate is a very important fertilizer for any kind of soil that's high in pH and needs a few sulfates to work against the high calcium or the high pH.
• Ammonium sulfate is used for plants that are producing any kind of oil, like soybeans, sunflower, etc…
• Ammonium sulfate is better in spring in the main application of pre-sowing cultivation, which allows even distribution of fertilizer in the field.
Triple superphosphate (TSP) was one of the first high-analysis phosphorus (P) fertilizers that became widely used in the 20th century.
Technically, it is known as calcium dihydrogen phosphate and as monocalcium phosphate, [Ca(H2PO4)2 .H2O]. Despite its excellent history as a P source, its use has declined as other P fertilizers have become more popular
The concept of TSP production is relatively simple. Manufacturers make nongranular TSP typically by reacting finely ground phosphate rock with liquid phosphoric acid in a cone-type mixer. Granular TSP is made similarly, but the resulting slurry is sprayed as a coating onto small particles to build granules of the desired size. The product from both production methods then cures for several weeks as the chemical reactions are slowly completed. The chemistry and process of the reaction will vary somewhat depending on the properties of the phosphate rock.
Agricultural use
TSP has several agronomic advantages that made it such a popular P source for many years. It has the highest P content of dry fertilizers that don’t contain nitrogen (N). Over 90 percent of the total P in TSP is water soluble, so it becomes rapidly available for plant uptake. As soil moisture dissolves the granule, the concentrated soil solution becomes acidic. TSP also contains 15 percent calcium (Ca), providing an additional plant nutrient.
AVAIL FOR GRANULAR PHOSPHATE FERTILIZERS is designed to be sprayed on granular phosphate fertilizers
(MAP, DAP and other granular phosphate fertilizers), to sequester antagonistic metals in the soil surrounding the fertilizer granule, reduce tie-up of phosphate, and make phosphate more available to the plant.
AVAIL increases phosphate availability through all stages of plant growth, including the early development period crucial for increasing yield potential. AVAIL is water soluble, biodegradable, and nontoxic.
When Undisturbed, Avail For Granular Phosphate Fertilizers Inhibits Phosphate Fixation And May Also Be Used With Fall Fertilizer Applications.
Avail For Granular Phosphate Fertilizers Is A Non-plant Food Ingredient, And Not Recommended For Use As A Fertilizer Substitute.
