Calcium carbide (CaC2) is a pivotal inorganic compound known for its industrial form as gray-black block-like material, often displaying purple or gray cross-sections. When exposed to water, it undergoes an energetic reaction, producing acetylene gas and releasing heat. Primarily, it's employed for two key purposes: as a source of acetylene gas with applications in welding, cutting, and fuel, and as a raw material in organic synthesis for chemicals like vinyl chloride and synthetic resins.

Calcium carbide is an inorganic compound, white crystal, industrial products are gray black blocks, cross-section purple or gray. It reacts violently with water, forming acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding and so on. It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown. 2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell. 3. It can produce acetylene gas when met water, it can burn when meets fire. 4.The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%). 1.The main raw material for producing acetylene gas. 2.Cutting and welding for metal material. synthesize polyvinyl chloride(PVC). 4.Fruit catalyst. 5.The basic material for organic synthesis and calcium cyanamide 6.Reacting with water to bring about ethine. 7. Reacting with nitrogen to product lime nitrogen. 8.The desulfurizer in steel industry.

STPP is known as Sodium Tripolyphosphate. It is commonly used in the manufacture of synthetic detergents, water treatment, and other sectors such as ceramics, food and beverage, paint and varnish, etc. It is a white molecular mineral and is used as a binder, stabilizer and sequestrant. We get our STPP mineral from several regions of Rajasthan in India. STPP has several applications in the food and beverage industry. Cake mixtures, meringues, juices, hams, peas, lima beans, cured pork, sausages, and algin sweets all contain this ingredient. Within the ceramic and enamel industry, STPP mineral is used to achieve a fluid paste or a well-dispersed solution which further optimizes the manufacturing process. Sodium triphosphate is a solubilizing binder found in powder detergents, automatic dishwashing powder/tablets, and other cleaning solutions. It is particularly effective in treating water hardness by inactivating the mineral ions and keeping them securely in the solution. It permits surfactants to perform to their maximum extent by fighting water hardness. It also functions as a pH buffer and prevents soil from resettling on the garments. This makes it the most perfect mineral in the laundry detergents, dishwashing powder and in the tanning of leather. Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), is an inorganic compound with formula Na5P3O10. Furthermore, it is also popularly used in the paper and coatings industry to remove the pitch spots. They are created by a kind of gum present in the wood pulp which can cover the whole surface and create dents on the surface of the paper. This natural mineral is magmatic in nature and has a high phosphorus concentration and very low heavy metal levels. As a result, our STPP mineral has a high purity level which enhances the performance of whatever end-product it is utilised in.
