Main Component Of Siliphos Polyphosphate

The main raw materials of silicon phosphorus crystal production are: phosphoric acid, calcium hydroxide, sodium carbonate, this article mainly introduces the main components of silicon phosphorus crystal, detailed explanation you look down:

1.Phosphoric acid: phosphoric acid or orthophosphate, chemical formula H3PO4, molecular weight of 97.994, is a common inorganic acid, is a medium strong acid. It is obtained by dissolving phosphorus pentoxide in hot water. Phosphoric acid is obtained industrially by treating apatite with sulfuric acid. Phosphoric acid delixes easily in air. Heat will lose water to pyrophosphoric acid, and further water loss to metaphosphate. Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as rust inhibitor, food additive, dental and orthopaedic surgery, EDIC etchant, electrolyte, flux, dispersant, industrial etchant, fertilizer raw material and component household cleaning products. Also used as a chemical agent, phosphate is a nutrient for all life forms.

2. Calcium hydroxide, which is commonly known as lime, calcium hydroxide, inorganic compounds, chemical formula Ca(OH)2, commonly known as hydrated lime or slaked lime. Is a white powdery solid, adding water, in two layers, the upper aqueous solution is called clarified lime water, the lower suspension is called lime milk or lime slurry. The upper clear lime water can test carbon dioxide, and the lower turbid liquid lime milk is a building material. Calcium hydroxide is a binary medium strong base (calcium hydroxide is considered to be a strong base in the middle school stage, but in fact it can not completely ionize in water, so it is considered to be a medium strong base in university textbooks), has the universality of alkali, and has a corrosive effect on skin and fabric. Calcium hydroxide is widely used in industry. It is commonly used as a building material, but also used as a fungicide and chemical raw materials.

3.Sodium carbonate: that is, we commonly known as, alkali; Sodium carbonate [497-19-8] (Na2CO3), molecular weight 105.99. The purity of the chemical is more than 99.5% (mass fraction), also known as soda ash, but it is classified as salt, not alkali. Also known as soda or soda ash in international trade. It is an important organic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in domestic washing, acid neutralization and food processing.
