Product Introduction:

Phosphoric acid, also known as orthophosphoric acid (molecular architectural formula H3PO4), is a colorless transparent thick fluid or orthorhombic crystal in pure form, odorless as well as sour in preference. Soluble in water, soluble in ethanol.

Is a common not natural acid, is a solid acid. Its level of acidity is weaker than solid acids such as sulfuric acid, hydrochloric acid and also nitric acid, yet more powerful than weak acids such as acetic acid, boric acid as well as carbonic acid.

When phosphoric acid responds with sodium carbonate, different acid salts can be formed at different PH. It can aggravate the skin and also create inflammation and damages the body tissue.

Typically, commercially readily available phosphoric acid is a viscous, concentrated option with a H3PO4 web content of 82%. The viscosity of the solution is high due to the visibility of hydrogen bonds in the solution.

As a seasoned phosphoric acid supplier, Look Chemical has understood different production procedures. The manufacturing facility is furnished with first-rate production tools to guarantee a secure supply of products. Click here to learn more about Look Chemical.

Nature and Specifications:

Product Packaging



It is a medium-strong acid with a condensation point (cold point) of 21 ° C. When the temperature is less than this temperature, hemihydrate (ice) crystals will certainly speed up. Crystal characteristics: high concentration, high pureness, high crystallinity.

High boiling factor acid, can be miscible with water in any type of ratio, when the boiling point is 213 ℃ (loss of 1/2 water), it will certainly generate pyrophosphoric acid. When warmed to 300 ℃, it becomes metaphosphoric acid.

Phosphoric acid crystallization is a physical adjustment rather than a chemical adjustment. Its chemical properties will certainly not be transformed by crystallization, as well as its top quality will certainly not be impacted by condensation. As long as it is melted by temperature level or watered down by heating water, it can still be used normally.

Product Usage:

Phosphoric acid is a fundamental chemical basic material, widely made use of in phosphate, fertilizer, preservative, feed, cleaning, electronics, fire resistants and other industries. The primary application locations are as complies with:

  • Fertilizer Market
    • Phosphoric acid is an important intermediate product in the manufacturing of chemical plant foods as well as is made use of to generate high-concentration phosphate fertilizers and also substance fertilizers.
  • Metal Sector
    • Deals with steel surfaces to develop insoluble phosphate movies on steel surfaces to protect them from rust. Blended with nitric acid as a chemical polishing representative to enhance the finish of metal surfaces.
    • Preparation of electrolytic sprucing up fluid and chemical sprucing up liquid, sprucing up of light weight aluminum products.
    • It is made use of to generate refractory mud as well as improve the life of steelmaking heater.
  • Repaint and Pigment Market
    • It is used as a resources for the production of phosphates.
    • Phosphates are developed in the paint pigment market as pigments with special features. As flame resistant, anti-rust, anti-corrosion, radiation resistance, anti-bacterial, luminescent as well as various other ingredients, it is developed into finishings.
    • Desiccant for the manufacturing of dyes and intermediates. Printing is utilized to develop a cleaning agent for removing discolorations from offset color printing plates.
    • For the manufacturing of steel anti-rust paint.
  • Used as Chemical Raw Product
    • Resources for numerous phosphates as well as phosphate esters utilized in the production of soaps, detergents, chemicals, phosphorus-containing flame resistants and also water therapy agents.
    • Fertilizing the matchstick can make the scorched matchstick not ash and end up being charcoal, which is more secure to use.
    • In market, focused sulfuric acid is generally responded with calcium phosphate to prepare phosphoric acid, as well as the calcium sulfate precipitate that is a little soluble in water is filtered off, and also the gotten filtrate is phosphoric acid service.
  • Pharmaceutical Market
    • It is used to manufacture sodium glycerophosphate and also iron phosphate, and also to readjust the pH in the manufacture of penicillin; it is used to produce zinc phosphate as a glue for dental fillings.
  • Various Other Usages
    • Phosphoric acid can also be made use of to make feed quality calcium hydrogen phosphate, acid manganese phosphate, potassium pyrophosphate, and so on.
    • Rubber is used as coagulant for slurry as well as resources for production of inorganic binder; it is utilized as acid flavor agent in food sector.
