Description

Sodium Phosphate Introduction

Sodium Phosphate is a kind of white crystalline powder with a chemical formula of Na3PO4. It is one of the important product series in the phosphate industry. Due to its special properties, it is widely used in modern industry, agriculture and animal husbandry, petroleum, papermaking, detergents, ceramics, and other fields. Sodium phosphates have many applications in food and water treatment.

Sodium Phosphate Properties

  • Hygroscopic: Some forms, particularly monosodium and disodium phosphates, can absorb moisture from the air.
  • Buffering Capacity: These compounds are often used for their buffering properties in various chemical and biological systems, helping to maintain stable pH levels.
  • Decomposition: On heating, sodium phosphates decompose, releasing water (if hydrated) and leaving a mixture of sodium pyrophosphate and sodium metaphosphate.

Sodium Phosphate Application

  • As a moisture retention agent in the food industry, it is used in canned food, fruit juice drinks, dairy products, meat products, cheese, and beverages.
  • As a quality improver, it has the functions of improving the complex metal ions, pH value, and ionic strength of food, thereby improving the binding force and water-holding capacity of food.
  • Used for the purification of sugar.
  • Water Treatment: Used to prevent the formation of scale and corrosion in boilers and pipelines.
  • Cleaning Agents: In particular, trisodium phosphate is used as a heavy-duty cleaner and degreaser.
