Molecular Weight: 132.06

CAS NO.: 7783-28-0

EINECS NO: 231-987-8

Character：White Powder

Purpose:

Diammonium Phosphate is Agricultural Grade Phosphate and Tech Grade Phosphate mainly used as a high concentration nitrogen phosphorus compound fertilizer; Industrial grade is used for impregnating wood and fabrics to increase their durability. It can also be used as a dry powder fire extinguishing agent and phosphorus for fluorescent lamps; It is also used for printing plate making, manufacturing of electronic tubes, ceramics, enamel, etc., and biochemical treatment of wastewater.

Diammonium phosphate (DAP) is a type of fertilizer that contains a high concentration of both nitrogen and phosphorus. Its chemical formula is (NH4)2HPO4. The numbers 18-46-0 on the label of DAP fertilizer indicate the percentage of nitrogen (18%), phosphorus (46%), and potassium (0%) in the fertilizer.

DAP is a common fertilizer used in agriculture because it provides both nitrogen and phosphorus, which are essential nutrients for plant growth. Nitrogen is necessary for the development of leaves and stems, while phosphorus promotes root growth and flower development.

DAP fertilizer is typically applied to the soil before planting or during the early stages of plant growth. It can be used on a variety of crops, including vegetables, fruits, and grains. However, excessive use of DAP fertilizer can lead to soil acidification and nutrient imbalances, which can negatively impact plant growth and yield.

Overall, DAP fertilizer is a popular choice for farmers and gardeners who want to promote healthy plant growth and increase crop yields.

Diammonium phosphate (DAP) is a type of fertilizer that is commonly used in agriculture. It contains nitrogen and phosphorus, two essential nutrients for plant growth. DAP is often used to promote root development, increase crop yields, and enhance plant growth.

In addition to its use in agriculture, DAP is also used as a fire retardant. When mixed with water, it can be sprayed onto surfaces to help prevent fires from spreading. This is because DAP releases ammonia gas when heated, which can help to smother flames and prevent them from spreading

Overall, DAP is a versatile chemical that has a variety of uses in different industries. Its ability to promote plant growth and prevent fires make it an important resource for farmers and firefighters alike.
