White Crystal Potassium Nitrate Fertilizer KNO3 UN 1486 CAS 7757-79-1

White Crystal Potassium Nitrate Fertilizer, UN 1486 CAS NO 7757-79-1 Nitrato De Potasio

1. Potassium Nitrate Introduction

Potassium nitrate is an inorganic compound with the chemical formula KNO3. It is also known as saltpetre or nitre, is a chemical compound with the formula KNO3. It is a crystalline salt that is typically colorless or white. Potassium nitrate is composed of potassium ions (K+) and nitrate ions (NO3-). It has a molecular weight of approximately 101.1 grams/mol. It is a colorless transparent rhombic crystal or diamond shaped crystal or white powder, odorless, non-toxic, with a salty and refreshing taste. Potassium nitrate is easily soluble in water, soluble in liquid ammonia and glycerol, and insoluble in anhydrous ethanol.

Potassium nitrate is a chlorine-free nitrogen potassium compound fertilizer with high solubility. Its effective components, nitrogen and potassium, can be quickly absorbed by crops without any chemical residue. It can be used as fertilizer and is suitable for vegetables, fruits, and flowers, as well as some chlorine sensitive crops such as potatoes, strawberries, beans, cabbage, lettuce, peanuts, carrots, onions, blueberries, tobacco, apricots, grapefruit, and avocados, etc.

Potassium nitrate is a strong oxidizing agent that can cause combustion and explosion when in contact with organic matter. Therefore, potassium nitrate should be stored in a cool and dry place, away from flames and heat sources. Avoid co storage and mixed transportation with reducing agents, acids, flammable substances, and metal powders.

3. Potassium Nitrate Application Area

3.1.In agriculture, potassium nitrate is commonly used as a fertilizer due to its nitrogen and potassium content. It provides essential nutrients for plant growth and is particularly beneficial for crops that require high levels of potassium, such as fruits and vegetables. It can be applied to soil directly or used in hydroponic systems.

3.2. The Use of Potassium Nitrate in Industry:

Potassium nitrate is both a decolorizing agent and a clarifying agent in the production of glass. It mainly provides potassium element in the production of ceramic frits. Its main function is to reduce the melting temperature, increase the expansion coefficient of the frit, and also help to increase the transparency of the frit. The high-temperature viscosity of potassium element is relatively high, which has the effect of expanding the sintering range of glaze. At the same time, due to the action of its nitrate, it will decompose to produce oxygen at high temperatures, so it also has oxidation effect, which is beneficial for improving the whiteness of the frit. Potassium nitrate plays a role in supplying oxygen in gunpowder. Potassium nitrate can provide sufficient oxygen to support combustion during the combustion process of gunpowder. In addition, potassium nitrate also helps to improve the combustion rate of gunpowder.

3.3. KNO3 for  food preservation:

Potassium nitrate also has applications in the food industry. It is used as a food preservative, especially in meat and cheese products, to inhibit the growth of bacteria and extend the shelf life of these perishable items. However, its use in food preservation is regulated in many countries due to concerns about potential health effects.
