ACS Reagent Grade KNO3 Purity 99% CAS 7757-79-1 Colorless Crystalline Potassium Nitrate

ACS Reagent Grade KNO3, Purity 99% CAS 7757-79-1 Colorless Crystalline Potassium Nitrate

1. Potassium Nitrate Introduction

Potassium nitrate is an inorganic compound with the chemical formula KNO3. 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. ACS Reagent Grade KNO3 usage:

Reagent grade potassium nitrate refers to a specific quality or purity level of potassium nitrate that is suitable for use in laboratory and analytical applications. Reagent grade chemicals are typically of higher purity compared to commercial or technical grades, as they undergo more stringent quality control measures to ensure consistency and minimal impurities. Analytical reagents for microanalysis of manganese and sodium. 

Reagent grade potassium nitrate is commonly used in various analytical techniques, such as titrations, spectrophotometry, and chemical synthesis in research laboratories, educational institutions, and industrial settings where precise and reliable results are essential. It offers a high degree of chemical integrity and consistency, ensuring accurate and reproducible experimental outcomes.

4. Potassium Nitrate Application Area

4.1. Potassium nitrate can be used as analytical reagents and oxidants, and it is also used for the synthesis of potassium salts and preparation of explosives.
4.2. In the food industry, potassium nitrate can be used as a hair dye, a color protective, antibacterial agent and preservatives, such as pickled meat, which plays an anticorrosive effect in lunch meat.
4.3. Potassium nitrate is a raw material for making black fireworks, such as ore fireworks. In terms of industry, potassium nitrate can be used to make enamel coatings and can be used as a glass clarification agent for manufacturing automotive car light glass shells, optical glass imaging tube glass shells, etc. Potassium nitrate can be used for cigarette paper and so on.
4.4. Potassium industrial potassium is also allowed to be a color rendering agent in China. In meat products, it is restored to potassium nitrite due to the role of bacterial protection. my country's regulations can be used for meat products, the amount of ambassadors is 0.5g, and the residual amount must not exceed 0.03g.
4.5. Potassium nitrate can be used to make matches, ceramic glaze, fertilizer, etc.
4.6. Potassium industrial potassium nitrate is also widely used to strengthen the manufacturing process of glass.
