NOP Agricultural Grade Fertilizer Potassium Nitrate K2O 46.2% N 13.5% HS CODE 28342110

Description 

POTASSIUM NITRATE is a white to dirty gray crystalline solid. Water soluble. Noncombustible, but accelerates the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in solid propellants, explosives, and fertilizers.

Etymology

Potassium nitrate, because of its early and global use and production, has many names.

The Greeks used the term nitron, which was Latinised to nitrum or nitrium, while earlier Hebrews and Egyptians

used words with the consonants n-t-r, which leads some to speculate that the Latin term is closer to the original

than the Greek term. Middle English styled it niter. Old French had niter. By the 15th century, Europeans referred to

it as saltpeter and later as nitrate of potash, as the chemistry of the compound was more fully understood.

The Arabs called it "Chinese snow" (Arabic: ثلج الصين‎ thalj al-ṣīn). It was called "Chinese salt" by the

Iranians/Persians or "salt from Chinese salt marshes" (Persian: نمک شوره چيني‎‎ namak shūra chīnī).

Specification

Application 

1. Nitric acid production

Historically, nitric acid was produced by combining sulfuric acid with nitrates such as saltpeter. In modern times this is reversed: nitrates are produced from nitric acid produced via the Ostwald process.

2. Oxidizer

The most famous use of potassium nitrate is probably as the oxidizer in black powder.

3. Fertilizer 

Potassium nitrate is used in fertilizers as a source of nitrogen and potassium – two of the macronutrients for plants. When used by itself, it has an NPK rating of 13-0-44.

4. Other uses

· Electrolyte in a salt bridge

· Active ingredient of condensed aerosol fire suppression systems. When burned with the free radicals of a fire's flame, it produces potassium carbonate.

· Works as an aluminum cleaner.

· Component (usually about 98%) of some tree stump removal products. It accelerates the natural decomposition of the stump by supplying nitrogen for the fungi attacking the wood of the stump.

· In heat treatment of metals as a medium temperature molten salt bath, usually in combination with sodium nitrite. A similar bath is used to produce a durable blue/black finish typically seen on firearms. Its oxidizing quality, water solubility, and low cost make it an ideal short-term rust inhibitor.

· To induce the flowering of mango trees in the Philippines.

· Thermal storage medium in power generation systems. Sodium and potassium nitrate salts are stored in a molten state with the solar energy collected by the heliostats at the Gemasolar Thermosolar Plant. Ternary salts, with the addition of calcium nitrate or lithium nitrate, have been found to improve the heat storage capacity in the molten salts.

· As a source of potassium ions for exchange with sodium ions in chemically strengthened glass.
