Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpetre (or saltpeter in the US). [5] Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of traditional gunpowder (black powder). [6]
A saltpetre works or nitrary [1] is a place of production of potassium nitrate or saltpetre used primarily for the manufacture of gunpowder. The saltpeter occurs naturally in certain places like the "Caves of Salnitre" ( Collbató ) known since the Neolithic.
For instance, power grades of black powder, unsuitable for use in firearms but adequate for blasting rock in quarrying operations, are called blasting powder rather than gunpowder with standard proportions of 70% nitrate, 14% charcoal, and 16% sulfur; blasting powder may be made with the cheaper sodium nitrate substituted for potassium nitrate ...
The powder has occasionally been used as a synonym for Serpentine powder, which it physically resembles. [2] 'Mill meal' powder is a mixture of potassium nitrate, charcoal and sulfur in the correct proportions (75% potassium nitrate:15% charcoal:10% sulfur) which has been ball-milled to mix it intimately. It is used in the same way as ...
Although all firearm propellants are generally called powder, [1] the term gunpowder originally described mixtures of charcoal and sulfur with potassium nitrate as an oxidizing agent. [ 2 ] : 133, 137 By the 20th century these early propellants were largely replaced by smokeless powder of nitrocellulose or similarly nitrated organic compounds .
One’s biological age, which measures the body’s physiological state, may help predict who is at risk for developing colon polyps, a known risk factor for colorectal cancer.
It’s often used in select foods to give it a red color. Despite its wide use in certain foods in the U.S., it’s controversial and banned in some forms in this country. Why is red dye No. 3 bad?
The oxidizer most often used in the preparation of sugar motors is potassium nitrate (KNO 3). Other oxidizers can be used as well, such as sodium and calcium nitrates as well as mixtures of sodium and potassium nitrate. [7] KNO 3 can be acquired through purchasing a granular "stump remover" from stores that carry garden supplies. Other rarely ...
