The sand itself is dug out and leached for nitrates which were then converted to potassium nitrate using potash, as above. It is an alkali metal nitrate because it is an ionic salt of potassium ions K + ions and nitrate ions NO 3 − . Its density in the solid, crystalline form is 1.984 grams per cubic centimetre. It's important to note, however, that potassium is very reactive with air and water. Compare Products: Select up to 4 products. Traditionally, guano was the source used in Laos for the manufacture of gunpowder for Bang Fai rockets. What are the physical and chemical properties of potassium nitrate (KNO3)? [36], Potassium nitrate is used in fertilizers as a source of nitrogen and potassium – two of the macronutrients for plants. [27] It can also be heated to several hundred degrees to be used for niter bluing, which is less durable than other forms of protective oxidation, but allows for specific and often beautiful coloration of steel parts, such as screws, pins, and other small parts of firearms.
