Nitrate IonPotassium Nitrate Solutions are moderate to highly concentrated liquid solutions of Potassium Nitrate. They are an excellent source of Potassium Nitrate for applications requiring solubilized Compound Solutions Packaging, Bulk Quantity materials. American Elements can prepare dissolved homogenous solutions at customer specified concentrations or to the maximum stoichiometric concentration. Packaging is available in 55 gallon drums, smaller units and larger liquid totes. American Elements maintains solution production facilities in the United States, Northern Europe (Liverpool, UK), Southern Europe (Milan, Italy), Australia and China to allow for lower freight costs and quicker delivery to our customers .American Elements metal and rare earth compound solutions have numerous applications, but are commonly used in petrochemical cracking and automotive catalysts, water treatment, plating, textiles, research and in optic, laser, crystal and glass applications. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered. We also produce Potassium Nitrate Powder. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Potassium (K) atomic and molecular weight, atomic number and elemental symbol Elemental PotassiumPotassium (atomic symbol: K, atomic number: 19) is a Block S, Group 1, Period 4 element with an atomic weight of 39.0983. The number of electrons in each of Potassium's shells is [2, 8, 8, 1] and its electron configuration is [Ar] 4s1. The potassium atom has a radius of 227.2 pm and a Van der Waals radius of 275 pm. Potassium was discovered and first isolated by Sir Humphrey Davy in 1807. Potassium is the seventh most abundant element on earth. It is one of the most reactive and electropositive of all metals and rapidly oxidizes. Potassium Bohr ModelAs with other alkali metals, potassium decomposes in water with the evolution of hydrogen; because of its reacts violently with water, it only occurs in nature in ionic salts. In its elemental form, potassium has a silvery gray metallic appearance, but its compounds (such as potassium hydroxide) are more frequently used in industrial and chemical applications. The origin of the element's name comes from the English word 'potash,' meaning pot ashes, and the Arabic word 'qali,' which means alkali. The symbol K originates from the Latin word 'kalium'.
