In chemistry, a compound (also called a compound body, as opposed to the simple body) is a pure chemical substance (molecular compound, ionic assembly, intermetallic compound, complex) composed of atoms of at least two different chemical elements. The atoms forming the assemblies of chemical compounds are linked together by chemical bonds, which can be of different natures. Micron powder is consisting of tiny particles less than 100 µm. These are very small finely crushed particles in which electrons have very strong bonding. There are two types of compounds namely organic and inorganic compounds. Organic compounds are those compounds that are based on carbon skeleton (some exceptions are CO, CO2, CN) and all other compounds which are not included in the organic compound are inorganic compounds. The powder of compounds that has a size ranging from 10 µm to 100 µm is called compound micron powder.
