Abstract
The compositional and morphological analyses have been carried out by employing XRD, EPMA, and SEM for the black-colored precipitate which is formed on the surface of heating appliances by heating tap water. XRD analysis has showed that the precipitate was mainly composed of calcium carbonate with a crystal structure of calcite. Also, small amounts of precipitate by SEM showed that the microscopic shape of the precipitate was usually angular spherical.
