Strontium titanate is an oxide of strontium and titanium with the chemical formula SrTiO3. At room temperature, it is a centrosymmetric paraelectric material with a perovskite structure. At low temperatures it approaches a ferroelectric phase transition with a very large dielectric constant ~104 but remains paraelectric down to the lowest temperatures measured as a result of quantum fluctuations, making it a quantum paraelectric.

Cobalt Nitrate is the Inorganic compound with the formula Co(NO3)2.xH2O. It is cobalt(II) salt. The most common form is the hexahydrate Co(NO3)2·6H2O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents.
Copper is the oldest-known metal used by humankind to make tools and decorations, helping form the transition from the Stone Age to the Bronze Age. After millennia of using wood, stones, and animal bones, copper transformed the abilities of early peoples, pushing them to invent ore smelting, mining, and metalworking.
Cuprous Oxide- The inorganic compound with the formula Cu2O. It is one of the principal oxides of copper, the other being another one is cupric oxide (CuO).

Iodine is extremely important to the life of animals and plants. Iodide and iodate in seawater enter the metabolism of most marine organisms. In advanced mammals, iodine is concentrated in the thyroid gland in the form of iodinated amino acids, and the lack of iodine causes goiter. About 2/3 of the iodine and compounds are used to prepare preservatives, disinfectants, and drugs such as iodonium and iodoform CHI3. Sodium iodate is insufficient as a food additive to supplement iodine intake.
Iodine is a purple-black lustrous flaky crystal with an atomic number of 53. The isotope that exists in nature is 74 neutrons of iodine-127. Iodine has a high vapor pressure and sublimes under slight heat. The pure iodine vapor is dark blue. If it contains air, it is purple-red and has a pungent odor.
