New Cement is Transparent, Conducts Electricity
Japanese researchers have altered the crystal structure of alumina cement and turned it into a thin, transparent membrane that conducts electricity. It might even be a substitute for rare metals such as indium which is used in plasma and liquid crystal displays, with less environmental damage because the materials are widely available.
"Ordinary alumina cement made from a lime-alumina compound (C12A7) has a crystal structure consisting of asymmetric cages, making it a poor conductor of electricity. But by sealing the alumina cement compound along with titanium inside a glass tube and heating it to 1,100 degrees Celsius, the researchers were able to create a homogenized, symmetrical cage structure that conducts electricity like metal."
