New cement conducts electricity like metal
‘A team of researchers led by professor Hideo Hono of the Tokyo Institute of Technology has developed a new type of alumina cement that conducts electricity like metal by altering the crystal structure at the nano level.
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.’
