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.
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.
Results indicate the cement’s electrical conductivity is on par with that of manganese at room temperature.
Moreover, like other metals, the cement’s conductivity increases as its temperature decreases.
The researchers say that forming the cement into thin membranes would make it nearly transparent, making it an ideal substitute material for rare metals such as indium.
In addition to being cheaper than rare metals, the cement would make an environmentally-friendly alternative because its ingredients are more readily available.

Also, imagine it being your house floor. When your security alarm is tripped, it automatically electrifies the floor until deactivated. Levels set to 'stun' could be great burglar deterrent (until they start wearing rubber soled shoes)
