Science Buddies: "Ask an Expert"

Good day!
I was studying and I got thinking.
Some biological masses like the body can act wholly as conductors of electricity. Though, such a mass(the body) contains insulators as well as conductors on it various levels; cellular and other wise, yet it still conducts electricity. With that, some thoughts popped up, thus; firstly, is it possible to get a conductive inorganic substance like a solid copper mass fitted with insulative impurities? Secondly, if yes, would it still conduct electricity?

The Ask an Expert forums are for K-12 student science projects. If you are working on your own projects outside of this scope, there are other general science forums online where you may be able to post your question.
