Scientists who are working on newer and better materials out of which to make things are concentrating their attention on ceramics. Ceramics do not break or wear as easily as other materials, including metals. High temperatures don't cause them to weaken. Some ceramics have even shown the promise of bringing about another revolution in electronics. Ceramics have one major problem, though. They are difficult to form into usable parts. Sometimes they are also too brittle to work well as machine parts.
