Can We Break the Rule?

01/31/2007 11:06 AM

I wonder if a metallic character could result from the combination of two non-metallic combination.

"Metallic character" can mean lots of things. For example, certain polymer nanostructures are electrically conductive (like metals) in one direction, but are insulators (like dielectrics) in a perpendicular direction. (See the abstract "Fabrication of high-density, large-area conducting-polymer nanostructures" here). Is something like this what you had in mind?

Thank you for the reply and i must confess that i even learnt from your reply,i am actually an undergraduate of metallurgical and materials engineering at the University of Lagos Nigeria and i found this forum exceedindly helpful to me especially when all we do here is abstract engineering but i have been constantly driven by my desire to learn and be useful.What i mean by metallic character in that context is that,for example,we understand that an alloy is a solid solution(combination) of two or more metals(but in some cases it could be a combination of a metal and a non metal).Whichever way,a metal must be present in the constituent(the important thing to note at the end of the day is that the alloy exhibits a metallic character).What i wanted to know is that if the constituents of the alloy were all non metals(perhaps in some special cases),could there be a possibility of the alloy exhibiting a metallic character?

Given the correct temperatures and pressures hydrogen behaves like a metal. Please qualify the question.

An excellent example. A thick inner jacket of metallic hydrogen probably explains the existence of Jupiter's enormous magnetic field (if Jupiter's magnetosphere were visible, it would be larger than a full moon as seen from Earth).
