I Need Space Minerals!!

I am currently in the process of writing a science fiction novel. To make sure it sounds genuine, I was wondering if anyone could help define what kinds of minerals and mineral properties would be likely within the following areas of space:

Pre-Nova Star systems

Post-Nova Nebulae

Deep Space Asteroid Drift (Zero-G)

Close orbit asteroid belts

Asteroid belts in heavily magnetic region (magnetars)

Gases in Stellar Nurseries

I'd also like to know how the following mineral properties are created (where in the universe these properties are likely to be found):

Electro conductivity/resistance

Electromagnetism

Thermal conductivity/resistance

Highly ductile/malleable metals

Super dense, high shear/tensile strength metals

High radioactive minerals

And also =)

What is the state of common minerals (phosphate, sulfur, bromide) when introduced to space's vacuum?

Any help would be great, Thanks!
