Temperature Dependent Ionization

Is the Wikipedia article on plasma not available in that part of the world?

Cheers to PWSlack... what is really strange is it takes more time to log in to CR4, type the question, preview the question, submit the question, and wait for someone to answer - than it does to type in "wiki plasma physics" in the google line and press return!!!!

Aside from plasmas made from super-heated materials, I can think of two other materials that lose their polar properties, but without being ionized -- and at much lower temperatures than plasmas. Magnets will lose their magnetism at the 'curie' temperature. Liquid crystals, like in a laptop computer display, will lose their polar crystalline properties at temperatures of around 60C to 110C.

Thermotropic liquid crystals do as temperature is changed, the other two types of liquid crystals will, but as a function of both temperature and concentration of molecules, and the inorganic to organic ratio for the metallic types. But as you point out, they are not ionized by heating.
