why does calcium fluoride have a higher melting point …

6/9/2007· Calcium fluoride (CaF2) is an insoluble ionic compound of calcium and fluorine. Strong charge-charge electric atraction exists between every pair of closely loed Ca and F ions, hence the melting point must be very high. On the other hand, F2 is a non-polar

Iridium powder manufacturers-Metal-oxide-materials

Use :The high melting point, hardness and corrosion resistance of iridium and its alloys determine most of its appliions. Iridium and especially iridium–platinum alloys or osmium–iridium alloys have a low wear and are used, for example, for multi-pored spinnerets, through which a plastic polymer melt is extruded to form fibers, such as rayon.[57]
