What would happen if pressable ceramic is heated past melting range?

  1. Apr 3, 2013 #1
    I'm currently looking into some dental material mechanics.

    Material: Pressable ceramic powder
    Melting range: 900-1000°C

    If I were to heat it up to approx 1200°C, what would happen to it? Would it still be just molten form of the material?

    Some single phase materials melt congruently (i.e., the liquid composition is the same as the solid), others exhibit various other modes of melting. Consult a phase diagram of the material you are working with.
