AI Thread Summary
Heating pressable ceramic powder beyond its melting range of 900-1000°C to approximately 1200°C could result in a molten form of the material, but the specific behavior depends on the material's phase diagram. Some materials melt congruently, meaning the liquid composition matches the solid, while others may exhibit different melting behaviors. Understanding the phase diagram is crucial for predicting how the material will react at elevated temperatures. The properties of the resulting molten ceramic could vary significantly based on its composition and melting characteristics. Proper analysis of the phase diagram is essential for accurate predictions regarding the material's behavior when heated.

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.
