moltenstate
Moltenstate refers to the liquid phase of a substance produced by heating above its melting point. In the molten state, particles have enough kinetic energy to overcome solid-state bonds and flow past one another. For pure crystalline materials, melting occurs at a specific temperature; for impure substances and alloys, melting happens over a range between the solidus and liquidus temperatures. Some materials, such as certain glasses, soften gradually rather than melting abruptly because of their amorphous structure.
In the molten state, properties such as viscosity, surface tension, and reactivity are strongly temperature dependent.
Applications include metal casting and alloy production, welding and additive manufacturing, glassmaking, and polymer processing. Temperature
