The melting point of the inorganic perovskite compound CsPbBr3 is approximately 567 °C.
This temperature marks the point at which CsPbBr3 transitions from a solid to a liquid state. Interestingly, when it reaches this temperature, its sublimation process also begins. Sublimation is a direct phase change from a solid to a gas, meaning that at its melting point, CsPbBr3 can start to both melt and vaporize simultaneously. This characteristic is vital for understanding its behavior and stability in various applications, especially those involving elevated temperatures.
