WebJan 30, 2024 · As the temperature increases to the point where it crosses the line, the solid will turn to liquid. In other words, it melts. If you repeated this at a higher fixed pressure, the melting temperature would be higher because the line between the solid and liquid areas slopes slightly forward. WebThe reaction has a low ignition temperature of less than 200 °C and is frequently used in “volcano” demonstrations. [8] Applications [ edit] Because of its considerable stability, chromia is a commonly used pigment. It was originally called viridian. It is used in paints, inks, and glasses.
