Zinc melts at 420 °C (787 °F), [21] but importantly boils at 907 °C (1665 °F), a temperature below the melting point of silver. Consequently, at the temperatures needed to reduce zinc oxide to the metal, the metal is already gaseous. [23] [24] Arsenic sublimes at 615 °C (1137 °F), passing directly from the solid state to the gaseous state ...
