Third-person singular simple present indicative form of fuse.
It fuses considerably below and is perceptibly volatile at a red heat.
It is a colourless crystalline solid which readily fuses to a yellow liquid.
It fuses at 1078°.
It fuses at 415° C. and under ordinary atmospheric pressure boils at 1040° C. Its vapour density shows that it is monatomic. The molten metal on cooling deposits crystals belonging to the hexagonal system, and freezes into a compact crystalline solid, which may be brittle or ductile according to circumstances.
It is a dark yellow powder, which fuses at a high temperature, the liquid on cooling depositing shining tabular crystals; at a white heat it loses oxygen and yields the monoxide.
