slag

[slag]
(metallurgy)
A nonmetallic product resulting from the interaction of flux and impurities in the smelting and refining of metals. Also known as bloom.

slag

A grayish aggregate left as a residue of blast furnaces; used as surfacing on built-up roofing and in manufactured products such as slag cement and slag wool. Also see blast-furnace slag.

slag

1. the fused material formed during the smelting or refining of metals by combining the flux with gangue, impurities in the metal, etc. It usually consists of a mixture of silicates with calcium, phosphorus, sulphur, etc.
2. a mass of rough fragments of pyroclastic rock and cinders derived from a volcanic eruption; scoria
