, Small amounts of this brittle, flaky metal have been found in pure form, but it is usually found in compounds such as kermestite. Some alloys of this element share with water the rare property of expanding as they freeze, making it useful for moldin  gs. It is also useful as a hardening additive, 
, Small amounts of this brittle, flaky metal have been found in pure form, but it is usually found in compounds such as kermestite. Some alloys of this element share with water the rare property of expanding as they freeze, making it useful for moldin  gs. It is also useful as a hardening additive, and combined with tin and lead makes antifriction alloys called Òbabbitt metalsÓ. FTP, name this element with atomic number 51, whose chemical symbol, derived from the word Òstibnite,Ó is Sb.
