Borazon

/ˈbɔːrəzɑːn/ noun

Definition

A synthetic abrasive material made from boron nitride, nearly as hard as diamond and used for grinding and polishing.

Etymology

A brand name (trademark) coined from 'boron' plus 'azon' (perhaps meaning 'horizon' or created as a coined term). Introduced by General Electric in the 1950s.

Kelly Says

Borazon is the second-hardest material known to humans after diamond, but it's actually better for some industrial applications because it won't react with iron or steel!
