Editing Bort (section)

== Use and application ==
Bort is commonly used as an [[abrasive]]. Smaller flakes and particles are used as an additive for scouring or polishing pastes and agents. Larger particles can be added to cutting, drilling and grinding tools to improve their lifespan and substantially increase their efficiency.<ref name="usage_1" />

Bort particles varying from one to two [[nanometer]]s<ref name="sn-1" /> are added to [[lubricant]]s such as [[Mineral oil|paraffin oil]]. These particles will embed themselves into minute irregularities and imperfections of moving-part surfaces. Particles that remain [[Suspension (chemistry)|suspended]] in the lubricant oil act as both a polishing agent, further smoothening the surfaces, and as [[ball bearing]]s between the surfaces. Such [[nanotechnology]] applications with paraffin oil containing approximately 1% of these nano-size bort particles may decrease the [[friction]] up to half of that without the nano-particles.<ref name="aiche.org-1" /><ref name="nrc.nl-1" />
