Boric acid is formed of stacks of crystalline layers (see title image). Each such layer has a very tight bonding within itself, but the bonding between layers is relatively weak. This combination of strong and weak forces enables a relatively easy motion of the molecules, creating the low friction coefficient of the compound.
Ali Erdemir added that there are more economical and environmental benefits to the lubricant. The new lubricant is safer and more environmentally friendly than conventional lubricants that usually contain special chemicals. Also, boron is a plentiful resource, lowering production costs. Before the new lubricant can be mass produced and sold it still needs to undergo rigorous environmental and safety tests.
In 2004, the Israeli company ApNano Materials revealed the first ever solid lubricant based on nanotechnology. ApNano's material called NanoLub is made out of nano-spheres of inorganic compounds that were discovered at the Weizmann Institute of Science, Israel. One of the most important advantages of the NanoLub is the ability to stay effective even on non-polished surfaces. Usually, parts must be mechanically polished to achieve the smoothest possible surface in order to reduce friction. However, because of its nano ball bearing-like structure NanoLub can reduce friction very efficiently even for rough contacting surfaces.
