Sugozu (2009) produced the brake pad specimens using ulexite
, colemanite, boric acid and borax pentahydrate which are boron derivatives, and then examined the properties of the produced brake pads including the friction, wear, and resistance.
Also in a study used Taguchi method , the optimization of the dissolution of ulexite
in SO2-saturated water has been investigated.

Three other commercially available B sources viz., borax, ulexite
and colemanite were also co-granulated with MAP.

in borax pentahydrate solutions.
The crushed ores are colemanite (Ca2B6O .5H O), ulexite
(Na O.2CaO.5B2O3.16H2O), datolite (2CaO.B2O3.2SiO2.H2O), hydroboracite (CaO.MgO.3B2O3.6H2O) and ascharite (2MgO.B2O3.H2O).
I once saw a 70-year-old lady encountering a fine acicular ulexite
specimen for the first time.
Within commercial products and the most important minerals that contain boron are the borax pentahydrate, sodium perborate, boric acid, colemanite and ulexite
. Different applications for these compounds exist, between which can be mentioned: fiber glass, enamels, fire delayers, fertilizers and agricultural herbicides (IPCS, 1998).
More than 230 different types of boron minerals are known in nature, but the number having commercial importance is limited to the following: tincal, colemanite, kernite, ulexite
, pandermite, boracite, szaibelyite and hydroboracite.
