SODIUM TETRABORATE ANHYDROUS (C005B-015217)

Application

Borax Anhydrous can be used as a boron source to synthesize phase pure ZrB₂ powder via a novel green silicothermic reduction method using ZrO₂ and Si as raw materials. It is also used to prepare sodium borohydride, nano-sized titanium diboride, and alkali-activated borosilicate inorganic polymers.
