| 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. |
