20200002241 · 2020-01-02 ·

The present invention provides an explosive composition comprising from about 2 to about 25 w/w hydrogen peroxide, from greater than 0 and up to about 90% w/w of one or more of other oxidisers. The present invention also provides a method of 5 preparing an explosive composition and use of the explosive composition of the invention to break and move ground, such as in mining operations.

Metal hydride nanoparticles

A nanoparticle of a decomposition product of a transition metal aluminum hydride compound, a transition metal borohydride compound, or a transition metal gallium hydride compound. A process of: reacting a transition metal salt with an aluminum hydride compound, a borohydride compound, or a gallium hydride compound to produce one or more of the nanoparticles. The reaction occurs in solution while being sonicated at a temperature at which the metal hydride compound decomposes. A process of: reacting a nanoparticle with a compound containing at least two hydroxyl groups to form a coating having multi-dentate metal-alkoxides.
