Claims23
A method for producing magnesium hydride, the method comprising a plasma treatment step of exposing a raw material mixture of (i) at least one magnesium-based raw material selected from the group consisting of magnesium, magnesium hydroxide, and magnesium oxide, and (ii) magnesium hydride to hydrogen plasma.
A method for producing tetrahydroborate, the method comprising:
- a magnesium hydride production step of exposing a raw material mixture of (i) at least one magnesium-based raw material selected from the group consisting of magnesium, magnesium hydroxide, and magnesium oxide, and (ii) magnesium hydride to hydrogen plasma;
- and
- a mechanochemical treatment step of subjecting an object to be treated containing borate and the magnesium hydride obtained by the magnesium hydride production step to a mechanochemical treatment.
A method for producing tetrahydroborate, the method comprising:
- a magnesium hydride production step of exposing a raw material mixture of (i) at least one magnesium-based raw material selected from the group consisting of magnesium, magnesium hydroxide, and magnesium oxide, and (ii) magnesium hydride to hydrogen plasma;
- and
- a treatment step of subjecting an object to be treated containing borate and the magnesium hydride obtained by the magnesium hydride production step to a thermal treatment under conditions including a temperature of 350° C. or higher and an absolute pressure of 0.2 MPa or more.
A method for producing tetrahydroborate, the method comprising:
- a magnesium hydride production step of exposing a raw material mixture of (i) at least one magnesium-based raw material selected from the group consisting of magnesium, magnesium hydroxide, and magnesium oxide, and (ii) magnesium hydride to hydrogen plasma;
- and
- a plasma treatment step of exposing a mixture of borate and the magnesium hydride obtained by the magnesium hydride production step to hydrogen plasma or inert gas plasma.
A method for producing tetrahydroborate, the method comprising:
- a magnesium hydride production step of exposing a raw material mixture of (i) at least one magnesium-based raw material selected from the group consisting of magnesium, magnesium hydroxide, and magnesium oxide, and (ii) magnesium hydride to hydrogen plasma;
- and
- a thermal treatment step of heating a mixture of borate and the magnesium hydride obtained by the magnesium hydride production step to 350° C. or higher in a gas atmosphere containing hydrogen (H) as a constituent element.
