Abstract
A process to produce magnesium diboride objects from boron objects with a similar form is presented. Boron objects are reacted with magnesium vapor at a predetermined time and temperature to form magnesium diboride objects having a morphology similar to the boron object's original morphology.
Claims18
A method for producing a magnesium diboride object comprising the step of reacting a boron object with magnesium vapor at a predetermined time and temperature to form the magnesium diboride object.
A method for producing a magnesium diboride object comprising the steps of:
- feeding the boron object into a reaction vessel having magnesium vapor within the reaction vessel;
- reacting the boron object with the magnesium vapor for a predetermined time at a predetermined temperature;
- removing the formed magnesium diboride object from the reaction vessel;
- and
- cooling the magnesium diboride object at a predetermined rate.
A method for producing a magnesium diboride object comprising the steps of:
- putting a boron object and magnesium into an inert tube;
- heating the inert tube to a predetermined temperature for a predetermined time to form the magnesium diboride object;
- cooling the magnesium diboride object at a predetermined rate;
- and
- removing the formed magnesium diboride object from the inert tube.
