Abstract
A chemically doped boron coating is applied by chemical vapor deposition to a silicon carbide fiber and the coated fiber then is exposed to magnesium vapor to convert the doped boron to doped magnesium diboride and a resultant superconductor.
Claims11
A method for producing doped boron, the steps consisting of:
- introducing a boron:containing vapor into a reaction vessel;
- introducing a dopant vapor into the reaction vessel to provide a mixture of the dopant vapor and the boron-containing vapor;
- and, heating the mixture to produce doped boron.
-20. (canceled)
A method for producing doped boron, the steps consisting of:
- (a) introducing a boron-containing vapor into a reaction vessel by metering a flow of hydrogen and metering a flow of boron trichloride vapor through the reaction vessel;
- (b) introducing a dopant vapor into the reaction vessel by passing at least a portion of the flow of hydrogen through a bubbler containing liquid titanium tetrachloride;
- mixing the hydrogen/titanium tetrachloride mixture emerging from the bubbler with the flow of boron trichloride going to the reaction vessel to form a boron-containing vapor/dopant-containing vapor mixture;
- and passing the boron-containing vapor/dopant-containing vapor mixture through the reaction vessel;
- and,
- (c) heating the boron-containing vapor/dopant-containing vapor mixture in the reaction vessel to produce doped boron.
