Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
62 words
A process for manufacturing a fine powder of a metal or a metal compound or ceramics by causing a reaction between a volatile metal compound and/or an evaporated metal and a reaction gas which are provided as a mixture in a gaseous state, characterised in that said reaction is carried out in a discharged state while heating said mixture by laser beam.
Claim 2
Dependent Claim
62 words
A process for manufacturing a fine powder of a metal or a metal compound or ceramics by causing a reaction between a volatile metal compound and/or an evaporated metal and a reaction gas which are provided as a mixture in a gaseous state, characterised in that said reaction is carried out in a discharged state while heating said mixture by laser beam.
Claim 3
Dependent Claim
22 words
The process as claimed in claim 1, wherein said volatile metal compound is a halide, hydride or organic compound of a metal.
Claim 4
Dependent Claim
32 words
The process as claimed in claim 1, wherein said reaction gas is an inert gas or nitrogen, an organic or inorganic gas containing nitrogen, or an organic or inorganic gas containing carbon.
Claim 5
Dependent Claim
27 words
The process as claimed in claim 1, wherein said mixture is kept in a discharged state by direct current discharge and/ or high-frequency discharge and/or microwave discharge.
Claim 6
Independent Claim
80 words
An apparatus for manufacturing a fine powder of a metal or ceramics compound, said apparatus comprising a reaction chamber into which a mixture of a gas of volatile metal compound and/or an evaporated metal and a reaction gas is introduced for reaction, means for putting said reaction chamber in a discharged state by direct current discharge. and/or high-frequency discharge and/or microwave discharge, and means for irradiating laser beams through said reaction chamber in a discharged state to heat said mixture.
Claim 7
Independent Claim
80 words
An apparatus for manufacturing a fine powder of a metal or ceramics compound, said apparatus comprising a reaction chamber into which a mixture of a gas of volatile metal compound and/or an evaporated metal and a reaction gas is introduced for reaction, means for putting said reaction chamber in a discharged state by direct current discharge. and/or high-frequency discharge and/or microwave discharge, and means for irradiating laser beams through said reaction chamber in a discharged state to heat said mixture.
