Method and apparatus for producing AlN whiskers, AlN whisker bodies, AlN whiskers, resin molded body, and method for producing resin molded body
A method and apparatus for producing AlN whiskers includes reduced incorporation of metal particles, an AlN whisker body, AlN whiskers, a resin molded body, and a method for producing the resin molded body. The method for producing AlN whiskers includes heating an Al-containing material in a material accommodation unit to thereby generate Al gas; and introducing the Al gas into a reaction chamber through a communication portion while introducing nitrogen gas into the reaction chamber through a gas inlet port, to thereby grow AlN whiskers on the surface of an Al 2 O 3 substrate placed in the reaction chamber.
1. A method for producing AlN whiskers, the method comprising:
heating an Al-containing material in a first chamber to thereby generate Al gas;
introducing the Al gas into a second chamber through a first inlet port while introducing nitrogen gas into the second chamber through a second inlet port; and
growing AlN whiskers on the surface of an insulating substrate placed in the second chamber.
2. A method for producing AlN whiskers according to claim 1 , wherein
the insulating substrate is any of an Al 2 O 3 substrate, an AlN polycrystalline substrate, Al 2 O 3 particles, and AlN particles.
3. A method for producing AlN whiskers according to claim 1 ,
wherein the atmosphere temperature in the second chamber is adjusted to 1,500° C. to 1,800° C. during growth of AlN whiskers.
4. A method for producing AlN whiskers, the method comprising:
heating an Al-containing material in a first chamber to thereby generate Al gas;
introducing the Al gas into a second chamber through a first inlet port while introducing nitrogen gas into the second chamber through a second inlet port;
growing a fibrous AlN single crystal on the surface of an insulating substrate placed in the second chamber;
forming an oxygen atom-containing layer on the surface of the AlN single crystal; and
forming a hydrocarbon group on the surface of the oxygen atom-containing layer.
5. A method for producing AlN whiskers according to claim 4 , wherein,
in formation of the hydrocarbon group, the method comprises
mixing the AlN single crystal comprising the oxygen atom-containing layer with stearic acid and cyclohexane, and
refluxing the resultant mixture.
