High-flux optical furnace presents a one of cleanest energy sources
available for the Nanotechnology. Concentrated light heating of an optical
furnace has number of advantages such as high heating and cooling rates,
versatility and ability to adjust temperature profile along each axis, maximum
operating temperatures and environmental adaptability. Moreover, this
technique is appropriate for both conducting and non-conducting materials.
Transformation of boron nitride and boron powders and mixture of 25 wt. %
in Al, Cu, Fe, Ni in flow of nitrogen was considered. The effect of temperature
distribution and temperature gradients within an experimental camera on
architecture, phase composition and other properties of obtained powdered
materials was demonstrated. The presence of catalyst promotes formation
of nanostructures. Formation of new architecture of nanostructures can be
explained in framework of “gaseous model” which was based on an evolution of
the bubble during heating in an optical furnace. Burst of these bubbles results
in graphene-like structures formation. The stepwise transformation of bubbles
of appropriate chemical composition leads to nanotubes formation because of
their pulling by heated gases upwards. Fullerene-like particles can also have
complicated “fish-eye” (“core shell”) structure in the result of segregation of
transparent BN shell with H3BO3 layer on the surface around crystalline InN.
Nano powder was prepared in an optical furnace under concentrated light
heating has complicated gradient or layered structure. According Raman, AES
and FTIR study the surface of all powders is composed of BN. XRD disclosed
pure amorphous boron inside particle. Gradient transformation of pure boron
to BN in the framework of one particle as well as layered nanostructure was
observed by TEM study.
