Transformation of BN and B powders and 25wt.% In in a high-flux optical furnace in flow of nitrogen was considered. Powders were collected at different distances from a reaction zone. In nanopowder with a thin oxidised layer was formed during heating BN and In at 1000 degrees C. Heating at 1500 degrees C s results in platelike and equiaxed BN particles, compose B inside and H3BO3 layer, nano-petal particles, compose InN and number of fullerene-like particles with complicated core shell' structure. The last was formed as a result of segregation of transparent shell of B components around crystalline fullerene-like InN. These structures arise from a bubbles evolution of B and In components in conformity with gaseous model for nanotubes and fullerenes formation and growth'. InN prevents the formation of new modifications of BN and shifting stretching band of BN according to FTIR. BN disclosed itself as an excellent getter for InN.
