It is necessary to control the temperature in the torch in order to control nanopowder(NPs) synthesis process using induction thermal plasmas. The authors have studied NPs synthesis process using pulse-modulated induction thermal plasmas (PMITP). This report describes two-dimensional (2-D) observation result of TiO radiation intensity and estimation result for 2-D distribution of Ti excitation temperature during TiO₂ NPs synthesis using PMITP.
