Abstract
The problem to be solved is to provide a boron nitride particle stably and efficiently with a high organic modification ratio.To solve the problem, the continuous production method according to the present invention comprises contacting step for continuously supplying a boron nitride with pretreatment and an organic modifier to continuously contact them with an aqueous material in a subcritical state in a presence of an acid or a base. The pretreatment comprises any one or more kinds selected from adding an acid to the boron nitride, adding a base to the boron nitride, adding an oxidant to the boron nitride, adding a reductant to the boron nitride, and conducting a hydrothermal treatment or a solvothermal treatment to the boron nitride.
