Response surface profiles showed the effects of ultrasonication time (X1), ratio of two phases (X2) and stabilizer concentration (X3) on PS (Y1) and PDI (Y2) of ETO nanopowder. (A) The effect of second-order interaction of ultrasonication time and stabilizer concentration (X1X2) on the PS and PDI of ETO suspension. (B) The effect of second-order interaction of ultrasonication time and stabilizer concentration (X1X3) on the PS and PDI of ETO suspension. (C) The effect of second-order interaction of ultrasonication time and stabilizer concentration (X2X3) on the PS and PDI of ETO suspension.
