Procedure

In Loedige mixer (M-20 type (total volume: 20 L) available from Loedige), 5.67 kg (70 mol) of zinc oxide powder (JIS grade 2, available from HakusuiTech Ltd.) and 1.11 kg (7 mol) of phenylphosphonic acid powder (Nissan Chemical Industries, Ltd.) were placed. While mixing these powders, 0.72 kg of water was sprayed thereto over 1 minute (solid concentration in total mixture: 90% by mass), and further mixed for 5 minutes. Then, the mixture was dried for 90 minutes with mixing by flowing steam at 150° C. in the jacket provided with the apparatus surface, yielding a white powder of zinc phenylphosphonate-containing zinc oxide.
