Procedure

In Loedige mixer (M-20 type (total volume: 20 L) available from Loedige), 8.51 kg (105 mol) of zinc oxide powder (JIS grade 2, available from HakusuiTech Ltd.) was placed. An aqueous solution of 1.67 kg (10.5 mol) of phenylphosphonic acid powder (Nissan Chemical Industries, Ltd.) dissolved in 9.43 kg of water was added thereinto (solid concentration in total mixture: 52% by mass). The resulting mixture was mixed for 5 minutes. Then, the mixture was dried for 60 minutes with mixing by flowing steam at 150° C. in the jacket provided with the apparatus surface and further dried for 70 minutes under reduced pressure, yielding a white powder of zinc phenylphosphonate-containing zinc oxide.
