  Although orientation of a metal surface may be retained at the melting point, the decomposition of CH₂OH on Zn surfaces is now found to be catalyzed by ZnO; hence the constant rise in activity from solid to liquid Zn found by Steacie and Elkin (abs. 3264), is not conclusive proof of the nonexistence of active centers.  Further evidence is that catalytic oxidation of NH₃ by Sn is due to the oxide; hence the rate increases upon fusion, but the activity of Ag falls abruptly at the melting point, and the nature of the reaction changes because the oxide is not formed.  Mechanisms are cited for the formation of ZnO, and experiments show Zn chips to be coated with oxide.
