%X Laboratory expxure of zinc was carried out under the condition of 0.9 x 902 and 90% relative humidity in order to investigate the characteristics of ded surface and its role in initial stage. Scanning electmn microscope (SIN/EDAX), IR microscope were used for the characterisation of ded surfaces. It was found that wer 10 h exposure resulted in a rather uniformly d l ncduls like mrphology with size about I-, which was not kept until local cornion sprouted wer a week mure. The cornion product on locally coded area with porous appearance, was mnposed of needle-shaped crystals. Based on the IR and EDAX, it was infered that the product was Z&Q(OH)6 .5H20. The mechanism of atnmpheric cornion for zinc under the condition is discussed.
