Exfoliation Corrosion and Pitting Corrosion and Their Role …

At temperatures between 50 and 100 C, pseudoboehmite grows on the amorphous oxide. At 40°C, however, bayerite crystallization occurs and with time will overcome the pseudoboehmite [ 82 ]. Upon exposure of an air-formed film to water, the air-formed film will break down and another film will form that is thicker and contains more water.

Cadmium sulfide | CdS - PubChem

Eight rats from each group were saced at 1 day, 1 wk, and 14 wk after dosing for determination of cadmium (Cd) and zinc (Zn) concentrations in the lung, liver, kidney, and blood. Results indie that at 1 day after dosing, all enzyme activities (except acid phosphatase) and cell counts in BALF from the quartz and ZnCdS groups were significantly higher than in the TiO2 and saline groups.
