Abstract

The influence of eight different chlorides (BaCl(2), CaCl(2), KCl, LiCl, MgCl(2), NaCl, PbCl(2), and ZnCl(2)) on the oxidation of metallic chromium powder was studied at four different temperatures (400 degrees C, 500 degrees C, 550 degrees C, and 600 degrees C) under dry conditions in synthetic air by using a DTA/TG-apparatus. BaCl(2), CaCl(2), and MgCl(2) did not react with chromium at any of the studied temperatures. ZnCl(2) evaporated already before the air was introduced. KCl, LiCl, NaCl, and PbCl(2) were all found to be reactive and to accelerate the oxidation of chromium. LiCl reacted only at 600 degrees C, whereas the other three chlorides mentioned above reacted from 500 degrees C upwards.
