Abstract
The corrosion-resistance of transparent ceramic MgAl2O4 was studied under the conditions of different concentrations and temperatures.The results indicated that transparent ceramic MgAl2O4 had relatively good corrosion resistance in hydrochloric acid,phosphoric acid and sodium hydroxide with different concentrations at normal temperature and 75 ℃.The corrosion resistance of transparent ceramic MgAl2O4 in concentrated phosphoric acid was bad at temperatures higher than 300 ℃ but good in fused sodium hydroxide.
