Chemical Reactions between CaZrO3 and SiC in Ar Atmosphere

摘要

The Chemical reactions between CaZrO3-SiC at high temperature (1200℃－1600℃） in Ar atmosphere have been investigated.The results have indicated that at high temperatures,chemical reactions would occur between CaZrO3 and SiC;the reaction products would change with increas of temperature.In Ar atmosphere CaZrO3 and SiC will react when the temperature reaches 1300℃，At 1300℃－1400℃ ZrC is formed ;above 1400℃ ZrC is transformed to ZrO.
