Identifying Ceramic Corrosion Corroded Surface of Sintered YBa 2 Cu 3 O 7. Under extreme conditions it is necessary to understand the mechanisms which cause the break down of ceramics. Here Secondary Ion Mass Spectrometry (SIMS) is used to analyze the various types of corrosion of YBa 2 Cu 3 O 7.

Corrosion of Alumina Ceramics Often used as a reactor material in Supercritical Water Oxidation at temperatures of 500˚C and pressures up to 30MPa. Impurities in the Alumina Ceramic can leach into the solution and create acids.

Importance of Application Method Ti and B 4 C applied by RPS Ti and B 4 C applied by LPPS Y 2 O 3 protected Zirconium Oxide

Conclusion Leaching is an important factor Impurities and porosity lead to leaching Method of application must be thoroughly researched for any application of ceramics
