In situ Sintering of Agglomerated 3% Yttria-stablized Zirconia

Effect of impurities on sintering and conductivity of yttria-stabilized zirconia

The effect of low concentrations of Fe203, AI203 and Bi203 on the sintering behaviour of (ZrO2)o.83 (YO1.s)o.17, made by alkoxide synthesis, has been investigated. The best results are achieved with Bi203 as a sinter agent and a relative density of 95% is obtained at 1200 K. The effects of these impurities on the electrical conductivity of the bulk and the grain boundaries has been investigated...

An extended Kalman filter for in situ sensing of yttria-stabilized zirconia in chemical vapor deposition

Chemical vapor deposition (CVD) is an important step in integrated circuit fabrication and is a dynamic process that is complex and subject to unmeasured disturbances. Currently in semiconductor industry the main form of advanced process control for CVD is run-to-run (R2R) control. R2R control is a form of discrete process control in which the processing recipe is modified ex situ based on post...
