HRTEM observations require ultra-thinned specimens and, due to the very small thick- ness (1 to 30 nm), an elastic stress relaxation may occur near the free surfaces of strained heterostruc- tures. These relaxation phenomena can modify the structural features of the thinned specimens with respect to the bulk materials…

ZrO2-MgO-Al2O3 powder composites were prepared by calcining gelled mixtures of Mg(OH)2, Zr-n-butoxide and Al-sec-butoxide (or Al2O3) at 1000°C for 2h. The calcined powder was cold isostatic pressed at 200MPa and sintered at 1500 to 1650°C for 1h. Fine and homogeneous tetragonal-ZrO2 grains were dispersed in the sinter…

Mullite/zirconia composite materials were characterized in terms of electrical conductivities, structure and microstructure. It was found that the conductivity assumes a minimum at about 10mass% ZrO2. The highest conductivity was observed in the range of 60-100mass% ZrO2. XRD studies have revealed that the tetragonal…

Gaseous oxygen impacts may occur in high-pressure oxygen systems whenever oxygen equipment is pressurized too fast. This is one of the main causes of fires in such systems. Therefore, equipment for high-pressure oxygen that contains nonmetallic sealing materials should be tested for burn-out safety. This is required b…
