Thermal stability of rare earth densified ?-sialon ceramics
(1997)Typical ?-sialon and mixed ?-ß sialon starting compositions were densified by either hot pressing or pressureless sintering using the oxides of Yb, Dy, Sm and Nd. The resulting materials were heat-treated at 1450°C for up ... -
An ultrasonic motor using a metal-ceramic composite actuator generating torsional displacement
(Japan J Applied Physics, 1998)An ultrasonic motor composed of three components; a stator, a rotor and a ball bearing is proposed. The stator is made of an active piezoelectric ring, poled in the thickness direction and bonded with two windmill-like ... -
Use of perlite in wall tile production
(Amer Ceramic Soc, 1999)Raw perlite was added to monoporous tile bodies in different proportions. Their mechanical, physical and thermal characteristics were compared to ones having no perlite. Adding perlite to wall tile bodies offers both weight ... -
The use of waste ceramic tile in cement production
(Pergamon-Elsevier Science LTD, 2000)In ceramic tile production, because of various reasons, unsold fired products come out. These are waste tiles and only a little part of them are used. Remainings create environmental problems. If these waste tiles are used ... -
?ݧ Sialon Transformation in Calcium-containing ? -SiAlON Ceramics
(1999)Recent studies on rare earth densified ?-sialon ceramics have shown that the resulting ?-sialon product, present either as a single phase or in conjunction with ß-sialon, is unstable when heat treated at lower (1350-1600°C) ...
