Utilizing of Borax solid wastes in roof tile and brick bodies
(2006)Boron minerals are widely employed in various fields such as ceramic, glass, cement, metallurgy, etc. Although boron deposits of the world are limited, the production level of boron-based products is continuously increased. ... -
Roll pressing of sodium perborate monohydrate
(2006)Sodium perborare monohydrate (SPM) is produced by calcining 3 moles of water of sodium perborate tetrahydrate with fluidized bed dryer. In fluidized bed dryer, the powders of the sodium perborate monohydrate are sucked by ... -
Piezoelectric actuator designs
(Springer US, 2008)Piezoelectric actuators are getting immiscible parts of many important electromechanical and smart systems. Smart systems consist mainly of sensors, actuators, and signal processing units. Actuators are the responding units ... -
Development strategies for sialon ceramics
(2008)SiAlON ceramics have a wide range of applications due to their favorable mechanical and thermal properties. They are one of the main groups of materials being considered for high temperature load bearing applications and ... -
Optimization of ?-sialon microstructure by heat treatment
(2008)Nd-doped ?-SiAlON starting composition (Nd0.33Si 9.38Al2.62O1.62N14.38) was prepared by gas pressure sintering at 1825°C for 3 hrs. In order to explore the effect of post heat treatment on the developments of elongated ... -
Production and industrial adaptation of fast single firing wall tile opaque glass-ceramic glazes containing borax solid wastes
(2008)Zircon (zirconium silicate) is the main opacifier of glossy, opaque, white colored, frit-based wall tile glazes. However, zirconia containing frits employed in the preparation of these glazes increase the production cost ... -
Textured ?-SiAlON ceramics via templated grain growth
(2007)In this study, textured ?-SiAlON ceramic was produced by templated grain growth process. In order to enhance the alignment of the seeds, gated tape casting arrangement was utilized. Y-Ce codoped seeds were synthesized to ... -
