Wear and flexural strength comparisons of alumina/feldspar resin infiltrated dental composites.
INTRODUCTION Incorporating a feldspar chemical bond between alumina filler particles is expected to increase the wear-resistant and flexural strength properties. AIMS AND OBJECTIVES An investigation was carried out to evaluate the influence of the feldspar chemical bonding between alumina filler particles on wear and flexural strength of experimental alumina/feldspar dental composites. It was...
متن کاملFlexural strength of the joint between glass-infiltrated alumina frames and the alumina-magnesia modifier.
PURPOSE The purpose of the present study was to evaluate the flexural strength of the joint between glass-infiltrated alumina frames and the experimental adjusting agent (MA modifier) that contains alumina and magnesia. METHODS A commercially available adjusting agent (Optimizer), a slurry of alumina powder (Alumina modifier), and a bulk specimen (joint-free alumina) were used as controls. Be...
متن کاملSequential deposition of copper/alumina composites
Ceramic-metal composites have drawn considerable interest due to their mechanical, thermal and wear-resistant capabilities. High temperature processing of these materials when they are employed in electronic circuitry is not desirable, since elevated temperatures can irreversibly affect physical properties of the produced components. Wet chemical methods have potential advantages because they d...

متن کاملIn-Situ Alumina/Aluminate Platelet Composites
Alumina composites containing in-situ-formed hexaluminate (LaAl,,018, LaMgAl,,O,,, SrAl12019, and Mg,NaAl,,O,) platelets can be pressureless-sintered to high density. The grain morphology of the aluminates can be controlled by composition. A peak toughness 50% higher than that of alumina is obtained at 30 vol% aluminates, with a modest reduction (10%) in hardness and Young’s modulus. Although c...
