Influence of sintering temperature

The highest luminescence product consists of spheroidal and relatively uniform particles with sizes around 0.6-1.0 µm. The variation of the precipitated precursor with temperature, the influence of sintering temperature on structure and luminescence, the mineralization role of boric acid and the chemical reactions that occur with generation of precipitated precursors and upon heating to give luminescent solid solution products are mentioned.

The aim of this research is to investigate the influence of the sintering temperature on the properties of the in-situ carbide (Nb,Ti)C in a copper matrix synthesized via mechanical alloying and powder metallurgy from elemental powders of Cu, Nb, Ti and graphite. The mixture of starting powders with compositions corresponding to Cu-15vol.% (Nb, Ti)C was mechanical alloyed using a planetary ball mill for 20 hours.

The Tb3+ rare-earth-ion-doped Ca2Al2SiO7 material has a tetragonal phase structure that was successfully synthesized using the solid-state reaction method under optimal conditions: sintering temperature: 1280 °C; time: 60 minutes; and the B2O3 flux agent content: 4% wt. The photoluminescence spectrum of Tb3+ doped Ca2Al2SiO7 phosphor consists of narrow lines with peaks at 545, 440, 462, 494, 590, and 622 nm that correspond to 4f electronic transitions of the Tb3+ ion. The peak at 545 nm has the highest luminescent intensity.

In this study we report the effect of sintering temperature on the low field magnetoresistance (LFMR) of La0,7Ca0,3MnO3 manganite synthesized through sol-gel technique. The La0,7Ca0,3MnO3 has been sintered at 600˚C, 700˚C, 800˚C, 900˚C and 1200˚C. The crystallite as well as particle size also show strong dependence on the sintering temperature. While the ferromagnetic – paramagnetic (FM-PM) transition temperature remains almost constant, the metal – insulation transition temperature drop gradual and the low field magnetoresistance (LFMR) increase with a decrease in grain size.

Research results on 3D modeling of the diamond grain and its bearing layer when sintering diamond grinding wheels are provided in this paper. The influence of the main characteristics of the wheel materials and the wheel production process, namely the quantity of metallic phase within diamond grain, coefficient of thermal expansion of the metallic phase, the modulus of elasticity of bond material and sintering temperature, on the internal stresses arising in grains is investigated. The results indicate that the stresses in the grains are higher in the areas around the metallic phase.

The influence of fabricating conditions such as gelization, sintering temperature on crystallinity was studied. The result showed that Bi0.5Na0.5TiO3 was in single phase when compenstation amount of Na in gelization is 40 mol%; sintering temperature higher than 800 oC and sintering time is 2 h. The bandgap of Bi0.5Na0.5TiO3 which estimated from absorption spectroscopy is in the range of 3.01 - 3.18 eV.
