High Heat Treatment Temperature

Barium strontium titanate becomes famous among the microelectronic field due to its dielectric properties. Sol-gel method was used to prepare the Ba0.6Sr0.4TiO3and was deposited on SiO2substrate. The temperatures used in the heat treatment process were high temperature, 650°C. For high heat treatment temperature, the process was carried in 2 different times which were 15 min and 60min.The effect of the different temperature and time in the heat treatment process were analysed by using XRD. 650°C for 15 min and 60min, there are clearer peaks observed and the intensity of the 110 peak was sharper.

This research reports the successful synthesis and formation of nanocrystalline forsterite (Mg2SiO4) powder by sol-gel method as a second phase for using in soft tissue engineering nanocomposite scaffolds. As high-pure and nanostructured forsterite is expected to have better biocompatibility and bioactivity, heat-treatment process was done on the synthesized nanopowder to obtain high-pure nanocrystalline forsterite. However, during the synthesis of forsterite, it is very difficult to avoid the formation of MgSiO3 (enstatite) and MgO (periclase). Moreover, increasing of the treatment temperature resulted in the improvement of the purity of the sample and the formation of single-phase forsterite. The TEM micrograph of the synthesized forsterite after the final heat-treatment process indicated that the particles were nearly elliptical shaped morphology and the size was in the range of 10 to 20 nm. This research also demonstrated that the pure forsterite did not show any signs of toxicity after 48 h with fibroblast cells and the cytotoxic scale was measured as zero. In addition, the combined results of the microstructural and biological studies suggested that this material exhibit good potential and biocompatibility for soft tissue engineering applications.

Network carbide inheritance during heat treatment process of large shield machine bearing steel GCr15SiMn was investigated by heat treatment experiments and quantitative metallographic. Samples with the proeutectoid cementite network thickness in the range of 0.19~0.54 μm were obtained by changing austenitizing temperature and soaking time of pearlite transformation. The results show that the network in hot rolled bar can be improved when the pre-heat treatment temperature is 950 °C. When the network thickness is above 0.40 μm, the undissolved cementite networks present in microstructures after quenching and tempering. In a Chinese standard, the network grades are 1.5 and 3.0 degree when the networks thickness are 0.40 μm and 0.54 μm, respectively. The critical network thickness that can be eliminated by heat treatment is 0.29 μm.

High Heat Treatment Temperature

Using SiO2– Al2O3– B2O3– K2O – Na2O system glaze as base material, under different temperature, sintering states of glaze were test. The influence of heat treatment on glaze melting characteristics was study. The results show that high heat treatment temperature can debase softening point, raise flow point, extend melting temperature range, long heat treatment time.has little effect on glaze melting characteristics.

To clarify the utilization of flue gas desulphurization (FGD) gypsum as the retarder of cementbased materials,the effect of the properties of the slag cement with different tempemtuIe treatment of FGD gypsum was studied. The results reveal that in the case of adding the same amount, the setting time of cement shortened with the increasing of heat treatment temperature of FGD gypsum. The influence of different heat treatment processes on the strength of cements was not obvious and the strength development was good. The water consumption of normal consistency for cements changed slightly. Stability was qualified.

Patterned Surface

Micropatterns of phenylsilsesquioxane thick films have been prepared by electrophoretic sol-gel deposition using ITO-coated substrates with a hydrophobic-hydrophilic patterned surface. After the electrophoretic deposition, phenylsilsesquioxane thick films were formed only on hydrophilic areas on the pattern. These thick films obtained immediately after the electrophoretic deposition were opaque due to light scattering. However, phenylsilsesquioxane particles in the films were morphologically changed from aggregates of the spherical particles to continuous phase by a heat treatment process, and finally convex shaped phenylsilsesquioxane micropatterns were formed only on the hydrophilic areas.
