These studies include doping metal ions into the photocatalyst lattice and coupling semiconductors (Behnajady et al. 2007). The presence of metal ion dopants in the ZnO matrix significantly influences the charge carrier recombination rates and interfacial electron-transfer rates.
Oct 17, 2017 · LHT 01/17 D | High-Temperature Furnaces up to 1650 °C Suitable for Sintering Translucent Zirconia . This high-temperature furnace is perfectly suited for sintering of translucent zirconia units. The special molybdenum discilicide heating elements offer best possible protection against chemical interaction between
During investment casting, the molten metal is poured into the ceramic mold to cast the components using gravity, pressure, vacuum, and centrifugal methods. The applied furnace and casting technique finally depends on the alloy type, pouring temperature, throughputs, and applications.
Thus, the specific surfaces of the S, M, and L specimens were 2.9, 1.5, and 1.4 mm2/mm3, respectively. Thermal debinding, sintering, and nitriding were performed continuously in a vacuum and gas-atmosphere furnace. Sintering was performed at 1,150°C, 1,200°C, and 1,250°C for 2 h.
The wax-like texture of Ceramill Sintron allows the material to be dry milled effortlessly. During the subsequent sintering process under shielding gas atmosphere the frameworks achieve their final material properties – a CoCr unit with very homogeneous material structure. Any conventional CoCr framework porcelain can then be used for veneering.
Within the limitations of this study, the millable Co-Cr alloy exhibited a shear bond strength equivalent to that of the castable alloy. The millable Co-Cr alloy is an alternative to the castable alloy for metal-ceramic restorations. CAD/CAM manufacturing can be efficiently used in Co-Cr restorations.
The presented paper studies the eﬀect of the casting technology on the corrosion resistance of Co-Cr-Mo alloy. The investigations were conducted on a commercial alloy with the brand name ARGELOY N.P SPECIAL (Co-Cr-Mo) produced by Argen as well as the same alloy melted and cast by the lost wax casting method performed by a dental technician.
It should be mentioned that the galvanic corrosion behavior of dental alloys is expected to fluctuate over time due to various factors, including changes in the pH and composition of saliva, disruption of the alloy's passive film due to chewing, and aging of the restoration.
Dec 15, 2009 · FIG. 3B illustrates the deposition of a second material on the first material of FIG. 3A using laser based metal deposition (LBMD); FIG. 3C is a micrograph at 5× magnification that shows three layers of Co—Cr alloy deposited by the LBMD process on a bulk material of wrought Co—Cr;

The term "wrought iron" is often misused today; it is commonly used to describe designs similar to historical wrought iron pieces—regardless of the metal used. Mild steel that has been machine-bent into shape in a cold state or cast steel and iron pieces that have been painted black are both regularly mislabelled as wrought iron work.
