There is a fundamental difference in reaction zone morphology between Ti/SiC where both stable carbide and silicide are formed, and Pt/SiC where only a stable silicide is formed. The product phase interfaces in the PVSiC case are often smoothly curved (fig. 3, ref. 2)
X-FAB continues to drive the adoption of silicon-carbide (SiC) technology forward by offering SiC foundry services at the scale of silicon. As the first pure-play foundry to offer internal SiC epitaxy and with a proven ability to run silicon and SiC on the same manufacturing line, our customers have access to high-quality and cost-effective foundry solutions.
the exothermic polymerization reaction of acrylic resin. All specimens were then ground with 600-grit silicon carbide (SiC) paper, and cleaned in an ultrasonic water bath for 10 min. The cleaned samples were then divided into four groups. The specimens
Lithium contg. silicon carbonitride ceramics (SiCN:Li) were synthesized via precursor-to-ceramic-transformation of Li-contg. (poly)silazanes. The precursors were obtained by lithiation of the model compd. 2,4,6-trimethyl-2,4,6-trivinylcyclotrisilazane and of a com
A ceramic is any of the various hard, brittle, heat-resistant and corrosion-resistant materials made by shaping and then firing a nonmetallic mineral, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick.The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, vitrified, and often completely amorphous (e.g., glasses).

polymerization reaction of the acrylic resin. All specimens were ground with 600-grit silicon carbide paper and airborne particle abraded with 50-μm grain size Al 2O 3 particles at 0.2 MPa pressure for 20 s at a distance of 10 mm. The specimens were then
The microstructures of zirconia reinforced with silicon carbide fibres prepared by the sol–gel process have been examined using a transmission electron microscope. The characteristic feature of highly oriented grains of monoclinic zirconia, with its unique b-axis as well as c-axis of the tetragonal structure nearly all parallel to the hot pressing plane, shows the formation of matrix texture
filler metals to ceramics, metallisation of the ceramic surface (Mo-Mn paste, hydride PVD coating) followed by a reaction thermal treatment are often used. Direct or active brazing has been developed to simplify the manufacturing of brazed ceramic joints: the filler metal contains
