Yttrium Disilicate

AbstractThe relative intensities ratios for the determination of the relative amounts of alpha and beta phases in silicon nitride and the relative amounts of delta yttrium disilicate (Y2Si2O7) and nitrogen apatite [Y5(SiO4)3N] are reported. These constants were determined using an iterative method applicable when the pure phases are not easily prepared. In addition, a calibration curve was obtained for the quantitative measurement of free silicon in silicon nitride over the range 0 to 0.3% by weight of Si.

Poor Adhesion

Natural fiber composites require coupling agents between phases to prevent poor adhesion between lignocellulosic fiber and a polymer matrix, which leads to a material that is not fully biodegradable. This work proposes the use of starch gum as a coupling agent for cotton fibers. The gum formation and fiber coating were characterized based on the starch paste solubility, clarity level according to UV-visible spectroscopy, Fourier transform infrared spectroscopy, thermal gravimetric analysis, heated optical microscopy, and fiber weight coating. Water-starch solutions were heated at 70 ℃ for 5, 10, and 24 h with two concentrations (3 and 8 wt.%) to obtain six different systems of gelatinized starch and starched fibers. The fibers are coated during the process of gelatinization and then dried and vacuum filtered. The gelatinization occurs at 70 ℃ for bath samples heated for more than 5 h, which exhibits a more branched structure, higher thermal stability, and increased weight coating up to 140 wt.%. The recoating process promoted stronger fiber adhesion, which would make this reinforcement applicable in an industrial-scale process to produce fully biodegradable composites.
