چکیده
The impact of sintering duration on willemite-based glass-ceramics (WGC) derived from the ZnO-B2O3-SiO2 host system through a conventional melt-quenching method by incorporating rice husk ash (RHA) as silica (SiO2) source was comprehensively studied means physical, structural, and optical properties. increment elevated diffusivity rate resulting in gradual bulk density linear shrinkage over time. XRD patterns affirmed ?-Zn2SiO4 phase formed after at 700?C for 2 h, followed crystallization higher holding FESEM observation revealed that Zn2SiO4 embedded glassy solid grew equiaxed shape crystals time increased. Absorption spectra increasing trend absorption bands with an increase due to intensification thus escalating green emission. Thus, this WGC will be applied optically phosphor materials.

Extensive application of silica nanoparticles (SNPs) in various industrial products has led to the development of silica extraction methodologies out of various waste products. Rice husk is an agricultural waste with a high content of amorphous silica. However, the presence of metal ion impurities and unburned carbon in the rice husk content may present an adverse effect on product color and pu...
متن کاملThe Synthesis and Characterization of Cobalt-Rice Husk Silica Nanoparticles
Spherical and needle-like cobalt nanoparticles incorporated on rice husk silica was synthesized by a simple, rapid and eco-friendly sol-gel route at room temperature. This was achieved by direct mixing of 20 wt.% Co with sodium silicate from rice husk under ambient conditions to form RH-20Co. The cobalt was found to be isomorphously substituted in the silica matrix. A good dispersion of cobalt ...

متن کاملSintering Behavior and Properties of Iron-Rich Glass-Ceramics
Iron-rich glass-ceramics were obtained by the sintering of two glass powders, labeled G1 and G2, at heating rates of 5° and 20°C/min followed by an isothermal step in the 850°–1050°C temperature interval. The sintering process was evaluated by the linear shrinkage; the closed porosity was estimated by density measurements; the structure and the morphology of the glass ceramics were observed by ...
