Synthesis of Zeolite-A Using Silica from Rice Husk Ash

Rice Husk Ash-Derived Silica Nanofluids: Synthesis and Stability Study

Nanofluids, colloidal suspensions consisting of base fluids and nanoparticles, are a new generation of engineering working fluids. Nanofluids have shown great potential in heat/mass transfer applications. However, their practical applications are limited by the high production cost and low stability. In this study, a low-cost agricultural waste, rice husk ash (RHA), was used as a silicon source...

Ultrasonic and conventional synthesis of NaA zeolite from rice husk ash

Synthesis and Characterization of Porcelain Body Developed from Rice Husk Ash (TECHNICAL NOTE)

For a developing country like Bangladesh, waste management is an important issue. Since it is a small over-populated country , strict government regulations regarding landfills is essential. Expansion of ceramic industries is considered to be one of the potential sectors for the economic growth of Bangladesh. However, raw material cost per unit production is the prime concern for industrialists...

Synthesis of Si/MgO/Mg2SiO4 Composite from Rice Husk-Originated Nano-Silica

Silica exists in Rice husk, an agriculture waste, as a naturally occurring phase. In first step, acidic pre-treatment and calcination of the rice husk were performed to obtain nano-silica, in which various sizes of the nano-silica, totally with sizes under 80 nm, were achieved. Second, to reduce nano-silica to elemental Si and subsequently formation of the composite, Mg used as the reducing age...

The 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 ...
