Silica nanoparticles have been prepared by planetary ball mill method at room temperature at different milling hours using Malpe beach sand, Karnataka, India. The result occurred in 150 hours milling time at 250 RPM to produce silica nanoparticle less than 100 nm in size. The synthesized Nanoparticles were
The negative effects of sand mining on local wildlife are clearly visible in the case of gharials, the fish-eating crocodiles, in India. Sandbanks are essential for the critically endangered gharials to build nests and bask in the sun. Unfortunately, …
Table 5 shows that there is a gradual increase in the average effects starting from level 1 to level 3 for factors temperature, time and duration of mechanical milling for silica sand. These observations indicate that the percentage yield of SiC (in terms of the weight of product obtained) formation would increase when temperature, time, and duration of mechanical milling for silica sand ...
This paper presents the investigation carried out to study the formation of silicon nitride and silicon carbide compound from the reaction of silica sand powders with carbon in nitrogen with 5% hydrogen atmosphere at temperatures between 1350 °C to 1550 °C. The effect of mechanical milled silica sand and different temperature during carbothermal reduction process was determined.
