Challenges and Future Prospective of Alternative Materials to Silica
The sand casting process is widely used in foundries to produce or cast metallic products. It produces automobiles, aircraft, ships, and industrial machine components [].The green sand mould contains 85–95% of silica sand, 7–10% binder, around 5% coal dust, and 2–5% water [2, 3].Silica is the major ingredient of sand mould for For no-bake tests of self-setting SSBS, the dog bone cores were made from the mixture of 3200 g silica Sand1, 3% (based on the sand weight) water glass LS1 or LS2, 0.36% ester hardener, and with or without 0.5% MS addition. In the Kitchen Aid Mixer, after 2-min mixing of silica sand with MS powder, the water glass was added for another 2-minMicrosilica in Sodium Silicate Bonded Sands SpringerLink

Additive manufacturing of strong silica sand structures
The utilized powder material is a commercial foundry silica sand (SiO 2), with a mean diameter of 150 μm and bulk density of 2.8 g/ml, which was obtained from ExOne Corporation, USA.The silica sand powder from ExOne Corporation has a D50, which is the mean particle diameter of 100 µm. When printing with the ExOne X1-Lab system, it is suggested the layer height be double of the D50, so that it can encompass the majority of particles when the roller is moving the powder from the feed reservoir to the build reservoir.Additive manufacturing of strong silica sand structures

Silica Prices, Price, Pricing, News, Monitor ChemAnalyst
Silica sand prices remained stable at USD 61/MT FOB Hamburg, Germany, for March and February 2023 due to low demand from the domestic market despite ample supply. Regional freight charges remained high, and inflation was a driving factor for this price trend. In January 2023, prices increased by 1.7% due to partial improvement in demand amidstFeatures of silica sand cone crusher: Feed particle size: ≤385 mm. Discharge particle size: 3-64 mm. For secondary crushing in silica sand processing, the output particle size is finer and more uniform. The commonly used models of silica sand hydraulic cone crushers are HPM400 and GYS400. 2.

Facile Preparation and Characterization of Silica
Silica nanoparticles (SNPs) consist of several applications which include lightweight aggregates, energy storage, and drug delivery. Nevertheless, the silica reagents used in SNP synthesis are both costly and hazardous. As a result, it is critical to look for other sources of silica. For this research, a simple sol–gel hydrothermal approach is used Silica sand was milled by high-energy milling in order to reduce the size of silica sand to form a silica powder of 325 mesh. The ball-milled silica powder was diluted with 2 M NaOH at 90° for 2 hours and then filtered to get the sodium silicate solution (SSS). 2.2.2.
