  • The effect of the gelation time in the chemical reaction to change the phase from sol to gel on the gel and quartz powder states was investigated by observing the absorbance spectra of the gels and powders at wavenumbers of 500–4000 cm−1. In the case of the gel state, four peaks appeared in the absorbance spectrum, i.e., a broad OH stretching peak at 3000–3700 cm−1 derived from the OH group, an OH bending peak at ~1640 cm−1, an asymmetric Si−O−Si stretching (VasSi−O−Si) peak at ~1075 cm−1, and a The gel-pulverizing process on the morphology of the as-synthesized quartz powders. Three hours after the ion exchange process, SiO2 sol was changed into a single lump of gel; when subjected to the gel-pulverizing process, the gel lump was separated into many gel lumps of several mm. In addition, the morphology of the quartz powder synthesized via the gel-pulverizing process was very different from that produced without the gel-pulverizing process, as is shown in the SEM images. The morphology o The water glass typically used in industry is synthesized using sodium and potassium silicate. In our experiment, as the selective adsorption of the strongly acidic cation exchange resin is greater when the valence of the ion is larger, the water glass was synthesized via a KOH solution rather than a NaOH solution to use a potassium ion with a relatively large valence in terms of efficiency. When synthesizing fumed silica-based quartz powder, we prepared a potassium silicate solution mixed with The transmittance spectra of potassium silicate solutions at wavelengths ranging from 300 to 1000 nm and at wavenumbers ranging from 500 to 2000 cm−1 were measured via UV–visible spectroscopy (Cary 5000, Agilent Technologies Co., Inc., Santa Clara, CA, USA) and Fourier-transform infrared spectroscopy (FT-IR, Nicolet iS50, Thermo Scientific Co., Inc., Waltham, MA, USA) with attenuated total reflection (ATR) mode, respectively. After the gelation process, the morphology and crystallinity of the tw The process involves preparing the potassium silicate solution, ion exchange, gelation, freezing, thawing, drying, cleaning, and sintering. First, 500 g of potassium silicate solution was prepared by mixing with six wt% fumed silica, 2.4 wt% KOH, and 91.6 wt% deionized water. The solution was poured into polypropylene (PP) bottles and placed on hotplates at 80 °C for 24 h under 300 rpm mechanical stirring via a magnetic stirrer. The experiment for the dependency of dissociation of fumed silica o we develop a novel fumed silica-based sol–gel process for synthesizing ultra-high-purity quartz powder to achieve the requirements of semiconductor technology with a design rule of 3 nm, i.e., a metal impurity level of less than 100 ppb and median size distribution (d50) of the powder of about 150–200 μm�m. In particular, the optimal process conditions for preparing potassium silicate solution, gelation time, and cleaning process of the as-synthesized quartz powder were determined by analyzing t Fumed silica-based ultra-high-purity synthetic quartz powder was developed via the sol–gel process to apply to quartz wares and quartz crucibles for use in advanced semiconductor processes. The process conditions of preparing potassium silicate solution, gelation, and cleaning were optimized, i.e., the relative ratio of fumed silica (10 wt%) to KOH (4 wt%) for potassium silicate gelation time of three h and cleaning for one h with five wt% HCl solution. It was observed that the gelation time str Quartz Powder is formed by the calcination of the smallest (SiO2) dust particles, which are formed due to the decomposition of the quartz-rich magmatic metamorphic rocks by calcination of high-purity quartz ore at 900 * C. It is an important raw material needed in many branches of industry and consumed in high amounts.
