Absolute ethanol
Manufactured by Xilong
Sourced in China
Absolute ethanol, also known as 100% ethanol, is a clear, colorless liquid. It serves as a primary solvent for various laboratory applications, including chemical reactions, sample preparation, and cleaning procedures. Absolute ethanol has a high purity level, typically containing no more than 1% water.

C3S and Fe-doped tricalcium silicate (Fe/C3S) powders were synthesized by sol–gel method [27 (link)]. Briefly, 2-M nitric acid solution (HNO3, as a catalyst), absolute ethanol (C2H5OH, as a solvent), calcium nitrate tetrahydrate (Ca(NO3)2·4H2O, XiLong Chemical Co., Ltd., Shantou, China) and ferric nitrate nonahydrate (Fe(NO3)3·9H2O, Saan Chemical Technology Co., Ltd., Shanghai, China) were sequentially added to tetraethyl orthosilicate (TEOS, Sinopharm group Co., Ltd., Shanghai, China). Then, it was stirred well for 1 h. The molar ratio of TEOS-HNO3-C2H5OH was 10:10:1. The iron ion accounted for 0, 2.5, 5 and 10 mol% of the total metal cation concentration, respectively. Then, the above mixed solution was aged at 60 °C for 48 h, followed by drying for 48 h at 120 °C. Next, the gel was heated to 1450 °C at a rate of 5 °C/min, and then kept in a high temperature resistance furnace for 8 h. Finally, the sintered powder was finely ground in an agate mortar and sieved with a 300 mesh for further studies.

+ Expand
The laser particle size analyzer (GSL-1000, Liaoning instrument research institute Co., ltd., China) was used to measure the particle size distribution of the graphite ore. In the laser particle size analyses, absolute ethanol (analytical reagent, Xilong Scientific Co., ltd.) was used as a solvent to avoid the agglomeration phenomenon. The detailed operating processing of the particle size measurement has been previously described [5 ].
The chemical characterizations of raw ore and leaching concentrates were measured by XRD (6100, Shimadzu Corporation, Japan). XRD experiment was carried out at a 40 kV accelerating voltage and 30 mA current using a Cu Kα radiation source. The morphology characterizations and the impurity distribution of these samples were measured by SEM-EDS (FIB-SEM, Helios G4 CX, Thermo Fisher Scientific). The SEM and EDS images were synthesized to make the results more distinct. TEM-SEM analysis was carried out in a 200 kV transmission electron microscope (Talos F200S G2, Thermo Fischer Scientific) with a Super-X energy dispersive spectrometer system at a vacuum of 1.6 × 10-7 Pa. The detailed measurement processes of XRD, SEM-EDS, and TEM-EDS can be found in the literature [[62] , [63] ].

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
