Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS2 and structure S=C=S. It is also considered as the anhydride of thiocarbonic acid. [8] . It is a colorless, flammable, neurotoxic liquid that is used as a building block in organic synthesis.

Oct 5, 2018 · CS2 is an abbreviated form of Carbon Disulphide. This molecule has two Sulphur atoms and one Carbon atom. To understand the hybridization, molecular geometry and the polarity of this molecule it is essential to under its Lewis structure.

Dec 15, 2021 · According to the CS2 Lewis structure, carbon is the central atom with zero lone pair of electrons and two sulphur atoms attached to it. Therefore, the space number = 0 + 2, …

C2S has five polymorphic forms denoted as γ, β, α ′L, α ′H, and α in the temperature range between room temperature and 1500°C [7]. The C2S phase usually found in clinker is the β monoclinic one [8].

Belite is an industrial mineral important in Portland cement manufacture. Its main constituent is dicalcium silicate, Ca 2 SiO 4, sometimes formulated as 2 CaO · SiO 2 (C 2 S in cement chemist notation). The name was given by Alfred Elis Törnebohm in 1897 to a crystal identified in microscopic investigation of Portland cement. [1] .

β-dicalcium silicate (β-Ca2SiO4 or β-C2S in cement chemistry notation) is one of the most important minerals in cement. An improvement of its hydration rate would be the key point for...

NIST subscription sites provide data under the NIST Standard Reference Data Program, but require an annual fee to access. The purpose of the fee is to recover costs associated with the development of data collections included in such sites. Your institution may already be a subscriber.

Mar 5, 2025 · Based on simulation results, the carbonation activity of the three C 2 S polymorphs was inferred to follow the order of γ-C 2 S>α′ L -C 2 S>β-C 2 S, which was verified by experimental measurement of carbonation heat release and CO 2 sequestration amount.

Jul 1, 2023 · Density Functional Theory was applied to obtain a refined IR and Raman theoretical vibrational spectra of the major silicate phases of Portland cement, i.e. dicalcium silicate (β-C2S) and tricalcium silicate (C3S).

Dec 20, 2022 · γ-C2S has high potential for use as a construction material with the additional benefit of CO2 absorption due to its high carbonation reactivity. This study quantitatively investigates the evolutio...
