Antimony–this metalloid element occurs in nature as a sulfide ore (stibnite – Sb2S3). Once purified, antimony was called regulus in medieval times, or earlier in history, flowers of antimony . Both purified antimony and stibnite are employed at specific phases in the archetypal synthesis.

Stibnite. Credit: D. Finnin, AMNH. One of the Museum's newest and most spectacular mineral specimens, a 1,000-pound stibnite with hundreds of sword-like, metallic blue-gray crystals sprouting from a rocky base, will go on display April 4. Stibnite (Sb2S3), a compound of the elements antimony and sulfur, occasionally forms nests of …
Estibnita é um sulfeto minerais com composição química é antimônio sulfeto (Sb2S3). O principal minério de antimônio. De cor cinza-chumbo a cinza prateado, muitas vezes desenvolve uma mancha preta iridescente quando exposta à luz. Normalmente ocorre como cristais prismáticos alongados que podem ser dobrados ou torcidos.

This study aimed to introduce a vacuum process for recovering and enriching antimony from low-grade stibnite. At the pressure of 10 Pa, by controlling heating temperature, Sb 2 S 3 and Sb 2 O 3 from stibnite (12.8 wt% Sb) was evaporated and enriched. We investigated the influence of vacuum distillation temperature and time on …
Sb2S3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Sb2S3 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded to five S2- atoms to form SbS5 square pyramids that share corners with two equivalent SbS6 …

Stibnite is an antimony trisulphide mineral with the chemical formula Sb2S3. It is a natural mineral source of the chemical element antimony (Sb), which is a lustrous grey metalloid, and it is mined primarily for this reason. Dioscorides, the Roman naturalist and the father of pharmacy, refers to stibnite as πλατυόφθαλμον ...
Orthorhombic Sb2S3 (stibnite) and its amorphous Sb2S3/C composite were synthesized by solid-state routes, such as heat treatment and high energy mechanical milling (HEMM).

Raman spectroscopy was conducted to investigate the variation of G/Sb 2 S 3 composite and stibnite. As shown in Fig. 1c, the typical peaks of Sb 2 S 3 were located at the range from 100 to 600 cm −1, and two obvious and intense peaks corresponding to the D-band and G-band of the graphite were observed.The peak at 1354 cm −1 was ascribed to the …
La stibnite Sb2S3 è un minerale, un solfuro di antimonio. Sono suoi sinonimi antimonite e stibina. Il nome stibnite deriva da stibio, voce desueta per antimonio, e (antimo)nite. Il nome stibina deriva dal greco στίβι = nero-antimonio, conosciuto già nell'antichità. Il nome antimonite deriva forse dall'arabo 'utmud.

Stibnite (Sb2S3), the principal natural source of Sb in the environment, is linked to the parent weathering material of sinarmonitis (cubic Sb2 O 3 ), stibiconite (Sb 3 O 6 OH), and valentinitis (orthorhombic Sb 2 O 3) ( Hu, Guo, He, & Li, 2016 ). It has been calculated that volcanic activity is responsible for 3%–5% of worldwide Sb emissions ...
