A polycrystalline ingot of PbS was synthesized
by mixing a stoichiometric ratio of high purity Pb granules (99.999%,
Alfa Aesar) and S powder (99.999%, Alfa Aesar) in a vacuum-sealed
quartz ampoule, followed by reacting them at 1373 K to produce a high-purity
PbS starting material. Polycrystalline ingots of Pb_1–xNa_xSe_0.35S_0.1Te_0.55 with x = 0.01, 0.02,
0.03, and 0.035 were prepared by mixing appropriate quantities of
the PbS precursor, Pb, Se granules (99.999%, Alfa Aesar), Te powder
(99.999%, Alfa Aesar), and crushed Na chunks (99%, Aldrich) as the
dopant, with a total mass of 10 g for each sample, loaded into carbon-coated
quartz ampoules. The ampoules were sealed under vacuum, then heated
to 1373 K, and held at the same temperature for 10 h. The ampoules
were then quenched in cold water and annealed at 823 K for 72 h.

Check if the same lab product or an alternative is used in the 5 most similar protocols

Single crystals of AuTe₂Se_4/3 were grown using the self-flux method. Total 2–4 g starting materials with high purity Au powder (99.99%, Sigma Aldrich), Te powder (99.999%, Sigma Aldrich), and Se powder (99.99%, Sigma Aldrich) were stoichiometrically weighted and sealed in an evacuated silica tube in high vacuum (10⁻⁵ mbar) and subsequently mounted into a muffle furnace. The furnace was heated up to 800 °C in 40 h and dwelled 10 h. Afterward, the furnace was slowly cooled down to 450 °C in 4 days and then shut down. Separated crystals from ingot are generally thin with maximum planar size 4 × 1 mm². The single crystals of AuTe₂Se_4/3 were ribbon shape with shining mirror-like surfaces.

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.
