Compressing aluminium sulfide to 2–65 kbar results in the δ phase where vacancies are arranged in a superlattice of tetragonal symmetry. Unlike Al 2 O 3, in which the Al(III) centers occupy octahedral holes, the more expanded framework of Al 2 S 3 stabilizes the Al(III) centers into one third of the tetrahedral holes of a hexagonally close-packed arrangement of the sulfide anions.
A slight stimulation mainly on the thymocytes was obtained with beryllium chloride, cadmium chloride, palladium chloride, platinum chloride and silver nitrate, at certain concentrations in the range of 10(-5)-10(-6)M, while ferric chloride gave a slight stimulation at 1.2 X 10(-3)M.

It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3) also known as hematite. It contains both Fe 2+ and Fe 3+ ions and is sometimes formulated as FeO ∙ Fe 2 O 3. This iron oxide is encountered in the laboratory as a black powder.
Lead(II) sulfide (also spelled sulphide) is an inorganic compound with the formula Pb S. PbS, also known as galena, is the principal ore, and most important compound of lead. It is a semiconducting material with niche uses.
