Uranium compounds are compounds formed by the element uranium (U). Although uranium is a radioactive actinide , its compounds are well studied due to its long half-life and its applications. It usually forms in the +4 and +6 oxidation states , although it can also form in other oxidation states.
Low-VOC paint types include latex (water-based), acrylic, and milk paint, with most relatively easy to recycle. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC.
Uranyl sulfate describes a family of inorganic compounds with the formula UO 2 SO 4 (H 2 O) n. These salts consist of sulfate, the uranyl ion, and water. They are lemon-yellow solids. Uranyl sulfates are intermediates in some extraction methods used for uranium ores. [1] These compounds can also take the form of an anhydrous salt.
Paris Green: It was manufactured in 1814 to be a pigment to make a vibrant green paint; Cadmium pigments. Cadmium green: a light green pigment consisting of a mixture of cadmium yellow (CdS) and chrome green (Cr 2 O 3). Chromium pigments. Chrome green (PG17): anhydrous chromium(III) oxide (Cr 2 O 3). Viridian (PG18): hydrated chromium(III ...
Yellowcake (also called urania) is a type of powdered uranium concentrate obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared by various extraction and ...
Lacquer is a solvent-based paint or varnish that produces an especially hard, durable finish. Usually it is a rapidly drying formulation. Enamel paint is formulated to give an especially hard, usually glossy, finish. Some enamel paints contain fine glass powder or metal flake instead of the color pigments in standard oil-based paints.
Under wet conditions, the mold Scopulariopsis brevicaulis produced significant amounts of methyl arsines via methylation [25] of arsenic-containing inorganic pigments, especially Paris green and Scheele's green. In these compounds, the arsenic is either pentavalent or trivalent (arsenic is in group 15), depending on the compound.
Uranyl nitrate is a water-soluble yellow uranium salt with the formula UO 2 (NO 3) 2 · n H 2 O.The hexa-, tri-, and dihydrates are known. [3] The compound is mainly of interest because it is an intermediate in the preparation of nuclear fuels.
