Blue lead

Lead sulfide is used in photoconductive cells, infrared detectors, transistors, humidity sensors in rockets, catalysts for removing mercaptans from petroleum distillates, mirror coatings to limit reflectivity, high temperature solid-film lubricants, and in blue lead pigments (82). [Pg.69]

Most black pigments are made of carbon black formed by depositing carbon from a smoky flame of natural gas on a metal surface. Lampblack is made similarly by burning oik Bone blacks are made from charred bones. Graphite occurs naturally or can be prepared from coal in electric furnaces. Mineral blacks come from shale, peat, and coal dust. Iron oxide blacks are found in nature or prepared. Blue lead sulfate is a pigment for priming. Of these, carbon black is su[XTinr. [Pg.284]

With methylthymol blue, lead may be titrated at a pH of 6 without interference by calcium the calcium is subsequently titrated at pH 12. [Pg.333]

When metals are oxidized, paint pigments are produced. Iron oxide is a red pigment copper oxide is blue lead oxide is yellow. [Pg.107]

Free Halogens Combine 10 mL of sample with 10 mL of a 1 10 potassium iodide solution and 1 mL of starch TS, and shake vigorously for 2 min. The water layer does not turn blue. Lead Determine as directed for Method II in the Atomic Absorption Spectrophotometric Graphite Furnace Method under Lead Limit Test, Appendix IIIB. [Pg.488]

Several interesting systems for the cyclic cleavage of water have appeared and all require close scrutiny. The use of Prussian Blue as an O2- and Hi-evolving catalyst seems feasible because of its cluster-type structure, and it has been reported that irradiation of tris-(2,2 -bipyridyl)ruthenium(ii) in water (pH 2) containing Prussian Blue leads to... [Pg.539]

Mechanisms 1 - 3 have different stereochemical outcomes and can be distinguished on the basis of labelling experiments. Scheme 15 shows how mechanism 1 (blue) leads to a scrambling of the label between two locations, mechanism 2 (red) does not result in the change of position of the labels, and mechanism 3 (green) results in the transposition of one of the labels to the opposite side of the molecule. To realize this labelling experiment in practice we performed separate isomerization reactions of... [Pg.90]

A silver lustre for artware similar in appearance to the lustre on the wings of the cantharides beetle it is yellow and has usually been applied to a blue lead-glaze. [Pg.49]

Fig. 8 The compression (right) of a charged polymer (yellow area with black chains positively charged) containing mobile ions and in contact with an electrolyte (Ught blue) leads to the expulsion of ions and the generation of a potential due to the separation of charge at the interface. The expulsion may be the result of imbalance in concentration (Donnan potential) or elastie forces squeezing the ions out...

Also included here are the secondary oxides (aluminates) calcium aluminate (CaAl204), cobalt aluminate (C0AI2O4), lead aluminate (PbAl204) and hercynite (iron aluminate, Fe Al204). Calcium aluminate (calciiun aluminium oxide) may be a component of the pigment known as Satin white. Cobalt aluminate (cobalt aluminium oxide) is the pigment Cobalt blue. Lead alu-minate is listed by the Colour Index (1971) under Cl 77585. Hercynite has been identified on Minoan painted pottery by Stos-Fertner et al. (1979). Chromium aluminium cobalt oxide is Turkish Green. [Pg.8]
