Colour inorganic compounds

Rubber is vulcanised by treatment with sulphur chloride or by heating with sulphur. In most cases, however, rubber articles are made, not of pure vulcanised rubber, but of the latter mixed with various other substances, organic and inorganic. The organic substances more commonly used are brown and white factis, fatty oils, oxidised oils, waxes, mineral oils, paraffin wax or ceresine, resin or resin oils, bitumens, tar, pitch, starch, and artificial dyes. Very many inorganic compounds may be added either as fillers or to give colour, e.g., talc, kaolin, asbestos, chalk, gypsum, lime. [Pg.325]

A review of spectrophotometric methods for tellurium determination has been presented [3]. The systems employing inorganic compounds forming coloured products, N-... [Pg.507]

Colorants. Addition of soluble dyes and the dispersion of pigments are the methods used to provide plastics with desired colours. Dyes include azo compounds, anthraquinones, xanthenes and azines whereas a variety of inorganic compounds are used as pigments such as iron oxides, cadmium and titanium dioxide. [Pg.12]

This property is known for solids as well as liquids. Known examples for deflagrating solids are fi-ee radical initiators such as Azo-isobutyronitrile (AIBN), colour pigments like pigment orange Cl 12075, or inorganic compounds such as hy-droxylammonium sulfate [40]. Some organic peroxides are known examples for liquids having this property [41]. [Pg.66]

The topics chosen for inclusion in this chapter reflect areas of active interest and elaborate upon some topics that have been given only brief mention in earlier chapters. In describing the chemistries of the d- and /-block metals in Chapters 22, 23 and 25, we included many examples of solid state compounds, and we now look further at electrical conducting and superconducting properties. At various points in the book, we have mentioned colour pigments in ceramic materials when describing applications of inorganic compounds (mainly... [Pg.938]

Materials which undergo optical (colour) changes when exposed to a current or when immersed in an electric field are called electrochromic materials (ECMs). Although an electrochromic effect may be shown by a variety of materials, the most studied ECMs are ion insertion inorganic compounds and organic conducting polymers. [Pg.251]

The colours of inorganic compounds, as with organic molecules, are due to transitions between electronic energy levels as a result of the absorption of visible light. Several different mechanisms may be involved, as discussed in this section. [Pg.66]

All methods for the determination of inorganic phosphate in seawater are based on the reaction of the ions with an acidified molybdate reagent to yield a phosphomolybdate heteropoly acid, which is then reduced to a highly coloured blue compound. In early work, tin(//) chloride was used as the reductant in flow-analysis (Hager et al, 1968). However, this reductant has several disadvantages, including the appreciable temperature dependence of the reduction rate and the pronounced salt error. [Pg.170]
