According to Laver (1997), titaniiun white has been apphed to any white pigment containing titanium. These may include barium titanate, zinc titanate, potassium titanate (qq.v), titanium hthopone, titanium phthalate and titanium silicate. Titanium dioxide white is also a titanium white. Furthermore, die name permanent white (q.v.) has been apphed to these (and other) compounds. 

X-ray Diffraction Analysis. The inorganic components of paper are the most suitable ones for quantitative X-ray diffraction analysis. Most of these compounds are minerals and are present as fillers, coatings and pigments (often whiteners) which are added to improve the properties of the paper. Examples of compounds commonly added to paper are alumina, aluminum silicate, barium sulfate, calcium carbonate, calcium sulfate, calcium sul-foaluminate, iron oxide, magnesium silicate, silica, titanium dioxide, zinc oxide, and zinc sulfide (28). Some of these, e.g., calcium carbonate and titanium dioxide, may be present in any of... 

Metal salts may be used in the treatment of wool. Flame methods for the determination of aluminium [185], barium, chromium, copper, mercury, strontium, tin, zinc [186] and zirconium [187] in wool have been published. Standard additions to wool cleaned by soaking and washing it with disodium EDTA (800 ml of 0.5 M for 30g wool with soaking for 3 days and double washing) was used as the calibration technique. This compensated for interferences from hydrochloric acid and amino-acids. The samples were equilibrated to a constant humidity for 24 h and then 0.3 g sealed with 5 ml of constant boiling point hydrochloric acid in a glass tube. The tubes were placed in an oven at 110UC for 20 h. The nitrous oxide/acetylene flame was used for the determination of aluminium and zirconium. Sulphate, phosphate, citrate and silicate have been found to interfere in the determination of titanium and zirconium in fire-proofed wool [188], These flame... 

Insoluble solids, regardless of particle size, that have a relatively low interfacial tension and are readily wetted by water are called hydrophilic solids. These solids include clays (bentonite, kaolin, talc, magnesium aluminum silicate) bismuth salts, barium sulfate, carbonates, hydroxides, or oxides of calcium, magnesium, zinc, and aluminum and titanium dioxide. The hydro-philicity of a powder surface can be investigated with the help of moisture absorption studies in which the solid particles are exposed to varying relative humidities. Insoluble powders that absorb moisture below relative humidities of 70-80% at room temperature are said to be hydrophilic solids.

Rubber compounds can contain a range of fillers such as silicates, sulphates, oxides, carbonates, phosphates, nitrates, titanium dioxide, barium sulphate and various clays. Analysis of mixtures of these additives is complicated and it is necessary to separate the constituents by dissolution in suitable inorganic solvents and/or filtration of insoluble substances such as silicates. The residues can be examined in several ways ... 

The trimethylsilylated silicic acids formed in this instance are soluble in conventional organic solvents, and their volatility is sufficiently high for them to be analysed by gas chromatography. Carzo and Hoebbel [411] carried out a comprehensive study of the chromatographic retention of various trimethylsilylated silicic acids on different stationary phases Apiezon L and silicone OV-1 and OV-17. The analysis of metals in the form of volatile complexes continues to attract attention, and have been described for analysing sodium [412], potassium [412], radium [413], caesium [413], barium [414], calcium [414], strontium [415], beryllium [416, 417], magnesium [418], zinc [419, 420], nickel [419], mercury [421], copper [422, 423], silver [424, 425], cadmium [421], indium [426, 427], g ium [428], scandium [217], cobalt [421], thallium [426], hafnium [429, 430], lead [431, 432], titanium [430], vanadium [433], chromium [434-436], manganese [426], iron [437], yttrium [438], platinum [439,440], palladium [439, 441, 442], zirconium [430], molybdenum [443], ruthenium [444], rhodium [445], rare earths [446—449], thorium [221, 450, 451] and uranium [221, 452].

Extensive chemical analyses on coals have shown that elements with relatively large ranges of concentrations (e.g., arsenic, As barium, Ba cadmium, Cd iodine, I lead, Pb antimony Sb and zinc, Zn) include those that are found in coals within sulfate and sulfide minerals. In addition, many elements appear to be positively correlated in coals such as calcium and manganese, zinc and cadmium, the chalcophile elements (i.e those elements which commonly form sulfides, such as cobalt, Co nickel, Ni lead, Pb and antimony, Sb) and the lithophile elements (i.e., those elements which commonly occur in silicate phases, such as silicon. Si titanium, Ti aluminum, Al and potassium, K).

Silicates, silicic acid, calcium carbonate or barium sulfate are used as fillers. Silicates and silicic acid make rubber more sustainable. Colourings for rubber are for example titanium dioxide and iron oxides. It is better to avoid organic colourings due to the chance of migration of the colouring to the rubber surface, followed by migration into the preparation. 

Light-colored fillers do play an important role in NBR compounding, especially in the roller business. The main types of non-black fillers used with nitrile rubber are silica, silicate, clay, talc, and calcium carbonate. In addition there are many specialty light-colored fillers such as diatomaceous earth, barium sulfate, titanium dioxide, aluminum trioxide, antimony trioxide, magnesium hydroxide, and zinc oxide to name a few.

Primers are highly pigmented systems, containing titanium dioxide in combination with extender pigments such as silicates or barium sulfate, carefully selected to improve the paint attributes (leveling, sanding, humidity resistance). UV absorbers and HALS stabilizers can be added to improve UV resistance. The pH of the system is maintained between 7 and 8. 

Fillers reinforce and increase the volume of the sealant. Fillers also reduce formulation costs and affect the technical properties of the sealant itself Common fillers for sealants are calcium carbonate (chalk), aluminum silicate (clay), barium sulfate and sihdc acids. Finely divided fillers, such as talc and Microdol 1, reduce the surface tack while simultaneously stiffening the film. Thixotropic fillers, for example fumed silica or Si02, improve the gunnabihty and reduce the sag of the compositions. Pigments are used to color sealants the white pigment used is usually titanium dioxide. 

Inorganic fillers, such as silica, silicates, barium sulphate and calcium carbonate, are used extensively in plastics and rubbers and to be effective these are usually incorporated at a level well in excess of 5%. This means that they can easily be quantified by TGA. Other inorganic compounds are also used in most products, and these include zinc oxide (a common co-agent used in the cure system of rubbers) and titanium dioxide (a popular weight pigment). In contrast to fillers, these additives are usually only added at levels below 5% but, given that the detection limit of TGA is around 0.5%, they can still be detected and a reasonably accurate quantification performed.
