As described in the previous section, the smaller change of the TBOP of Li ion with the movement through the conduction path was observed in the Li3N crystal. In this section, we have tried to estimate the relationship between the ionic conductivity and chemical bonding of the moving Li ions in the sulfide-based superionic conducting glasses.

The phase separation process of slag sital is characterized by the fact that the base glasses demonstrate substantial liquid-liquid phase separation as a result of the high P2O5 content. This type of phase separation in the base glasses, which was determined by Pavluskin (1986) with scanning electron microscopy, is more strongly influenced by the phosphate additives than by the sulfides. Hence, the phospates are of particular importance for the entire nucleation procedure and for the formation of crystals. 

Most sulfide glasses for optical applications are based on the As-S and Ge-S systems, with compositions modified by other metal or non-metal sulfides. These glasses are IR-transmitting materials which can also be used as rare-earth ion hosts for optical amplifiers.

Other early match-like devices were based on the property of various combustible substances mixed with potassium chlorate to ignite when moistened with strong acid. More important was the property of chlorates to form mixtures with combustibles of low ignition point which were ignited by friction (John Walker, 1827). However, such matches containing essentially potassium chlorate, antimony sulfide, and later sulfur (lucifers), mbbed within a fold of glass powder-coated paper, were hard to initiate and unreHable. 

Zinc compounds are generally colorless unless the other component, eg, chromate, is colored. The lack of color of most zinc compounds in visible light is a great advantage in that they do not color paint films, plastics, mbber, cosmetics, etc. However, when excited by various types of radiation and at various temperatures, zinc oxide, sulfide, selenide [1315-09-9], and related compounds exhibit luminescence, ie, they emit colored light (see Luminescent materials). Zinc-based phosphors can be produced in many colors, depending upon the added dopants. They are used in television tubes, luminescent glasses, and various specialty products. 

Other modifications of the polyamines include limited addition of alkylene oxide to yield the corresponding hydroxyalkyl derivatives (225) and cyanoethylation of DETA or TETA, usuaHy by reaction with acrylonitrile [107-13-1/, to give derivatives providing longer pot Hfe and better wetting of glass (226). Also included are ketimines, made by the reaction of EDA with acetone for example. These derivatives can also be hydrogenated, as in the case of the equimolar adducts of DETA and methyl isobutyl ketone [108-10-1] or methyl isoamyl ketone [110-12-3] (221 or used as is to provide moisture cure performance. Mannich bases prepared from a phenol, formaldehyde and a polyamine are also used, such as the hardener prepared from cresol, DETA, and formaldehyde (228). Other modifications of polyamines for use as epoxy hardeners include reaction with aldehydes (229), epoxidized fatty nitriles (230), aromatic monoisocyanates (231), or propylene sulfide [1072-43-1] (232). 

Claisse40 has made a comprehensive attack on mineral analysis. He realized that fusion to give a glass disk could be used at once to remove Class II deviations. (7.8) and to give samples in which a (Equation 6-6) varies very little from one sample to another. Accordingly, he developed the fusion of minerals (other than sulfide minerals) with fluxes based on borax (100 mg of sample to 10 grams of borax) when graphite or sulfides are present, oxidation must precede the borax fusion. Internal standards or materials intended to fix the value of a may be added before... 

The formation of colloidal sulfur occurring in the aqueous, either alkaline or acidic, solutions comprises a serious drawback for the deposits quality. Saloniemi et al. [206] attempted to circumvent this problem and to avoid also the use of a lead substrate needed in the case of anodic formation, by devising a cyclic electrochemical technique including alternate cathodic and anodic reactions. Their method was based on fast cycling of the substrate (TO/glass) potential in an alkaline (pH 8.5) solution of sodium sulfide, Pb(II), and EDTA, between two values with a symmetric triangle wave shape. At cathodic potentials, Pb(EDTA)2 reduced to Pb, and at anodic potentials Pb reoxidized and reacted with sulfide instead of EDTA or hydroxide ions. Films electrodeposited in the optimized potential region were stoichiometric and with a random polycrystalline RS structure. The authors noticed that cyclic deposition also occurs from an acidic solution, but the problem of colloidal sulfur formation remains. 

Figure 5.1 Made with three connected glass bowls, Kipp s apparatus relies on acid-base chemistry in order to produce gasses—such as carbon dioxide, hydrogen, or hydrogen sulfide—for chemists to use in other chemical reactions.

The filtrate is then warmed to room temperature, and hydrogen sulfide is bubbled into the solution until no more silver sulfide precipitates. This solid is separated by filtration through a medium-porosity, sintered-glass frit also connected to a previously evacuated, nitrogen-purged, and ice-salt-cooled 500-mL, two-necked, round-bottomed flask bearing an adapter fitted with a 2-mm vacuum stopcock. The filtrate is warmed to room temperature, and the stirred solution is evaporated under vacuum to give a solid product, which is further dried for another 1 lA hours. The yellow-brown crystalline solid, mp 4345°, is crude dihydro(isocyano)(trimethylamine)boron. Yield 16.0 g (75.8% based on trimethylamine-borane).

Zinc oxide (ZnO), which is produced by burning zinc vapor in atmospheric oxygen, is by far the most important compound of zinc. Under the name of zinc white, the oxide is used as a paint pigment. It is also used as a base in the manufacture of enamels and glass, and as a ruler in the fabrication of automobile tires and other kinds of rubber goods. Zinc sulfide (ZnS) is also an important white paint pigment which is used either as such or in the form of lithopone, which is a mixture of zinc sulfide and barium sulfate. This widely used pigment is prepared by the metathetical reaction between zinc sulfate and barium sulfide, a reaction in which both of the products are insoluble ...
