A nucleophilic metal anion has been used as a reducing agent to create Zintl ion directly. [PPN]2[Fe2(CO)6(Te2)2] (169) has been synthesized by direct reaction of Na2[Fe(CO)4] with elemental tellurium.115 Although not structurally characterized by X-ray methods, the formulation of 169 is supported by several pieces of experimental evidence. It can react with itself or with the Zintl ions present to produce mixed-metal species. It reacts with iodomethane to yield [Fe2(CO)6(/z-TeMe)2] (170) (Fig. 56),... 

Tin-lead can be substituted for tin for other purposes, although the toxicity of lead limits the field of application. The corrosion resistance is usually no better than that of unalloyed tin, but there may be some saving of cost in applications such as wash-boilers and other vessels for non-potable liquids and light engineering components formed from sheet metal. Heavily coated teme-plates may be used for the fuel tanks of stoves and vehicles. 

Advancements in materitJs have been one of the most important factors in the development of corrosion-resistant automobiles. For automobile body and chassis parts, use of precoated sheet steel in critical areas, as demonstrated in Fig. 5, is one of the most effective methods of combating corrosion. Early on, hot dip gttlvanized steel and Zincro-metal coated steel were used to prevent perforation corrosion from the inside out in auto-body applications. Today a wide range of materi tls is used including hot dip and electrodeposited zinc, zinc-iron, zinc-nickel, and zinc-nickel/ organic composite coated steel. Other materials include aluminum and aluminum-zinc coated steels for exhaust systems and some structural components, teme (tin-lead) coated steel for fiiel tanks, and tin coated steel [23-25],...

A tellurium derivative [( BuC5H4)2Y( i-TeMe)]2 has been synthesized by reaction of metal with [( BuC3H4)2Y( X-Me)]2 (Beletskaya et al. 1993c). 

Adhesives recommended include epoxies, vinyl alcohol—vinyl acetate copolymer, polyvinyl alkyl ether, polyacrylate (carboxylic), polyurethane (two-part), epoxy-phenolics, silicones, and cyanoacrylates. The high-strength thermoset and alloy adhesives are rarely justified for bonding lead. Even when other properties recommend these adhesives, the designer should check to see whether some low-cost or easier-to-use adhesive is also suitable. An exception is teme (lead-coated steel). This is a much stronger metal than lead, and lap-shear strengths exceeding 2.1 MPa are reported for adhesive joints with teme.° ... 

Formation and reduction of a hydrous oxide film on platinum resulted in an increase in the charge for monolayer oxide reduction in subsequent experiments. " Obviously the metal surface was roughened as a result of formation and subsequent reduction of the phas, pxide. However, the roughness developed with this technique teMed to decay under open-circuit conditions (a process that was accelerated by occasional potential sweeps for monitoring purposes). Such decay was more rapid than with platinum black deposits prepared from conventional chloroplatinic add baths— evidence perhaps that in the former case the active metallic layer is of a more highly strained, finely divided character. ...
