Titanium graphite

The microstructure of the initial titanium-graphite mixture is shown in Figure 62a. When the temperature in the combustion wave reaches 1660°C, titanium melts. It was determined from quenching results that a thin film ( 0.1 / m) of the Ti melt spreads over the solid carbon surface with simultaneous formation of titanium carbide grains (Fig. 62b). Small rounded TiC particles were observed to appear within the liquid rather than in the form of a continuous product layer (Rogachev et al, 1987). To illustrate this fact further, the typical microstructure formed during combustion reaction of titanium melts with graphite whiskers (10 /.im in diameter) is shown in Fig. 62c. 

The cathode material is usually stainless steel, a nickel alloy, or titanium. Graphite, lead dioxide, platinized titanium, and DSA are some of the materials that have been used as an anode. The cells are operated at a current density of between 0.1 and 0.5 A/cm. The majority of the cells used to produce hypochlorite have the parallel-plate type of geometry [81]. 

Several variations of this exceedingly important reaction have been reported in recent years, e.g. the use of titanium-graphite from Ti(III) and CgK, especially...

Reductive cyclization of o-acylanilides by low-valent titanium has recently been explored as a method of synthesis of indoles <9215991,93CC211,94CB1125>. The reaction is most conveniently carried out using titanium-graphite. In addition to alkyl and aryl substituents, examples of cyclization with R being styryl, acetyl and ethoxycarbonyl were successful (Equation (20)).
