Promise as raw materials

Use of nonequilibrium systems as raw materials is also very promising for improving nitride ceramics quality. 

Nanofillers may be nanoclays, carbon nanotubes (single or multiwall) (CNTs), silica, layered double hydroxides (LDHs), metal oxides, etc., offering the promise of a variety of new composites, adhesives, coatings, and sealant materials with specific properties [32-37]. Among the fillers mentioned, nanoclays have attracted most of the academia and industry interest, due to their abrmdance as raw materials and to the fact that their dispersion in polymer matrices has been studied for decades [38]. In fact, there are three major polymer nanocomposites categories in terms of nanofiller type that are expected to compile the global nanocomposites market in 2011 nanoclay-reinforced (24%), metal oxide-reinforced (19%), and CNTs-reinforced (15%) ones [39-41]. 

The increase in the price of oil and natural gas motivates the chemical industry to develop processes that use alternative raw materials and to develop efficient and economical processes for liquid fuels synthesis from coal and natural gas. An innovative promising approach for producing gasoline from methane is presented in [5]. Other important tasks are development of efficient methods for producing liquid fuels from unconventional sources such as oil shale, tar sands, and deep-sea methane hydrates. 

Carbon capture and storage technology is the most promising technology to significantly decrease C02 emissions. Nevertheless, it may be possible to use C02 as a raw material for other industrial uses. In this chapter, authors explain both ways to decrease C02 emissions. 

Fine metal particles have received much attention in recent years from the viewpoints of chemical, physical, and biological interests (1-4). They are one of the most promising advanced materials. Compared with metal oxide or metal salts, metals have the highest electric and thermal conductivity, considerably higher weight and melting point, and usually excellent catalytic properties. These properties of metals cannot be replaced by other materials. Thus, even after the rapid growth of plastic, bulk metals keep their important position as one of the most common raw materials.
