High voltage insulators make it possible to safely carry electricity to houses and businesses. Fibre optic fibres have provided a technological breakthrough in the area of telecommunications. Using this technology has increased the speed and volume of information that can be carried by orders of magnitude over that which is possible using copper cable. The reliability of the transmitted information is also greatly improved with fibre optic fibres. In addition to these benefits, the negative effects of copper mining on the environment are reduced with the use of silica fibres.
Ceramics play an important role in addressing various environmental needs.
Ceramics help decrease pollution, capture toxic materials and encapsulate nuclear waste. Today's catalytic converters in vehicles are made of cellular ceramics and help convert noxious hydrocarbons and carbon monoxide gases into non-toxic carbon dioxide and water. Advanced ceramic components are starting to be used in diesel and automotive engines. Ceramics' light weight and high-temperature and wear resistant properties, results in more efficient combustion and significant fuel savings. Ceramics are also used in oil spill containment booms that corral oil so it can be towed away from ships, harbours, or offshore oil drilling rigs before being burned off safely.
