volcanic origin. Since then scientists have found ways to make diamond from graphite and other synthetic materials. Diamonds of true gem quality are not made in this way . Graphite is another form of carbon. It occurs as a mineral in nature‚ but it can be made artificially from amorphous carbon. One of the main uses for graphite is for its lubricating qualities. Another is for the "lead" in pencils. Graphite is used as a heat resistant material and an electricity conductor. Amorphous

Executive Summary American Chemical Corporation’s Collinsville plant in Alabama is being sought by Dixon a speciality chemicals company. This plant mainly specialises in Sodium Chlorate production and fits well with Dixon’s strategy of supplying chemicals to paper and pulp industry. It would also complement Dixon’s existing product line. The plant costs $12million in investment and requires up to$ 2.25 million for upgrading to new technology. An in-depth investigation and analysis is conducted

pearlite‚ in grains of cementite‚ or in scattered small particles of carbide. In cast iron‚ most of the carbon is usually present in uncombined form‚ as graphite. (Graphite is one of the two crystalline forms of carbon; diamond is the other). The differences between the general types of cast iron most widely used arise chiefly from the form which the graphite assumes in the finished iron. Gray Iron. Of the general types of cast iron‚ gray iron is by far the most widely used. The term ”gray iron” was adopted

Common materials used for engine blocks include Grey Cast Iron‚ aluminum and Compacted Graphite Iron (CGI). In the early years of building engine blocks‚ grey cast iron was the only material used. The process of using alloys was non-existent and aluminum was a new material which few people were familiar with. At the time‚ however‚ grey cast iron worked very well. The carbon‚ present as flakes of graphite‚ in grey cast iron gives the material good resistance to wear and also provides good corrosion

conductive concrete with both superior electrical conductivity and mechanical properties. Electrically conductive concrete is a functional composite that is composed of regular concrete and a certain amount of electrically conductive components like graphite‚ carbon fibers etc. Adding appropriate electrically conductive components into concrete can improve the electrical conductivity greatly and it becomes a good conductor. When connected to an outer power source‚ heat is generated in an electrically

Reactor 4 was a RBMK (an acronym derived from the Russian initials for heterogeneous‚ water-graphite channeltype reactor)‚ which uses graphite as a "moderator‚" i.e.‚ to slow down neutrons and thereby sustain the nuclear chain reaction. Events Leading to the Accident Saturday April 26‚ 1986 During the shutdown a test was to be run to see if the slowing turbine
