Abstract. The term ceramics is used to denote those products made from inorganic materials and which have non-metallic properties. Simple examples are ionically bonded magnesia, MgO, and covalently bonded silicon carbide, SiC, which crystallize in the cubic structures of sodium chloride (fig. 4.21) and diamond (fig. 4.20), respectively.
They can further be classified into thermoset composites, thermoplastics composites and natural fiber composites. 1.2.1 Metal Matrix Composite (MMC) Metal matrix composite (MMC) consists of a metallic matrix and reinforcement of metal (lead, tungsten, molybdenum) or ceramic (oxides, carbides). Matrix materials used generally are …

The Monkton deposit, discovered in 1792, was first mined in the mid 1800s. The American Kaolin Company produced about 2,000 tons per year between 1883 and 1890. The deposit was later utilized for raw material for the Rutland Fire Clay Company from 1930 to 1944. In 1956, the deposit was purchased by Vermont Kaolin.

Despite non-metallic inclusions comprising a small fraction of the total steel volume, they have a major effect on the mechanical properties.
Lustre is the reflection of light off the surface of a mineral. Mineralogists use specific terminology to explain lustre. The mineral's metallic or non-metallic status is one easy way to classify lustre. Minerals with a metallic lustre, such as pyrite, are opaque and shiny. Quartz, for example, has a nonmetallic lustre.
