    bentonite - Schlumberger Oilfield Glossary

    A clay mineral that is composed principally of three-layer clays, such as montmorillonite, and widely used as a mud additive for viscosity and filtration control. Commercial bentonite ores vary widely in amount and quality of the swelling clay, sodium montmorillonite. Ores of lower quality, those with more calcium-type montmorillonite, are treated during grinding by adding one or more of the ...

    Introduction to Clay Minerals & Soils

    Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earth's surface. They are found most often in shales, the most common type of sedimentary rock. In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil.

    Harmful Ingredients of Brick Lime. Excess lime melts the bricks and disfigures it. If CaCO 3 exists (in the purest form, i.e., if it contains at least 95% CaO) in lime-lump in brick clay, it converts into quicklime on burning. When these bricks come in contact with water, quicklime slakes and expands.

    Clay - Wikipedia

    Clay is a finely-grained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO 2), metal oxides (Al 2 O 3, MgO etc.) and organic matter. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure.

    How Temperature Changes Clay

    Before the glass-making oxides begin to melt, the clay particles will already stick to each other. Beginning at about 1650 F (900 C), the clay particles begin to fuse. This cementing process is called sintering. After the pottery has sintered, it is no longer truly clay but has become a ceramic material.
