Cordierite or iolite is a magnesium iron aluminium cyclosilicate. Iron is almost always present, and a solid solution exists between Mg-rich cordierite and Fe-rich sekaninaite with a series formula: ( Mg , Fe ) 2 Al 3 ( Si 5 Al O 18 ) to (Fe,Mg) 2 Al 3 (Si 5 AlO 18 ) . [ 3 ]
Gunpowder, an explosive mixture of sulfur, charcoal and potassium nitrate (also known as saltpeter), was the original propellant employed in firearms and fireworks.It was used from about the 10th or 11th century onward, but it had disadvantages, including the large amount of smoke it produced.
Cordierites is a genus of fungi in the family Cordieritidaceae.. The genus name of Cordierites is in honour of François Simon Cordier (1797-1874), a French military doctor and botanist (Mycology), he was a founder member and president of the Société botanique de France in 1872.
Cordierite Diesel Particulate Filter on GM 7.8 Isuzu. Unlike a catalytic converter which is a flow-through device, a DPF retains bigger exhaust gas particles by forcing the gas to flow through the filter material before exiting; [2] [29] however, the DPF does not retain small particles. Maintenance-free DPFs oxidise or burn larger particles ...
Cordierite – (Mg,Fe) 2 Al 4 Si 5 O 18; Sekaninaite – (Fe +2,Mg) 2 Al 4 Si 5 O 18; 9-member single ring Eudialyte – Na 15 Ca 6 (Fe,Mn) 3 Zr 3 SiO(O,OH,H 2 O) 3 (Si 3 O 9) 2 (Si 9 O 27) 2 (OH,Cl) 2; 6-member double ring Milarite – K 2 Ca 4 Al 2 Be 4 (Si 24 O 60)H 2 O; The ring in axinite contains two B and four Si tetrahedra and is highly ...
Monoliths for automotive catalytic converters are made of a ceramic that contains a large proportion of synthetic cordierite, 2MgO•2Al 2 O 3 •5SiO 2, which has a low coefficient of thermal expansion. [1] Each monolith contains thousands of parallel channels or holes, which are defined by many thin walls, in a honeycomb structure.
Sekaninaite ((Fe +2,Mg) 2 Al 4 Si 5 O 18) is a silicate mineral, the iron-rich analogue of cordierite.. It was first described in 1968 for an occurrence in Dolní Bory, Vysočina Region, Moravia, Czech Republic, and is now known also from Ireland, Japan, and Sweden.
Refractory bricks in a torpedo car used for hauling molten iron. In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures. [1]
