Magnesia-chrome bricks

Refractories. Aluminosilicates, silica and aluminous material, basic materials such as magnesite, chrome-bearing materials such as magnesia-chrome bricks, zirconia-bearing materials, and silicon carbide. There are also raw materials such as fireclay, ferrosilicon, and graphite. [Pg.503]

Refractory-grade chromite is used for manufacturing magnesia-chrome bricks used in the extractive metallurgy of platinum group metals. Foundry sands made of chromite fines are used for making mould used for casting nonferrous metals. [Pg.372]

Cbrome bricks are manufactured in much the same way as magnesite bricks but are made from natural chromite ore. Commercial ores always contain magnesia and alumina. Unburned hydraulically pressed chrome bricks are also available. [Pg.2472]

Chrome brick is made fromnaturally occurring chrome ore. It contains 34% AI2O3 and 30% Cr203. Often MgO is added to produce chrome-magnesia brick. [Pg.146]

Photograph 7-58 Belite striations in light blue alite. Multicolored, round belite showing typical lamellae, but somewhat scalloped cross section. Small secondary belite in brightly reflecting ferrite matrix. Clinker sample contains remnants of chrome-magnesia refractory brick. (S A6678)... [Pg.99]

Photograph 7-70 Strongly pleochroic red ferrite in clinker containing partially consumed chrome-magnesia refractory brick (not shown). Belite with abundant exsolved impurities. Belite crystals in other parts of this clinker nodule are pale green. (S A6688)... [Pg.105]
