Chrome Compounds Refractory Cements Refractory Materials
One major class of refractory cement additives is that of chrome compounds chrome flour chrome sand (chromite) and directly chromium (iii) oxide (chromia Cr 2 O 3). It is stated that 18 of all chromite is used for refractory purposes (9).

Chromite RefractoriesPrincipal
Chrome magnesite refractory bricks are produced from sintered magnesia and chrome ore that has refractory level. Content of chrome-magnesite refractory bricks is generally 15-35 Cr2O3 and 42-50 MgO whereas magnesite-chromite refractories contain at least 60 MgO and 8-18 Cr2O3. Bonding space between refractory grains is done with silicate.

Refractory- and metallurgical-type chromite ores Zambales
Jul 01 1986 · The Zambales ophiolite is the major source of chromite ore in the Philippines. The chromitites are concordant cumulates and are associated with distinct chromitite-bearing sequences within the mantle peridotites. Refractory and metallurgical chromite deposits are spatially separated and related to different lithologic associations which crystallized from different parental magmas.
