The ferrites are SFCA type and are formed by a solidliquid reaction between hematite and the Fe2O3·CaO melt, with the subsequent assimilation of SiO2 and Al2O3 in the melt. The gangue is composed of calcium, iron and magnesium silicates which are difficult to reduce, and come to form part of the slag in the BF.

Like blast furnace slag, steelmaking slag oxides are combined when cooled to form various forms of minerals common to both lime and silica based materials. Normally, steelmaking slags are mainly composed of calcium silicates, calcium aluminoferrites, and fused oxides of calcium, iron, magnesium, and manganese.

Silicoferrites of calcium and aluminium (SFCA) are desirable phases in a high quality iron ore sinter product. The effects of sintering temperature, CaO/SiO 2 ratio, sintering gas atmosphere and cooling procedure on the phase composition of sintered specimens from an industrial sinter blend were examined with focus on the formation of SFCA phases.

The purpose of this post is to briefly discuss the most common misunderstandings about natural and synthetic chemicals: 1. Synthetic chemicals are more toxic than natural chemicals. 2. Organically grown food is better for you because it''s all natural. 3. Synthetic copies of natural chemicals are not as good for you. Ronnith Nandy Follow Student

The entire bottom of the space shuttle was covered with armorlike tile that is formed from pure silica fibers. This tile was formed and heated to 2,200°F in a furnace, which allowed for a ceramic bond to form. The tile was made from QFiber™, which was placed into production in a whiteglove facility in Waterville, Ohio.
