What Are The Physical And Chemical Properties Of Sand

Apr 04, 2020 Sand is composed of all kinds of rocks and minerals, so its chemical properties greatly vary. Most sand is made of quartz, which is largely silicon oxide. Physically, sand is made up of tiny, loose grains of rocks or minerals that are larger than silt but smaller than gravel. Quartz is a very hard mineral, ranking a 7 on the Mohs hardness scale.

Silica fume is a by-product of the production of silicon metal or ferro-silicon alloys in electric blast furnaces. In these processes, silica sand (quartz) is fed into the blast furnace with coke, coal and wood chips. These materials are reacted at temperatures of about 2000 C to produce the silicon product, with very fine silica fume.
