Petroleum coke (PETroleum coke) is a product obtained by distilling crude oil through distillation to separate light and heavy oil, and then heavy oil undergoing thermal cracking. From the appearance of petroleum coke , coke is irregularly shaped, black lumps (or particles) of various sizes, metallic luster, and coke particles have a porous structure. The main elemental composition is carbon, which accounts for 80wt% The English abbreviation of Weight means the weight percentage content. 5WT% is equivalent to more than 50,000 PPM (PPM is in millions of content), and the rest are hydrogen, oxygen, nitrogen, sulfur and metal elements. http://www.ferroeast.com/know/petroleum-coke.html Petroleum coke has its unique physical, chemical and mechanical properties. It is a non-volatile carbon that generates heat, and volatiles and mineral impurities (sulfur, metal compounds, water, ash, etc.) determine the chemical properties of coke. Petroleum coke can be used in graphite, sm...

1.Silicon slag(off grade silicon) is a by-product when making silicon metal. 2.The silicon content is from 45% to 95%, and the rest are C, S, P, Al, SiO2, Fe, Ca etc. 3.The silicon slag is much cheaper than purity silicon metal, and has many industrial Application 1.Silicon Dross(offgrade silicon metal) is a good substitute for ferro silicon in steel making which has advantage in reducing the making cost. 2.The silicon slag powder can be made silicon briquette which has far and wide market at home and abroad. 3.Silicon Dross(offgrade silicon metal) is used as deoxidizer in steel making.
