Needle shaped coke
Needle coke is a high-quality variety that has been vigorously developed in carbon materials. Its appearance is a silver gray, porous solid with metallic luster, and its structure has obvious flowing texture. The pores are large but few and slightly elliptical, and the particles have a large aspect ratio, similar to fibrous or needle like texture. It has a lubricating feel and is a raw material for producing high-end carbon products such as ultra-high power electrodes, special carbon materials, carbon fibers and composite materials. Needle coke is a scarce product both domestically and internationally. In addition to being used in electrodes, it can also be used in potassium ion batteries and electrochemical capacitors. Nuclear graphite and other aspects have been applied.
