attention. Coarse grinding is a critical stage, so, if the soft graphite is lost during coarse grinding, it cannot be recovered in subsequent steps and will be seen as an open or collapsed cavity. Sil-icon carbide SiC grinding papers are preferred to emery, because SiC cuts efciently, while em-ery paper does not, and SiC produces less dam-age.

The Durrans Group has over 50 years experience in selecting, processing and distributing Amorphous Graphite to the Foundry, Refractory and Chemical and industries. Amorphous is the least graphitic of the natural graphites. The term amorphous is a misnomer since this material is in fact truly crystalline.
Graphite Statistics and Information. Graphite is a soft, crystalline form of carbon. Other forms are diamond and fullerenes buckyballs . It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic. Graphite occurs naturally in metamorphic rocks such as marble, schist, and gneiss.
While manufacturing Natural Graphite Flakes we use the advanced and unique milling technology, which helps in grinding the Natural Graphite Flakes to ultra-fine powder. We can control the particle size distribution and carbon content. The fixed carbon is from 90 to 99.9, and the particle size is adjustable, from 2 micron to 18 micron at D50.
3. The method of claim 1 for dry grinding a workpiece, wherein the graphite is flake graphite. 4. The method of claim 3 for dry grinding a workpiece wherein the graphite is present in an amount of from about 10 to 30 by wt. based on the MgO content of the bond, and is
