Abstract

Disk shaped fine carbon particles. A fine carbon particle having a diameter of less than 3 microns and a height of less than 0.05 micron substantially in disk form are described. Admixtures with other fine particles are also described.

What is claimed is: 
     
         1 . A fine carbon particle having a diameter of less than  3  microns and a height of less than 0.05 micron, substantially in disk form. 
     
     
         2 . The particle of  claim 1  wherein the disk includes a circumference and a diameter, and wherein the circumference is 95% to 105% of 3.1415 times the diameter. 
     
     
         3 . An admixture of fine carbon particles including the disks of  claim 3  present in an amount of at least 1% by weight. 
     
     
         4 . The admixture of  claim 3 , wherein the disks are present in an amount of at least 10% by weight. 
     
     
         5 . The particle of  claim 1  wherein the diameter/height aspect ratio is at least 4. 
     
     
         6 . The particle of  claim 5  wherein the aspect ratio is at least 10 but less than 200. 
     
     
         7 . The particle of  claim 5  wherein the aspect ratio is between 4 and 150. 
     
     
         8 . The particle of  claim 1  made by two distinct injection regions of carbonaceous feedstock. 
     
     
         9 . The particle of  claim 1  made by a gas phase process using natural gas. 
     
     
         10 . An admixture of spherical and/or ellipsoidal fine carbon particles including at least 1% by weight of the particles of  claim 1 .
