According to Wikipedia, superhard material is a material with a hardness exceeding 40GPa. In the field of abrasives industry, diamond and cBN are widely used currently. Diamond includes Natural Diamond and Synthetic Diamond, while cBN can only be synthetic. Synthetic diamond is the hardest material in manufacturing industry and has been widely used in metallurgy, oil drilling, construction and machinery industry. As for the question of whether PCD and cBN belong to materials or products, iAbrasive.com (http://www.iabrasive.com) puts them in the category of material.
As shown in Figure 1, Superhard Materials include 8 sub-categories.
I. Natural Diamond
Natural Diamond, as a kind of natural abrasives, is very rare in nature. Same as abrasive grains, it also has Grading System and related Available Size.
Grading System: ANSI, FEPA, JIS, ISO, GB/T, Other
Available Size: Customized
Applications: Resin Bonded Abrasives, Metal Bonded Abrasives, Vitrified Abrasives, Electroplated Products, Lapping/ Polishing, Sawing Tools, Drilling/ Milling Tools, Dressing Tools, Wire Drawing Dies, Other

II. Synthetic Diamond
Synthetic Diamond is the widely used material in the field of Superhard Material. In iAbrasive.com, Synthetic Diamond is not divided by Category but Attribute.
Type: Mesh, Micron, Coated & Clad, Metal Encapsulated
Particle Shape: Blocky, Angular, Sharp, Irregular, Other
Grading System: same as Natural Diamond
Available Size: Customized
Color: Light Brown, Brown, Black, Aqua, Green, Dark Green, Light Yellow, Yellow, Gray, Colorless, Other
Metal Coated: None, Copper, Nickel, Silver, Titanium, Combo, Other
Application: PCD/ PDC, the rest is same as that of Natural Diamond

III. Cubic Boron Nitride
With the similar crystal structure of Diamond and the hardness less than that of Diamond, cBN is usually used as abrasive grains and cutting tools. Until now, there is no natural cBN to be found in nature. As for the category & attribute of cBN, iAbrasive.com refers to that of Synthetic Diamond. Type, Particle Shape, Grading System, Available Size, Metal Coated and Applications are same as that of Diamond. But Color is different from that of Diamond.
Color: Amber, Dark Amber, Black, Brown, Other

IV. PCD/ TCP
PCD/ TCP is the Poly Crystal Diamond sintered under high temperature by putting diamond and bonding agent together, with high heat resistance and high heat stability. It is wide used in oil manufacturing, drilling, diamond manufacturing and machinery manufacturing, etc.
Type: PCD, TSP
Shape: Cube, Cylinder, Disc, Rectangle, Triangle, Spheres, Hexagon, Other
Application: Gem Processing, Drilling Bits, Other

V. PCBN
PCBN is sintered under high temperature by putting cBN and bonding agent together.
Shape: Cube, Cylinder, Disc, Rhombus, Triangle, Hexagon, Other

VI. CVD Diamond
CVD can be used to produce a synthetic diamond by creating the circumstances necessary for carbon atoms in a gas to settle on a substrate in crystalline form.
Shape: Triangle, Square, Round, Bar, Other

VII. Nano Diamond
In iAbrasive.com, there has not been proper category and attribute for Nano Diamond, but it will be added when the posted products are rich.

VIII. Other
In iAbrasive.com, it is not recommended to put the posted products in “Other” category, unless you are sure that you are not able to find the proper category for your products in above 7 categories. The reason is that the products in the category of “Other” will be put at the end of the product list in iAbrasive.com.

Warm Notice:
iAbrasive.com strongly believes that you’d better not put your product into the category of “Other”, unless you indeed can not find the proper classification. In iAbrasive.com, the products in the category of “Other” will be show in the button of product listing. Also, iAbrasive.com will make adjustment for current categories & attributes irregularly for this category. For example, add some new or hide some current ones, etc. You are warm welcome to share your opinions with us if you have different views about the Category & Attribute explained here. We will read your feedbacks carefully. Thanks a lot. Email: s@iabrasive.com
