A superabrasive material and method of making the superabrasive material are provided. The superabrasive material may comprise a superabrasive crystal having an irregular surface. The superabrasive material further comprises a plurality of structure defects within the superabrasive crystal. The plurality of structure defects may cause micro-chipping when used as grinding materials.

A sintered polycrystalline diamond material (PCD) of extremely fine grain size is manufactured by sintering under high pressure/high temperature (HP/HT) processing, a diamond powder which is blended with a pre-milled source catalyst metal compound. The PCD material has an average sintered diamond grain structure of less than about 1.0 &#x3bc;m.

A method of producing a coated paper having reduced gloss mottle and excellent smoothness includes the steps of calendering a base stock at a relatively high pressure in a first calendering step, coating at least one side of the calendered base stock and calendering the coated base stock at a relatively low pressure in a second calendering step.
