A method for lapping a material comprising the steps of:
- providing a material;
- providing a holder;
- providing a lapping plate;
- providing an abrasive slurry comprising abrasive particles wherein the average surface roughness of said particles is less than about 0.95;
- affixing said material within said holder;
- placing said material against said lapping plate on either one or both sides of said material;
- rotating said lapping plate;
- rotating said holder and said material against said lapping plate;
- and
- applying said abrasive slurry to said lapping plate, wherein said slurry abrades said material until a desirable material thickness or surface finish is achieved.
