摘要： A method and apparatus for using fixed abrasive polishing pads that contain posts for chemical mechanical polishing (CMP). The posts have different shapes, different sizes, different heights, different materials, different distribution of abrasive particles and different process chemicals. This invention also includes preconditioning fixed abrasive articles comprising a plurality of posts so that the posts have equal heights above the backing to achieve a uniform texture. This invention relates to improvements with respect to in situ rate measurement (ISRM) devices. The invention resides in providing a mechanical means, such as a notch, to determine when approaching the end of the abrasive web roll. The invention resides in coding the web throughout its length to enable determining the location of different portions of the web. This invention resides in providing perforations in the sides or end of the web for improved handling.

摘要： Disclosed are a mixture of a stone polishing pad, a stone polishing pad made of the mixture and a method for manufacturing the stone polishing pad. Instead of planar structure, the stone polishing pad has polishing protrusions and an uneven surface formed on the surface of the polishing protrusions that contacts with the polished object. The stone polishing pad is formed by charging a mould with the mixture of the stone polishing pad that includes cork powder, and forming the same under high temperature and high pressure.

摘要： A superabrasive tool such as a superabrasive grindstone (101; 102), a superabrasive dresser (103; 104; 105) or a superabrasive lap surface plate (106) includes a base (20) of steel and a superabrasive layer (10) formed on the base (20). The superabrasive layer (10) includes superabrasive grains (11) consisting of diamond grains, cubic boron nitride grains or the like and a holding layer consisting of a nickel plating layer (16) and a bond layer (17), or a brazing filler metal layer (18), holding the superabrasive grains (11) and fixing the same onto the base (20). Grooves (12) or holes (14) are formed on flat surfaces (19) of the superabrasive grains (11) exposed from the holding layer (16, 17; 18). The holding layer (16, 17; 18) holding and fixing the superabrasive grains (11) so that the surfaces of the grains are partially exposed is formed on the base (20). The grooves (12) or the holes (14) are formed by irradiating the surfaces of the superabrasive grains (11) exposed from the holding layer (16, 17; 18) with a laser beam (50). Working of high accuracy can be performed by forming the grooves (12) or the holes (14) on the surfaces of the superabrasive grains (11).

摘要： Microcrystalline boehmite suitable for conversion to anhydrous alumina products is produced by hydrothermal treatment of precursor alumina raw material at controlled pH and in the presence of microcrystalline boehmite seed material. Reaction mix may include submicron seed material for seedling for later conversion of the microcrystalline boehmite to alpha alumina. Removal of metal cations by ion exchange is employed when high purity product is required. Other materials may be added to reaction mix. Production of alumina products, catalysts, and ceramic bodies is disclosed.
