Abstract: Disclosed is a method of chem-mech polishing an electronic component substrate. The method includes the following steps;obtaining a substrate having at least two features thereon or therein which have a different etch rate with respect to a particular etchant; andcontacting the substrate with a polishing pad while contacting the substrate with a slurry containing the etchant wherein the slurry includes abrasive particles, a transition metal chelated salt and a solvent for the salt.The chem-mech polishing causes the at least two features to be substantially coplanar. Also disclosed is the chem-mech polishing slurry.

Abstract: A method of preparing abrasive articles exhibiting improved homogeneity and breakdown properties is disclosed. The method comprises admixing abrasive grits and a bond phase comprising silica particles, alumina, a flux and water, to form a slurry, such that the silica particles are on the average smaller than the average grit particles; drying the slurry to form a precursor powder; and compacting the precursor powder to form an abrasive greenware article. This abrasive greenware article can then be densified, for example, by sintering, to form a densified abrasive article. The resulting abrasive article has a porcelain bond composition. Because of the uniform bond composition attained with this invention, extremely fine abrasive grits can be employed.

Abstract: The invention provides a method of producing an abrasive particle, particularly diamond, containing strip. The strip will contain 50 percent or less by volume of the diamond particles and a supporting matrix which will generally be metal. The method involves making a mixture of the abrasive particles and the supporting matrix in particulate form, causing a thin layer of the mixture to be deposited on to a support surface, compacting the layer and heat treating the compacted layer under conditions which will not lead to degradation of the abrasive particles to produce the strip.

Abstract: A process for improving the grinding performance of a porous ceramic or plastic bound grinding or honing body, using the steps of obtaining a conventionally produced porous ceramic or plastic bound grinding or honing body, and filling the pore spaces of the body at least in part with at least one metal soap.

Abstract: A fabric softening heavy duty liquid detergent composition of controlled viscosity, which does not thicken excessively on aging, includes certain proportions of sodium linear higher alkylbenzene sulfonate, sodium alkyl polyethoxy sulfate, builder salt (highly preferably a mixture of sodium tripolyphosphate and sodium carbonate), finely divided swelling bentonite, low molecular weight polyacrylate and water. Such product is a stable pourable liquid of desired viscosity, density and pH, convenient for use in washing machines, for hand washing of laundry and for pre-treatment of badly soiled portions of items to be laundered. The presence of a small percentage of the polyacrylate in the composition prevents the viscosity thereof from increasing on storage to such an extent as would interfere with pourability.

Abstract: Monoglycosides have been found to increase the viscosity of aqueous-based detergent compositions containing anionic surfactants.

Abstract: A grinding wheel is described which is bonded with a phenol formaldehyde resin based bond containing hexamethylenetetramine as the curing agent. The wheels are made by first wetting the abrasive with furfural in varying quantities relative to the amount of hexamethylenetetramine in the phenol formaldehyde resin. Different amounts of the curing agent require different specific amounts of furfural to produce optimum properties in the finished grinding wheel.
