摘要： This invention provides a method for increasing the cutting performance of a wire saw, in cutting a substrate, by increasing the association of the abrasive particles in the cutting slurry and the cutting wire, the enhancement being caused by the use of thickening agents in the cutting slurry or by increasing the attraction of the abrasive particles to the cutting wire.

摘要： A wiresaw cutting fluid composition of the present invention comprises about 25 to about 75% by weight of a particulate abrasive suspended in an aqueous carrier containing a polymeric viscosity modifier that comprises a polymer including a majority of non-ionic monomer units (preferably 100 mol % non-ionic monomer units), has a number average molecular weight (Mn) of at least about 5 kDa, and is present in the composition at a concentration sufficient to provide a Brookfield viscosity for the composition in the range of about 50 to about 1000 cP, e.g., 50 to about 700 cP, at about 25° C. at a spindle rotation rate of about 60 rpm. In one embodiment, the viscosity modifier comprises a polymer having a weight average molecular weight (Mw) of at least about 200 kDa. When a viscosity modifier of 200 kDa or greater Mw is utilized, a preferred wiresaw cutting method the cutting fluid is circulated and applied by pumps and nozzles operating at a relatively low shear rate of not more than about 104 s−1.

摘要： The present invention provides chemical-mechanical polishing (CMP) compositions suitable for polishing a substrate comprising a germanium-antimony-tellurium (GST) alloy. The CMP compositions of the present invention are aqueous slurries comprising a particulate abrasive, a water-soluble surface active agent, a complexing agent, and a corrosion inhibitor. The ionic character of the surface active material (e.g., cationic, anionic, or nonionic) is selected based on the zeta potential of the particulate abrasive. A CMP method for polishing a GST alloy-containing substrate utilizing the composition is also disclosed.

摘要： Provided is a manufacturing method of ferromolybdenum from molybdenite concentrate, and more particularly, a manufacturing method of ferromolybdenum with copper content of 0.5% or less from molybdenite with high copper content without carrying out a separate copper removing process by putting molybdenite, aluminum metal and iron metal, in a heating furnace and reacting them at high temperature to manufacture the ferro molybdenum at the lower portion thereof, forming a slag using aluminum sulfide and iron sulfide as the main components at the upper portion thereof, and putting most of the copper (80 to 95%) existing in the molybdenite in a slag layer. The exemplary embodiment can shorten a process as compared to a metallothermic reduction (Thermit) method of the related art and reduce the consumption of a reducing agent, i.e., aluminum.
