摘要:
Gel-free colloidal abrasive polishing compositions and associated methods for polishing (e.g., chemical mechanical polishing) are described. These abrasive polishing compositions are comprised of a surface-modified colloidal abrasive that has been modified with a boron-containing compound(s), such as boron surface-modified colloidal ceria or silica. These compositions are useful in chemical mechanical planarization (CMP) applications as well as in substrate polishing applications. These abrasive compositions are most often negatively-charged colloids, which remain as stable negatively-charged colloids even in acidic media.
摘要:
A process is provided to prepare solid borozirconate and solid borotitanate cross-linkers, which comprises contacting zirconium or titanium complex with alkanolamine at particular mole ratios of boron, zirconium or titanium and alkanolamine. Use of the cross-linkers in compositions for oil field applications such as hydraulic fracturing and plugging of permeable zones are also disclosed.
