Patent number: 6919036Abstract: A family of borate compounds containing an isolated (finite) nonaborate anion with the structural formula [B9O12(OH)6]3?. Preferred amine nonaborate compounds have a resolved oxide formula of A2O.3B2O3.2H2O, where A is the monovalent cation of an amine salt, such as guanidinium and imidazolium. Also provided is a method for preparing these compounds by crystallization from an aqueous solution under mild conditions without the formation of significant amounts of by-products. These compounds have potential application as precursors for the production of advanced boron nitride ceramic materials, and as flame retardants, corrosion inhibitors, and biocides.Type: GrantFiled: January 18, 2001Date of Patent: July 19, 2005Assignee: U.S. Borax Inc.Inventor: David M.

Patent number: 6556642Abstract: The present invention relates to a method for inhibiting stress corrosion cracking occurring on steam generator tubes in the secondary side of nuclear power plants and an inhibitor therefor. The method comprises supplying cerium boride as an inhibitor for stress corrosion cracking into the secondary feed water of the nuclear power plants. The method according to the present invention improves resistance of stress corrosion cracking three times or higher than no inhibitor, and two times or higher than the conventional inhibitor. In particular, the method according to the present invention shows a superior inhibiting effect in the lead-contaminated environment such that the complete inhibition of stress corrosion cracking can be achieved. As thus, the method can reduce the unexpected stop of operating nuclear power plants caused by the stress corrosion cracking on steam generator tubes, thereby reducing the cost required for maintaining and repairing the tubes.Type: GrantFiled: October 23, 2001Date of Patent: April 29, 2003Assignees: Korea Atomic Energy Research Institute, Korea Electric Power CorporationInventors: Do Haeng Hur, Joung Soo Kim
