The boron-modified molybdenum silicide material is fabricated into such products as electrical components, such as resistors and interconnects, that exhibit oxidation resistance to withstand high temperatures in service in air as a result of electrical power dissipation, electrical resistance heating elements that can withstand high temperatures in service in air and other oxygen-bearing atmospheres and can span greater distances than MoSi.sub.Type: GrantFiled: August 19, 1996Date of Patent: February 2, 1999Assignee: Iowa State University Research Foundation, Inc.Inventors: Mitchell K.

Patent number: 5779823Abstract: A titanium silicide material based on Ti.sub.5 Si.sub.3 intermetallic compound exhibits substantially improved oxidative stability at elevated temperatures. In particular, carbon is added to a Ti.sub.5 Si.sub.3 base material in an amount (e.g. about 0.3 to about 3.6 weight % C) effective to impart substantially improved oxidative stability at elevated temperatures, such as about 1000.degree. C. Boron is added to a Ti.sub.5 Si.sub.3 base material in an amount (e.g. about 0.3 to about 3.3 weight % B) to this same end.Type: GrantFiled: August 15, 1996Date of Patent: July 14, 1998Assignee: Iowa State University Research Foundation, Inc.Inventors: Andrew J. Thom, Mufit Akinc
