The Department of Energy, through the Battelle Energy Alliance–DOE CNTR, is offering a technology licensing opportunity for a novel method of synthesizing tungsten tetraboride (WB4) using Electric Field Assisted Sintering (EFAS). Identified by solicitation number BA-1537 and currently at Technology Readiness Level (TRL) 3, this method addresses historical production challenges by utilizing controlled sintering temperatures and accurate atomic ratios without melting components. This process preserves the desired WB4 phase and minimizes impurities to produce materials with hardness approaching theoretical maximums and enhanced thermal conductivity. The technology is applicable to industrial machining, ballistic protection, and nuclear applications due to its radiation resistance and neutron absorption capabilities.
This special notice is classified under NAICS 333248 All Other Industrial Machinery Manufacturing and PSC 9630 ADDITIVE METAL MATERIALS. The synthesis technique is scalable, allowing for the production of custom sizes up to 12-inch discs, and is designed to be more cost-effective than traditional arc melting methods. The intellectual property is associated with US Provisional Patent Application No. 63/643,127, titled "METHODS OF FORMING REFRACTORY METAL BORIDES BY ELECTRIC FIELD ASSISTED SINTERING (EFAS)."
Licensing for this technology is managed by Idaho National Laboratory (INL) Tech Partnerships in Idaho Falls, ID. The agency seeks industry collaborators capable of commercializing the innovation and will negotiate licensing terms tailored to individual business needs. Responses to this notice are accepted through May 1, 2026. Andrew Rankin is the designated point of contact for this opportunity, which does not involve purchasing, procurement decisions, or external development funding.
