Tech Licensing Opportunity: Synthesis of Tungsten Tetraboride (WB4) by Electric Field Assisted Sintering (EFAS) BA-1537
Summary
AI-generated · Sep 17, 2025A licensing opportunity is offered for the production of tungsten tetraboride (WB4) using Electric Field Assisted Sintering (EFAS). EFAS provides controlled sintering without melting, which helps achieve WB4 with minimal impurities and hardness near the theoretical maximum, and it enables scalable production such as larger batches and discs up to 12 inches. The technology is at TRL 3 and is associated with a US provisional patent application; INL notes that licensing terms are customized for each partner and focuses on commercializing the technology.
INL Technology Deployment invites interested companies to pursue licensed rights to commercialize this WB4 EFAS method. The licensing approach is flexible and tailored to the business, with no government purchase or funding commitment implied. This is a technology licensing opportunity, not a procurement or external development service, and discussions are handled through INL’s technology partnership program.
Synthesis of Tungsten Tetraboride (WB4) by Electric Field Assisted Sintering (EFAS) A novel method for synthesizing tungsten tetraboride (WB4), a material with exceptional hardness and thermal properties, using Electric Field Assisted Sintering (EFAS). The Challenge: In the pursuit of materials with exceptional hardness and thermal conductivity, tungsten tetraboride (WB4) has been considered a compelling candidate since the 1960s. Renowned for its potential in enhancing cutting tools, armor, and nuclear reactors, WB4's synthesis has been limited by technological constraints, yielding products often inferior to their theoretical capabilities. Enter Electric Field Assisted Sintering (EFAS) a modern technique set to revolutionize WB4 production by maintaining precise conditions necessary for optimal material characteristics. How it Works: Electric Field Assisted Sintering (EFAS) introduces a sophisticated approach to WB4 synthesis, surpassing traditional methods like arc melting which often resulted in impurities and unwanted phases such as WB2. Unlike previous techniques, EFAS employs controlled sintering temperatures and accurate atomic ratios without the need to melt the components, thereby preserving the desired WB4 phase and preventing degradation in material hardness. This process has been demonstrated to produce WB4 samples with hardness approaching theoritical maximum by controlling the granular composition and phase outcomes efficiently. Key Advantages: Enhanced Material Quality: By avoiding the melting process, EFAS ensures the production of WB4 with minimal impurities and maximum hardness. Scalability: The method is scalable, capable of producing larger batches and custom sizes (up to 12" discs), which was previously unachievable. Cost-Effectiveness: Utilizes less expensive raw materials and optimizes the synthesis process, reducing overall production costs. Radiation Resistance: Uniquely suitable for nuclear applications due to its neutron absorption capabilities and resistance to high-temperature degradation. Problems Solved Inconsistent synthesis quality and low yield of WB4 using traditional methods High cost and complexity of large-scale production of materials with similar properties Lack of cost-effective and efficient materials for extreme thermal environments and radiation shielding Market Applications Industrial Machining: Enhance the longevity and performance of machining tools used in automotive and aerospace manufacturing. Defense and Ballistic Protection: Imagine lighter, more effective armor that provides enhanced protection against various threats. Nuclear Safety: Boost the safety and efficiency of nuclear reactors, contributing to sustainable and safer energy solutions. Development Status: TRL 3 US Provisional Patent Application No. 63/643,127, METHODS OF FORMING REFRACTORY METAL BORIDES BY ELECTRIC FIELD ASSISTED SINTERING (EFAS), BEA Docket No. BA-1537 INL Tech Partnerships: Your Gateway to Innovation INL offers strategic access to proprietary technology, enhancing small business growth and contributing to economic and public advancement.
