- Description
- Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to commercialize its partial sintering method to create larger-sized powder particles from smaller ones in order to ensure suitability and conformance to intended application. Background: During powder processing, a fraction of the production will inevitably be powder particles that are smaller than the desired size range.� Typically, these particles are remelted, and the recycled material is processed into powder again.� The series of extra steps (i.e., pressing, remelting) that are subsequent to the original powder making process, requires additional time and significant energy costs, especially the remelting of the material.� LLNL researchers have developed an alternate method to increase powder size without �starting over� by melting the powder particles again.� The less costly solution involves sintering, a process in which powders are heat treated at an elevated temperature that is below their melting point.� During sintering, solid diffusion is promoted in the material, and subsequently, adjacent particles fuse together where they contact each another, rendering particles of greater size than before sintering.� Description: LLNL has developed a process to partially sinter starting material composed of smaller-sized powder particles to obtain a loose powder product that have larger-sized particles.� �To avoid the undesired formation of a single fully-sintered piece, the starting powder material is heated for a relatively shorter time.� The time and temperature required for partial sintering is dependent on the powder material properties, powder size, temperature, and desired size distribution.� If the particle size of the partially sintered powder is larger than the desired size range, it could be subsequently milled or otherwise ground to obtain the desired particle size.� Advantages/Benefits: Value Proposition:� Reduced powder waste leads to lowering of manufacturing and operating costs. Ability to produce powder not just of desired size, but of other properties uniquely required for a specific application, e.g., can also be a method to produce powder with unique porous properties. Potential Applications: Powder recycling and reprocessing Production of special powders of desired size and properties Development Status:� Current stage of technology development:� TRL 3 LLNL has filed for patent protection on this invention. LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information.� Please visit the IPO website at https://ipo.llnl.gov/resources for more information on working with LLNL and the industrial partnering and technology transfer process. Note:� THIS IS NOT A PROCUREMENT.� Companies interested in commercializing LLNL's partial sintering to creater larger powder particles �should provide an electronic OR written statement of interest, which includes the following: Company Name and address. The name, address, and telephone number of a point of contact. A description of corporate expertise and/or facilities relevant to commercializing this technology. Please provide a complete electronic OR written statement to ensure consideration of your interest in LLNL's partial sintering method. The subject heading in an email response should include the Notice ID and/or the title of LLNL�s Technology/Business Opportunity and directed to the Primary and Secondary Point of Contacts listed below. Written responses should be directed to: Lawrence Livermore National Laboratory Innovation and Partnerships Office P.O. Box 808, L-779 Livermore, CA� 94551-0808 Attention:�� IL-13680
