Advanced Materials Manufacturing with Cryogenic Milling and Spark Plasma Sintering (SPS) at California Nanotechnologies

California Nanotechnologies specializes in advanced materials manufacturing by leveraging cryogenic milling and Spark Plasma Sintering (SPS) to engineer high-performance materials for cutting-edge applications. By integrating these advanced processing techniques, we achieve unparalleled control over microstructure, phase stability, and mechanical properties—pushing the limits of material performance across aerospace, energy, defense, and green technology industries.

This presentation will highlight our recent advancements in refractory high-entropy alloys (RHEAs), where cryogenic milling enables ultra-fine microstructures that enhance high-temperature strength and oxidation resistance. Additionally, we will discuss our work in advanced ceramics, including ultra-hard materials, transparent ceramics, and high-temperature composites, where SPS provides rapid densification while preserving nanoscale features. Our expertise also extends to diffusion bonding applications and the production of high-performance alloys for nuclear and hypersonic applications.

Beyond technical advancements, this talk will explore the scalability and sustainability of these processes. Compared to conventional methods, cryogenic milling and SPS offer enhanced material efficiency, reduced energy consumption, and minimal waste, making them ideal for sustainable manufacturing. We will also discuss how California Nanotechnologies is bridging the gap between R&D and commercial production, enabling large-scale adoption of these novel materials.

Through case studies and industry collaborations, we will showcase how our advanced manufacturing capabilities are driving innovation in next-generation materials. As industries demand lighter, stronger, and more resilient materials, California Nanotechnologies remains at the forefront, developing tailored solutions to meet these evolving challenges.
