California Nanotechnologies Corp. engages in the research, development, and production of nano-structured components and materials. The company is headquartered in Cerritos, California. The company went IPO on 2004-12-06. The firm's two core technologies are Spark Plasma Sintering (SPS) and Cryogenic Milling. SPS is an advanced sintering & bonding technique for all varieties of materials, including metallic alloys, high-temp ceramics, high entropy alloys, and everything in between. The company provides powder consolidation and material bonding toll services via its multiple Spark Plasma Sintering Systems for everything from fundamental R&D to production. Cryogenic Milling is a cutting-edge powder processing technique used for particle size reduction (to nano scale), mechanical alloying and nano-grain refinement. This process is high-energy attrition ball milling at cryogenic temperatures, which provides benefits to traditional milling/mixing technology. The firm provides toll services for R&D and production needs and has multiple milling systems on-site.
