Application: Coated (CORE-SHELL) nanoparticles for nanocomposite optical ceramics (Patent ID: US20240199497A1)
The patent filed by Raytheon Technologies Corp. describes a nanocomposite optical ceramic (NCOC) material consisting of coated nanoparticles with a first material core and a second material shell. The materials are mutually insoluble, have high transmissivity, low difference in index of refraction, and small grain sizes. The coating is thin, and the NCOC has minimal voids. The NCOC is designed to limit grain growth when exposed to high temperatures.
The patent also outlines a method for producing these coated nanoparticles, involving coating uncoated nanoparticles with a second material, followed by dry pressing, compacting, sintering, and hot isostatic pressing to form the NCOC material. The method ensures the NCOC contains minimal voids and limits grain growth at high temperatures. Different combinations of materials are specified for the core and shell, such as magnesium oxide and yttrium oxide, gallium arsenide and silicon, aluminum oxide and zirconium oxide, aluminum nitride and silicon, and calcium lanthanum sulfide and zinc sulfide. The method also includes mixing coated nanoparticles with uncoated nanoparticles and compacting them to form the final NCOC material.
