Technical ceramics manufacturer CoorsTek has purchased BAE Systems' Vista, CA, advanced ceramics facilities. These three facilities total 106,000 ft²—adding to the more than 3 million ft² of manufacturing floor space already in place worldwide. The Vista, CA, ceramics business was acquired by BAE Systems through its acquisition of United Defense Inc. in June 2005. These facilities develop and fabricate lightweight ceramic armor systems, semiconductor components and assemblies, and industrial components. Specifically, they manufacture hot-pressed boron carbides, silicon carbides, aluminum nitrides, and other advanced ceramic materials.
