CeraNova’s proprietary process for transparent spinel enables net-shape forming and densification at lower temperature without sintering aids. The resulting fine grained (< 10µm) microstructure demonstrates high transmission (visible through MWIR) and mechanical strength (>300MPa) two to three times higher than conventional large grain transparent spinel. CeraNova prototype windows (275mm square) show high transmission and low scatter. Processing of larger flat panels and curved shapes with significant sag is underway. Defense applications include large reconnaissance windows for aircraft and ships, smaller flat and curved windows for IR and laser countermeasure systems, and transparent armor. CeraNova specializes in process and product development of innovative, high technology ceramic materials. Application partners and commercialization opportunities are sought as the company transitions from technology development to prototype and pilot-scale manufacturing.
Transparent nanocrystalline alumina (CeraLumina™) matches the high in-line transmission of sapphire in the MWIR, and has isotropic behavior and enhanced mechanical properties. CeraNova’s net-shape forming process enables deep concave and conformal shapes not possible or practical with single crystal sapphire, and reduces processing time and cost. The company specializes in advanced materials and products for demanding applications, and has unique capabilities not only to form ogive domes and conformal windows, but also to grind and polish them to high optical precision. Prototype optical quality hemispheric and ogive domes have been produced for future missile platforms or for substitution of sapphire in existing platforms, e.g. AIM9X. Conformal sensor windows (e.g., for UAV’s) are being developed for future ISR platforms. Partners are sought for application-specific dome/window testing.
