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.
Future weapon systems require sensor windows that can survive severe mechanical and thermal stresses while providing the optical performance necessary for target recognition. CeraNova’s proprietary process produces spinel with high in-line transmission (>80% from 200nm to 5000nm) and strength 2-3 times higher than other spinels. CeraNova spinel can provide the improved optical/mechanical/thermal performance required for demanding applications, i.e., sensor windows, missile domes and transparent armor. CeraNova specializes in high technology ceramics process and product development, especially transparent optical ceramics for defense and commercial applications. Large spinel conformal windows (16”x16”) and plates (20”x20”) are being developed; transparent 4”x4” tiles have been produced for ballistic testing (Q3/Q4 2018). We seek application and transition partners for relevant environment testing and evaluation leading to prototype and pilot scale manufacturing.
