AbstractOptical quality polycrystalline spinel (MgAl2O4) has been sought as a visible and infrared-transmitting material since the 1960s. Applications for its potential usage include transparent armor and durable sensor windows and domes. Though gains have been made in the optical quality of transparent spinel materials, the Navy"s requirements in the near future are not meet by current spinel materials principally due to low strength. This program builds on CeraNova"s Phase I success in developing fine grain, highly transparent, high strength (greater than 400MPa) spinel. The material was developed with a more economical, scalable process than currently used to produce windows as large as 40cm by 40cm or larger.
