Ceramic Laser Materials
Laser host materials
Polycrystalline ceramics such as yttrium-aluminum-garnet (YAG) provide many advantages over single-crystal, including reduced fabrication times, component design flexibility, ease of manufacture, and lower cost. CeraNova has developed extrusion technology to manufacture YAG fibers for use in high-energy lasers.
High-energy laser windows
The optical, thermal, and mechanical properties of CeraNova’s transparent magnesium aluminate spinel make it an excellent material for exit window apertures with high-energy lasers.
Laser-based igniter systems will enable cleaner burning, higher efficiency, and more economical combustion engines. CeraNova’s fine grain polycrystalline ceramics are potential candidates as host, light guide, or window components in such systems.
Scintillator materials are used for radiation detection in medical diagnostics, industrial inspection, and high-energy physics. CeraNova’s fine grain polycrystalline ceramics have been evaluated for possible use in radiation detection systems. The fine grain structure produced through CeraNova’s proprietary processes may offer significant performance advantages in terms of transparency, resolution, x-ray stopping power, and light output.
CeraNova’s fine grain ceramic materials are compatible with a variety of conductive coatings, including transparent oxides of tin, indium, and zinc as well as metals such as gold, silver, and titanium nitride. Transparent conductors are used in a range of applications requiring, for example, low emissivity, RF shielding, or touch sensitivity.
Recent developments in thermoelectric oxides are showing promise for this class of materials as thermoelectric converters. Oxides have potential advantages over other types of thermoelectric materials due to their chemical and thermal stability at high temperatures. CeraNova’s expertise in the processing and product development of fine grain oxide ceramics will be applicable to a number of the challenges faced in commercializing these materials.
CeraNova’s high density alumina product, CeraLumina™, has ultra-low porosity and impurity content, fine and uniform grain size, and a highly dense and smooth surface, which give it excellent dielectric breakdown performance. These attributes combined with CeraNova’s low-cost near-net shape manufacturing methods open up a number of possible application areas for CeraLumina as a high performance insulator.
