Transparent ceramics have recently acquired a high degree of interest and notoriety. Basic applications include lasers and cutting tools, transparent armor windows, night vision devices (NVD), and nose cones for heat seeking missiles. Currently available infrared (IR) transparent materials typically exhibit a trade-off between optical ...
Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.
Lumicera is a transparent ceramic developed by Murata Manufacturing Co., Ltd.. Murata Manufacturing first developed transparent polycrystalline ceramics in February 2001. This polycrystalline ceramic is a type of dielectric resonator material commonly used in microwaves and millimeter waves.
Invisible braces are a type of transparent ceramics called translucent polycrystalline alumina (TPA). A company known as Ceradyne developed TPA in conjunction with NASA Advanced Ceramics Research as protection for infrared antennae on heat-seeking missile trackers. [13]
With the intention of manufacturing technical ceramics, they reorganized their cooperation in 1971. The result was the company Rosenthal Stemag Technische Keramik GmbH, which was renamed Rosenthal Technik AG in 1974. In 1985 Hoechst AG acquired the company and from that point on operated it under the name Hoechst CeramTec AG.
Large laser elements made from transparent ceramics can be produced at a relatively low cost. These components are free of internal stress or intrinsic birefringence, and allow relatively large doping levels or optimized custom-designed doping profiles. This makes ceramic laser elements particularly important for high-energy lasers.

The company's product, View Dynamic Glass, features an electrochromic (EC) coating composed of multiple layers of ceramic metal oxide with a thickness of 1 micron. [18] Low voltage wiring is added so the tint of the glass can be controlled through an app or centralized software system in response to weather or interior temperature.
