Transparent ceramics. Transparent spinel (MgAl 2 O 4) ceramic is used traditionally for applications such as high-energy laser windows because of its excellent transmission in visible wavelengths and mid-wavelength infrared (0.2–5.0 μm) when combined with selected materials – source: U.S. Naval Research Laboratory [citation needed] Many ...
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%) in the near-ultraviolet, visible, and mid-wave- infrared regions of the electromagnetic spectrum. It is four times as hard as fused silica ...
Transparency and translucency. Dichroic filters are created using optically transparent materials. In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable scattering of light. On a macroscopic scale (one in which the dimensions are ...
Yttralox is a transparent ceramic consisting of yttria (Y 2 O 3) containing approximately 10% thorium dioxide (ThO 2 ). [1] [2] It was one of the first transparent ceramics produced, [3] and was invented in 1966 by Richard C. Anderson at the General Electric Research Laboratory while sintering mixtures of rare earth minerals .
It can be made nearly transparent (15–20% loss in a typical cooktop) for radiation in the infrared wavelengths. In the visible range glass-ceramics can be transparent, translucent or opaque and even colored by coloring agents. However, glass-ceramic is not totally unbreakable.
Soldiers pictured during the 2003 Iraq War seen through IR transparent Night Vision Goggles. The military requirements of World War II encouraged developments, which created a need for high-performance materials and helped speed the development of ceramic science and engineering. Throughout the 1960s and 1970s, new types of ceramics were ...
Transparent conducting films (TCFs) are thin films of optically transparent and electrically conductive material. They are an important component in a number of electronic devices including liquid-crystal displays, OLEDs, touchscreens and photovoltaics. [1][2] While indium tin oxide (ITO) is the most widely used, alternatives include wider ...
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. While offering superior electrical properties, high ...
