Transparent Ain Ceramics

Available in large sizes up to 18x35.

Transparent ain ceramics. High optical transmission 85 near uv to mid ir wavelengths 0 25 to 4 0 μm crystal clear. 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 0µm when combined with selected materials source. Excellent refractive index homogeneity over large areas commercially available. Many ceramic materials both glassy and crystalline have found use as optically transparent materials in various forms from bulk solid state components to high surface area forms such as thin films coatings and fibers.

Alon optical ceramic s key features. Outstanding hardness scratch resistance and high strength high quality.

Optical fibers for guided lightwave transmission optical switches. Aluminum nitride aln is a unique ceramic material that combines high thermal conductivity with high electrical resistivity. Monocrystalline transparent ceramics are ideally suitable for applications that require high optical transparency and mechanical strength. Naval research laboratory citation needed.

What has happened however and in fact what was happening in research circles at least as far back as 1981 is the development of a transparent aluminum based ceramic called aluminum oxynitride aka alon that sounds a heckuva. Transparent polycrystalline ceramics have found various applications such as laser hosts infrared ir windows domes lamp envelopes and transparent armors instead of their single crystal counterparts due mainly to their processing flexibility in fabricating items with large sizes and complex shapes and more importantly cost effectiveness. Excellent clarity and no inherent birefringence durable. Beryllium oxide beo and cubic boron nitride c bn are virtually the only other examples.

Monocrystalline transparent ceramics is the largest and the fastest growing segment of the transparent ceramics market in 2016. This review summarizes the status of the development of these ceramics and a case study on. Many ceramic materials both glassy and crystalline have found use as optically. The transparent ceramic systems which are explored currently include transparent alumina as polycrystalline submicron alumina and single crystal sapphire al 2 o 3 aluminium oxynitride alon spinel mgal 2 o 4 and zinc sulphide zns ceramics.

Only a few ceramics possess high thermal conductivity.
