Transparent alumina ceramics. Katarina drdlikova karel maca martin slama daniel drdlik transparent alumina ceramics. Alon is optically transparent 80 in the near ultraviolet visible and midwave infrared regions of the electromagnetic spectrum. Effect of standard and plasma generated stabilizing approaches in colloidal processing. 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.

Alon or aluminum oxynitride is an amazing and unique transparent advanced ceramic that is polycrystalline made from powder with a cubic spinel crystal structure. Transparent alumina al 2 o 3 ceramic wafers are frequently applied in industry however it is usually difficult to obtain a high quality transparent alumina ceramic wafer without any deformation here we present a nonaqueous tape casting method which is followed by a presureless vacuum sintering process to fabricate the transparent alumina ceramic wafers with restrained or eliminated. In the popular media and in the star trek community it is commonly referred to as transparent aluminum. Surmet is the only company globally that manufactures alon.

The scene as written seems to imply that scotty is talking about some fancy way of making metallic aluminum into a transparent form. Transparent alumina ceramics were fabricated using an extrusion based 3d printer and post processing steps including debinding vacuum sintering and polishing. It is four times harder than fused silica glass 85 as hard as sapphire and nearly 15 harder than magnesium. Transparent alumina is currently one of the most mature transparent ceramics from a production and application perspective and is available from several manufacturers.

To determine the influence of the atmosphere on grain growth a. But the cost is high due to the processing temperature involved as well as machining costs to cut parts out of single crystal boules. Translucent and transparent ceramics have a higher thermal resistance than glass or resin and they are stronger and harder. Aluminium oxynitride or alon is a ceramic composed of aluminium oxygen and nitrogen it is marketed under the name alon by surmet corporation.
