Aluminum Carbide Ceramics
Aluminum silicon carbide is a metal ceramic composite material consisting of silicon carbide particles dispersed in a matrix of aluminum alloy.
Aluminum carbide ceramics. Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Learn about product property coefficient of thermal expansion. Ceramic materials ordered by hardness. Kyocera is the global leading manufacturer of superior precision fine ceramics advanced ceramics.
Aluminas aluminum oxide al 2 o 3 are the most commonly used technical ceramics due to their generally useful properties and good price performance ratio alumina ceramics are commonly subdivided according to their alumina content ranging from 80 to more than 99. The non oxide ceramic silicon carbide sisic or ssic is a ceramic material that is as hard as diamond and features many other important characteristics. Ceramic materials ordered by density. The behavior of high alumina refractories in the presence of carbon is explained.
With its composite features al sic is an advanced packaging material for high technology thermal management. Because of the high reactivity of aluminum carbide and all the intermediate compounds with moisture and oxygen use of refractories based on the system a1 2 o 3 a1 4 c 3 must be limited to applications where these agents are excluded. Alsic pronounced alsick is a metal matrix composite consisting of aluminium matrix with silicon carbide particles. It has high thermal conductivity 180 200 w m k and its thermal expansion can be adjusted to match other materials e g.

Once fired and sintered it can only be machined using diamond grinding methods. The properties of many of the ceramics are shown below for reference. The lightest and hardest ceramic material ceramtec offers is available as ssic sintered silicon carbide and sisic silicon infiltrated silicon carbide.
Silicon carbide sic also known as carborundum k ɑːr b ə ˈ r ʌ n d əm is a semiconductor containing silicon and carbon it occurs in nature as the extremely rare mineral moissanite synthetic sic powder has been mass produced since 1893 for use as an abrasive grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications.
