Carbon-graphites offer the design engineer a unique family of mechanical materials. Manufactured entirely from carbon and including high temperature carbonaceous bonding, these materials combine the strength, hardness and wear resistance of carbon with the corrosion resistance and self lubricating properties of graphite. The precisely controlled inherent porosity of carbon-graphites can ...

Abstract
On the rear panel in Plasma Display Panel, barrier ribs were formed in stripe and matrix arrangements to maintain the discharge space between the two glass plates as well as to prevent electrical and optical cross talking between the adjacent cells. Various barrier rib forming routes were proposed including screen ...

The nickel-chromium system shows that chromium is quite soluble in nickel. This is a maximum at 47% at the eutectic temperature and drops off to about 30% at room temperature. A range of commercial alloys is based on this solid solution. Such alloys have excellent resistance to high temperature oxidation ...

Nickel oxide has a range of applications such as:
· For making electrical ceramics such as thermistors and varistors e.g. ferrites (nickel zinc ferrite)
· Pigments for ceramic, glasses and glazes
· Nickel oxide can be reacted with acids to form salts and other compounds e.g. nickel sulfamate for electroplating and nickel molybdate ...

Basic aluminum sulfate can be prepared by homogeneous precipitation starting from admixtures of ammonium aluminum sulfate and ammonium bisulfite solutions. Powder agglomeration problems usually arise in wet precipitation processes mainly at high concentration of precursors. Some organic additives have been used in order to modify the physical and chemical properties ...
