Copper magnesium

Fluorine can be handled using a variety of materials (100—103). Table 4 shows the corrosion rates of some of these as a function of temperature. System cleanliness and passivation ate critical to success. Materials such as nickel, Monel, aluminum, magnesium, copper, brass, stainless steel, and carbon steel ate commonly used. Mote information is available in the Hterature (20,104). 

The use of salts such as magnesium, copper sulphate or calcium chloride in the vicinity of the ground grid may improve the conductivity of the soil. 

Dicyclohexylammonium nitrite s (DCHN) has a solubility of 3-9g in 100 g of aqueous solution at 25°C, giving a solution pH of about 6-8. Its vapour pressure at 25°C appears to be about 1-3 x 10 N/m but the value for commercial materials depends markedly on purity. It may attack lead, magnesium, copper and their alloys and may discolour some dyes and plastics. Cyclohexylammonium cyclohexyl carbamate (the reaction product of cyclohexylamine and carbon dioxide, usually described as cyclo-hexylamine carbonate or CHC)" is much more volatile than DCHN (vapour pressure 53 N/m at 25°C), and much more soluble in water (55 g in 100cm of solution at 25°C, giving a pH of 10-2). It may attack magnesium, copper, and their alloys, discolour plastics, and attack nitrocellulose and cork. It is said to protect cast iron better than DCHN, and to protect rather better in the presence of moderate concentrations of aggressive salts. 

Modification of the burning rates, pressure exponents, and temp coefficients of burning rate of the fluorocarbon composites has been accomplished with copper, lead, tin, sodium, ammonium and potassium fluoborates sodium, potassium, lithium, lead, copper and calcium fluorides potassium and ammonium dichromate lead and zinc stearate cesium carbonate potassium and ammonium sulfate copper chromite oxides of magnesium, copper and manganese boron zinc dust and carbon black (Ref 75)... 

Duralumin (alloy of aluminium, magnesium, copper and manganese) used for structural purposes, e.g. in aircraft construction. 

On the anodic side chlorine is formed, which reacts with all anode materials known so far. At first we used mercury later on several research teams used aluminum, magnesium, copper, etc., [20]. All these are sacrificial anodes and the corresponding chlorides were formed. Graphite shows rapid passivation. Silicon with a small copper content for better conductivity reacts with the removal of the copper, and the conductivity decreases.

In 1834, A. J. Balard prepd solutions of various hypochlorites by mixing aq hypochlorous acid with alkalies, magnesium, copper oxide, zinc oxide etc, avoiding an excess of acid J. L. Gay-Lussac dissolved two mols of chlorine monoxide, C120, in a solution containing 1 mol of K20 and then evaporated the resulting solution in vacuo. This gave solid potassium hypochlorite...

Metals and ceramics (claylike materials) are also used as matrices in advanced composites. In most cases, metal matrix composites consist of aluminum, magnesium, copper, or titanium alloys of these metals or intermetallic compounds, such as TiAl and NiAl. The reinforcement is usually a ceramic material such as boron carbide (B4C), silicon carbide (SiC), aluminum oxide (A1203), aluminum nitride (AlN), or boron nitride (BN). Metals have also been used as reinforcements in metal matrices. For example, the physical characteristics of some types of steel have been improved by the addition of aluminum fibers. The reinforcement is usually added in the form of particles, whiskers, plates, or fibers. 

Attempts were made to extend the r,(7-transfer of allyl ligand from palladium to other, metals (fdf) (magnesium, copper, zinc, cadmium, and liquid gallium). It has been found that these metals do not form their respective allyl derivatives in reaction with rr-allyl-palladium chloride. 

Silicon and its compounds are used to add strength to alloys of aluminum, magnesium, copper, and other metals.
