The inoculants like calcium silicide, ferrosilicon, aluminum silicon and silicon carbide have been used in the present investigation. The effect of these inoculants on the micro and macro properties of grey cast iron have been investigated. The results reveal that the
Silicon carbide shows particular promise as a high temperature structural material (ref. 1). In gas turbine, chemical reactor, and heat exchanger appliions, this material may be exposed to molten salts. Evidence has been accumulating which indies that SiC
The corrosion resistance of 11 nickel-based compositions to molten sodium hydroxide at 1500 degrees and 1700 degrees was studied in order to find a container material for the caustic at these temperatures. Although, in caustic, pure nickel is corrosion resistant
Silicon Carbide thermocouple tubes have the wide oxidization resistance and corrosion resistance. It can be widely used in thermometric system of molten metals. FEATURES: Cost effective No Coating Required Long life typically >2-3 months No melt
Silicon carbide bricks are a kind of refractory brick used high purity silicon carbide(SIC) and industrial silicon powder as the primary materials. Silicon carbide bricks have the advantages of wear resistance, good erosion resistance, high strength, excellent thermal conductivity and thermal shock resistance, good oxidation resistance, low porosity and better adhesion resistance,etc.
In order to determine extent of problem for ceramic materials, corrosion of SiC by molten salts studied in both jet fuel burners and laboratory furnaces. Surface of silicon carbide corroded by exposure to flame seeded with 4 parts per million of sodium.
Soluble in molten sodium hydroxide, potassium hydroxide and in molten iron. Appliions Silicon carbide is used in abrasives, in polishing and grinding. It is widely applied in appliions calling for high endurance, such as automobile brakes, car clutches and
