A production method of zirconium disilicide, the raw materials zirconia powder, silicon dioxide powder and graphite powder are added to industrial binder and ball milled in a vacuum ball mill to obtain a mixed material; the mixed material is pressed into a circular cake-shaped block by an oil press , put it into a vacuum sintering furnace, evacuate to 1Pa, send electricity and heat up once for sintering to obtain coarse zirconium disilicide, finish crushing, ball milling, powder making, add industrial binder, put it into a hydraulic press abrasive tool, and stamp it. Obtain crude zirconium disilicide block material, put it into the quartz crucible of the vacuum induction melting furnace, send electricity to raise the temperature for secondary melting, after being fully melted, pour it into the crucible and take it out of the furnace to cool; pink. The advantages are: reasonable process, strong operability, through strict control of reaction conditions, first vacuum sintering, then vacuum smelting, two-stage silicon-zirconium alloying reaction, so that the alloying degree of zirconium disilicide can reach 100%, and the synthesis temperature is relatively low Low, suitable for industrial production.
Description
A kind of production method of zirconium disilicide technical field The present invention relates to a kind of production method of zirconium disilicide. Background technique Zirconium is a kind of "rare metal", its melting point is high, and has the characteristics such as ultra-high corrosion resistance, hardness and strength, Zirconium and zirconium alloys are widely used in aerospace, military industry, nuclear reaction, atomic energy and other fields as well as general industrial production. two Zirconium silicide has excellent corrosion resistance and excellent mechanical properties, so it can be used in high temperature corrosive media. Structural materials and new engineering materials, in addition, it can also be used as a special steel additive to improve the toughness, strength and Wear resistance, improve the hardenability, weldability and machining corrosion properties of steel. However, zirconium disilicide is due to its high production cost and labor...
