Method for prolonging service life of graphite crucible in siliconized graphite prepared through vacuum gas phase deposition reaction method
The invention discloses a method for prolonging the service life of a graphite crucible in siliconized graphite prepared through a vacuum gas phase deposition reaction method. The method comprises the following steps: 1) preparing the siliconized graphite by using the graphite crucible, respectively and uniformly coating a siliconized reaction raw material on the inner surface of the graphite crucible and the surface of a graphite substrate, and filling an anti-sticking agent between the graphite crucible and the graphite substrate; 2) placing the graphite crucible placed with the graphite substrate into a vacuum furnace, preparing the graphite substrate into the siliconized graphite through the vacuum gas phase deposition reaction method, and uniformly forming a siliconized graphite layer on the inner surface of the graphite crucible; and 3) reusing the graphite crucible, and filling the anti-sticking agent between the graphite crucible and the graphite substrate. According to the method provided by the invention, the number of use of the graphite crucible exceeds 10 times, therefore the service life of the graphite crucible can be prolonged, and the production cost can be saved.
