Silicon steam corrosion resistant coating and preparation method thereof
The invention discloses a silicon steam corrosion resistant coating and a preparation method thereof. The coating is prepared from the following components in percentage by mass: 15-35% of hexagonal boron nitride, 1-10% of ethanol, 1-10% of glycerol and 50-80% of a diluent, wherein the total percentage of the components is 100%. The coating can be utilized for protecting a graphite crucible under the atmosphere of high-temperature silicon steam at 1700 DEG C or higher, so that the surface of the graphite crucible can be protected to a great extent, and the corrosion caused by the silicon steam is reduced; the coating can further be utilized for the surfaces of a heat preservation barrel, a heater and other main graphite toolings in addition to the crucible; moreover, the coating has the characteristics of being simple in technical process, low in cost, suitable for popularization and application, high in high-temperature property and harmless to a human body.
