| titleOfInvention | Zirconium dioxide short fiber and magnesium oxysulfate whisker composite reinforced magnesium oxide-based crucible and preparation method thereof |
| abstract | The invention discloses a preparation method of a zirconium dioxide short fiber and basic magnesium sulfate whisker composite reinforced magnesium oxide-based crucible, which can realize sintering at low temperature and has excellent chemical stability and thermal shock resistance, and the method comprises the following steps: (1) preparing 15-25% of nano alumina sol, 0.8-1.5% of rheological agent and the balance of electric melting magnesia ceramic powder containing nano lanthanum oxide, zirconium dioxide short fiber and basic magnesium sulfate whisker according to the mass percentage, adding deionized water, performing ball milling and mixing uniformly, and then performing vacuum exhaust to prepare ceramic slurry with the solid content of 70-80%; (2) preparing a crucible biscuit; (3) putting the dried biscuit into a sintering furnace, sintering at high temperature, and cooling along with the furnace to obtain a magnesium oxide-based crucible blank; (4) and (3) carrying out vacuum infiltration treatment on the magnesium oxide base crucible blank in alumina sol, then carrying out surface polishing treatment, drying, carrying out high-temperature secondary sintering, and cooling to room temperature along with a furnace to obtain the magnesium oxide base crucible. |
