Method for preparing magnesia-stabilized zirconia crucible through casting molding
The invention discloses a method for preparing a magnesia-stabilized zirconia crucible through casting molding, and relates to the technical field of refractory materials. The preparation method comprises the steps that: in commercial magnesia-stabilized zirconia powder (MgO 3.5%, ZrO2 96.5%), a binding agent, deionized water and a dispersing agent with a certain ratio are added, such that a slurry with good fluidity is obtained, wherein a weight ratio of the above materials is 100:(5-15):(15-30):(0.5-5). Mixing is carried out in a drum, such that a slurry is obtained; the slurry is added into a plaster mold; the plaster mold is placed in air with an inclined position; demolding is carried out after 0.5-1.5h, and a blank is fetched; a final firing temperature is 1600-1700 DEG C, and the temperature is maintained for 3-10h; and a cooling speed is controlled, such that the magnesia-stabilized zirconia crucible is obtained. The method has the advantages of simple process equipment and uniform crucible wall thickness. The prepared magnesia-stabilized zirconia crucible has relatively high strength, relatively high refractoriness, high density, good thermal stability, good erosion resistance, and cracking resistance during a sintering process.
