Calcium oxide crucible and preparation method thereof
The invention discloses a calcium oxide crucible and a preparation method thereof, and belongs to the technical field of refractory materials, the method comprises the following steps: adding an organic monomer, a cross-linking agent and a dispersing agent into an organic solvent, and mixing to form a premixed solution; a calcium oxide mixture, a sintering aid and carbon fibers are added into the premixed liquid to be mixed, a catalyst and an initiator are added under continuous stirring, slurry is formed after uniform stirring, the calcium oxide mixture comprises 60-80% by weight of particles and 20-40% by weight of powder, the weight of the calcium oxide mixture accounts for 60-80% of that of the slurry, and the weight of the powder accounts for 20-40% of that of the particles. The weight of the carbon fibers accounts for 0.05-0.2% of the weight of the slurry; injecting the slurry into a crucible mold under a vibration condition, and forming a wet blank after a monomer polymerization reaction; and the wet blank is subjected to demolding drying, degumming pre-sintering and high-temperature sintering treatment in sequence, and the calcium oxide crucible is obtained. The technical effect of prolonging the service life of the crucible is achieved.
