Abstract

The invention relates to a zircon mullite saggar, belonging to the field of refractory materials, and being used for effectively preventing acid corrosion and alkali corrosion of a lithium solution on a saggar body. For solving the technical problem, the invention adopts the technical scheme that the zircon mullite saggar comprises the following components in percentage by weight: 68-79% of Al2O3, 0.65-18.5% of SiO2, 10-12.7% of ZrO2, 0.2-0.5% of Fe2O3, 0.05-0.1% of CaO and 0.1-0.2% of MgO.

Description

technical field [0001] The invention relates to a zircon mullite sagger, which belongs to the field of refractory materials. Background technique [0002] Lithium usually needs to be melted into liquid lithium, purified, and cooled in a mold to form lithium rods. Lithium can react with oxygen to generate lithium oxide, and lithium can also react with water to generate lithium hydroxide. Therefore, the sagger for melting lithium must be resistant to acid and alkali. The existing saggers are bonded by corundum bricks, and the composition and weight percentage of the corundum bricks are Ai 2 o 3 95%, ZrO 2 4.5%, Fe 2 o 3 0.3%, SiO 2 0.2%. However, the corundum brick-bonded sagger cannot resist the acidic and alkaline corrosion of lithium solution well, so the service life is short. Contents of the invention [0003] The problem to be solved by the present invention is to provide a zirconium-mullite sagger, which can effectively prevent the lithium solution from acidic...
