Abstract

The invention relates to a magnesium zirconium brick, and belongs to the field of fireproof materials. A cooker built by magnesium zirconium bricks is capable of effectively preventing acidic corrosion and alkali corrosion of liquid-state lithium. According to the technical scheme, the magnesium zirconium brick comprises the following components by weight percent: 90%-95% of MgO, 4.5%-7.1% of ZrO2, 0.3%-1.7% of TiO2 and 0.2%-1.2% of SiO2.

Description

technical field [0001] The invention relates to a magnesia-zirconium brick, 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 furnace for melting lithium must be resistant to acid and alkali. The existing stoves are made of 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 furnace made of corundum bricks cannot resist the acidic and alkaline corrosion of liquid lithium 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 magnesia-zirconium brick. The furnace made of magnesia-zirconium brick can effectively...
