摘要:
A refractory object can include a beta alumina. In an embodiment, the refractory object is capable of being used in a glass fusion process. In another embodiment, the refractory object can have a total Al2O3 content of at least 10 % by weight. Additionally, a Mg-Al oxide may not form along a surface of the refractory object when the surface is exposed to a molten glass including an Al-Si-Mg oxide. In a particular embodiment, a refractory object can be in the form of a glass overflow forming block used to form a glass object that includes an Al-Si-Mg oxide. When forming the glass object, the glass material contacts the beta alumina, and during the flowing of the glass material, a Mg-Al oxide does not form along the beta alumina at the surface.
摘要(中):
耐火物体可以包括β氧化铝。 在一个实施例中,耐火物体能够用于玻璃熔融工艺。 在另一个实施方案中,耐火物体可以具有至少10重量%的总Al2O3含量。 此外,当表面暴露于包含Al-Si-Mg氧化物的熔融玻璃时,Mg-Al氧化物可不沿着耐火物体的表面形成。 在特定实施例中,耐火物体可以是用于形成包括Al-Si-Mg氧化物的玻璃物体的玻璃溢流形成块的形式。 当形成玻璃物体时,玻璃材料与β-氧化铝接触,并且在玻璃材料流动过程中,在表面上没有沿β氧化铝形成Mg-Al氧化物。
