Sintered high-zirconium brick and preparation method thereof
The invention relates to a sintered high-zirconium brick and a preparation method thereof, and the sintered high-zirconium brick used at the liquid level line position of a glass melting tank is prepared from the following raw materials in percentage by weight: 76-88 wt% of ZrO2; 5 to 10 wt% of a ZA eutectic; 2 to 8 wt% of Y2O3; 2 to 6 wt% of MgO; 2 to 4 weight percent of CaO; 0.4 to 1.2 weight percent of CeO2; and 0.3 to 1 wt% of SrO. According to the sintered high-zirconium brick disclosed by the invention, the glass-erosion-resistant main component zirconium dioxide is introduced, and the product is sintered at high temperature for a long time, so that crystal development is good. According to the sintered high-zirconium brick disclosed by the invention, the corundum baddeleyite plate-shaped eutectic is introduced into the system ingredients, and the eutectic belongs to a plate-shaped structure and has the performance of buffering thermal stress, so that the sintered high-zirconium brick has excellent thermal shock resistance, and the sintered high-zirconium brick disclosed by the invention has excellent glass erosion resistance and ideal service life; the method is of great significance in improving the product quality, reducing the cost and improving the social benefit of a glass enterprise.
本发明涉及以一种烧结高锆砖及其制备方法，所述用于玻璃熔化池液面线位置的烧结高锆砖包括以下重量百分比的原料制成，ZrO2 76‑88wt％；ZA共晶体5‑10wt％；Y2O3 2‑8wt％；MgO 2‑6wt％；CaO 2‑4wt％；CeO2 0.4‑1.2wt％；SrO0.3‑1wt％。本发明的烧结高锆砖由于引入抗玻璃侵蚀的主组分二氧化锆，由于制品长时间高温烧结，使得晶体发育良好。本发明的烧结高锆砖由于体系配料中引入了刚玉斜锆石板状共晶体，这种共晶体属于板状结构，具有缓冲热应力的性能，使得制品具有优良的抗热震性能，本发明的烧结高锆砖具有优良的抗玻璃侵蚀性能和理想的使用寿命，对于玻璃企业提高产品质量、降低成本、提高企业和社会效益具有重要意义。
