At the International Symposium on Refractories 2025 to be held on September 17-18, 2025, the global refractory industry's attention will be focused on Aachen, Germany. Our company participated in the exhibition with our core product, tabular alumina, and supporting technical solutions. With outstanding product strength, we shone brightly at this international event and became one of the focuses.
At the exhibition, our company's key display of tabular alumina attracted many foreign merchants to stop and engage in in-depth negotiations with its four outstanding advantages. This product uses the "high-temperature melting crystallization" process to accurately control the melting temperature of 1900 ℃, and adopts a slow cooling rate to promote the formation of a complete sheet-like crystal structure. Compared to traditional fused alumina, its apparent porosity has decreased to below 3%. Even in extreme high temperature environments of 1700 ℃, excellent structural stability can still be maintained, which can help downstream enterprises extend the service life of kiln lining by 2-3 times, greatly reducing maintenance frequency and lowering production costs. Through a special impurity removal process, the product strictly controls the content of harmful impurities such as Fe2O3 and Na2O below 0.1%, effectively avoiding the adverse effects of impurity volatilization on product performance at high temperatures. It perfectly meets the extremely strict requirements for refractory material purity in high-end manufacturing fields such as precision ceramics and photovoltaic glass. A technical representative from a precision ceramic company in Germany praised on site, saying, "Its stability effectively solves the core concern of long-term stable operation of our high-end kilns.
The technical team provided detailed answers to customers' questions about material selection and construction splicing under high temperature conditions at the exhibition site. This exhibition not only showcases our company's technological innovation in the field of refractory materials with low-carbon product solutions, but also echoes the global trend of industrial green transformation, injecting new momentum into promoting low-carbon development in the industry and international green cooperation. Further expanding the channels of Zibo HUAO in the international market has laid a solid foundation for future overseas cooperation.
