US-Germany Cooperative Research: Corrosion of Silicate Glass Ceramics by Oxide Melts and Impacts on Glass Recycling

0340733 Misture该奖项支持Scott Misture、Christopher辛顿和阿尔弗雷德大学的一名学生与德国克劳斯塔尔技术大学非金属材料研究所的Joachim Deubener和Lothar Wondraczek合作。 合作的总体目标是促进两所大学的玻璃科学和陶瓷工程项目之间的新的专业联系，并获得描述玻璃陶瓷和氧化物玻璃熔体之间相互作用的初步数据，这对支持改善工业玻璃回收至关重要。 研究小组将进行一系列实验，收集初步数据，并建立与氧化物玻璃熔体直接接触的硅酸盐玻璃陶瓷腐蚀模型。 这些数据将用于创建模型，以描述两种材料之间的腐蚀机制。 该项目的成果将在两个方面具有重要意义：玻璃回收，其中玻璃陶瓷的溶解是有利的;相反，对于先进熔化技术的坩埚和搅拌器等应用，材料的耐用性至关重要。 在玻璃回收中，陶瓷和玻璃陶瓷污染是一个持续存在的问题，可能导致玻璃中的缺陷，有时会损坏熔炉、孔板和成形设备。 在德国，玻璃纤维生产中使用的碎玻璃中的玻璃陶瓷污染问题非常严重，以至于该行业正在考虑停止使用回收材料。 对于先进的玻璃熔化，玻璃陶瓷材料具有用作关键的长寿命熔化和成形工具的潜力。 两个PI团队和两个机构拥有互补的专业知识和设施，将确保富有成效的互动

0340733MistureThis award supports Scott Misture, Christopher Sinton, and a student from Alfred University in a collaboration with Joachim Deubener and Lothar Wondraczek of the Institute for Non-metallic Materials at the Technical University of Clausthal, Germany. The overall goals of the collaboration are to foster new professional links between the glass science and ceramic engineering programs at the two universities, and to obtain preliminary data describing the interactions between glass-ceramics and oxide glass melts that is critical to support improved industrial glass recycling. The research team will undertake a set of experiments to gather preliminary data and establish models of the corrosion of silicate glass ceramics in direct contact with melts of oxide glasses. The data will be used to create models to describe the corrosion mechanism between the two materials. The outcome of the project will be significant from two perspectives: glass recycling, where the dissolution of the glass-ceramic is favorable; and, conversely, for applications such as crucibles and stirrers for advanced melting techniques where the durability of the materials is critical. In glass recycling, ceramic and glass-ceramic contamination is a continuing problem that can lead to flaws in the glass and sometimes damage the furnace, orifices, and forming equipment. In Germany, the problem of glass-ceramic contamination in cullet used in fiberglass manufacture is so great that the industry is considering discontinuing the use of recycled material. For advanced glass melting, glass-ceramic materials have the potential to be used as critical long-life melting and forming tools. The two PI teams and the two institutions have complementary expertise and facilities that will ensure a fruitful interaction
