Abstract: With the development of industrial technology, casting processes are constantly advancing. The high-temperature environment in the casting process requires more stringent requirements for casting materials. This article mainly explores the high-temperature resistance performance of casting bentonite and analyzes its influencing factors. Through comparative experiments with different kinds and different processing methods of bentonite, it was found that its high-temperature resistance performance is related to its composition, structure, and surface treatment. In addition, the stability and thermal shock resistance of bentonite under high temperature were discussed, as well as how to improve its application effect through optimizing formula and process. Finally, the research results were summarized, and the prospects of bentonite's application in the field of casting were also prospected.
