Abstract: High-performance inorganic artificial stone is a new type of artificial stone developed in recent years. The paper systematically introduces the concept, performance, classification, forming and curing methods of high-performance inorganic artificial stone, focusing on the analysis of high-performance inorganic artificial stone’s modification, as well as research and application status and development trends. The following conclusions are drawn: Compared with ordinary inorganic artificial stone, high-performance inorganic artificial stone has better mechanical and decorative properties; additives and polymers can reduce the water absorption rate of the board and increase the flexural strength of the board; fiber modified materials can significantly improve the toughness of the inorganic artificial stone plate, but the appearance of the plate will be affected when the add amount of fiber modified materials is large. With the improvement of the quality and performance of inorganic artificial stone products, inorganic artificial stone will gradually occupy part of market which belongs to the resin artificial stone and natural stone before and become the mainstream product in building decoration materials.
