- Abstract
Currently, a large amount of chromium-containing solid waste (CCSW) is still accumulating, and has caused a series of ecological problems that are difficult to solve. Inorganic materials have been extensively studied for their capability to consume CCSW. This paper reviews the research on four groups of inorganic materials: glass ceramics, sintering ceramics, cement, and geopolymers. Furthermore, their properties, chromium solidification ability, and mechanism are summarized. Based on these experimental data and theories, future research in the field will likely focus on the following aspects: (1) establishing a systematic database of inorganic materials used to treat CCSW, comprehensively considering their chromium solidification ability and maximum waste consumption; (2) saving energy, simplifying the processes, and generating products with high added value; and (3) investigating the long-term chromium-leaching behavior of inorganic materials in different environments in order to improve the safety evaluation of materials prepared from CCSW.
