Aluminum black dross is produced by the secondary smelting process of aluminum. Aluminum black dross is classified as hazardous waste because it is reactive with water and produces substances and gases that are harmful to humans and the environment. Generally, aluminum black dross is managed by landfill method, but because it is produced in large amounts every year, the aluminum black dross needs to be utilized to reduce the impact on the environment. Aluminum black dross consists of large amounts of metal oxide and salts. The amount of metal oxide content in aluminum black dross can be used as raw material. This paper review types of processes for utilizing black dross aluminum as raw material in value-added products. aluminum black dross can be used as alumina, adsorbent, zeolite, composites, geopolymers, refractories, and fillers. By utilizing aluminum black dross waste into various products that have economic value, besides being able to protect the environment, it can also reduce environmental resource use.

“…The 3D four‐directional brained structure significantly improves the interlayer mechanical properties of the composites and also retains the characteristics of excellent in‐plane mechanical properties, which has become the main preform structure of C/SiC composite nozzles for aerospace vehicles. [ 23–29 ] C/SiC composites are mainly processed by polymer infiltration and pyrolysis (PIP), hot press sintering, reactive melt infiltration, and chemical vapor infiltration (CVI). [ 30–37 ] Among them, the PIP process has three significant advantages.…”

The specific effects on the evolution of microstructure, components and mechanical properties of the three‐dimensional braided C/SiC composites under different‐time electron irradiation environment tests were analyzed and discussed to elaborate the corresponding corrosion damage mechanism. The damage to the C/SiC composites was intensified by the continuous electron irradiation, the areas of surface bulges and cracks were significantly enlarged, and the surface roughness increased. The density of white dots on the surface of the specimen increased as the electron irradiation time was prolonged, while the size did not change significantly, and the oxygen content on the surface of the specimen increased to some extent. With the prolongation of electron irradiation time, the decrease of bending strength of C/SiC composites increased, but did not level off after a certain degree, probably because of the existence of certain pores on the surface layer of the C/SiC composite. With the increase of electron radiation time, the crack defects on the surface layer of the C/SiC composite increased, and the electron radiation further damaged the internal matrix and reinforcing fibers in the C/SiC composite, thus the mechanical properties declined continuously and seriously after the radiation exceeded 1 h.This article is protected by copyright.
