“…It is well known that Mg 27 enhances the wetting of SiC by molten aluminum. Previous studies have shown that the addition of a reactive metal, that is, Mg, to the liquid drop accelerates the interaction with the substrate 28,29 . It has been shown that magnesium additions to aluminum lower molten drop surface tension 30 and its work of immersion in SiC 31 .…”

“…Previous studies have shown that the addition of a reactive metal, that is, Mg, to the liquid drop accelerates the interaction with the substrate. 28,29 It has been shown that magnesium additions to aluminum lower molten drop surface tension 30 and its work of immersion in SiC. 31 Consequently, aluminum alloys that are specifically designed for infiltration of SiC beds have invariably contained varying amounts of Mg. Another investigation indicated that one of the main functions of Mg as a surfactant element is to reduce any aluminum oxide that may be present in the interface.…”

The reactive wetting behavior in molten aluminum and Al alloy was investigated by the sessile drop method for three alumina‐silicon carbide composites, namely TC, TQ, and MC. The initial contact angle for all the three refractory substrates was obtuse in spite of a gradual decrease with time in the first hour of the experiment. TC showed a higher contact angle than TQ and MC. The difference in wetting properties among these refractories is attributed to their compositional and microstructural variations. The effects of magnesium in the molten Al alloy on the wetting kinetics and the reaction with the refractory substrates are also discussed.

“…In 2021, China's new energy industry chain led the world, providing more than 70% of the global market's photovoltaic modules 75 . China is already the world's largest auto manufacturing and consumer market and has gained obvious technological and industrial advantages in new energy transportation 76 . Among the industries that contribute to achieving carbon neutrality, the new energy vehicle industry chain has the strongest certainty and the greatest commercialization prospect 77 .…”

As the global climate crisis intensifies, ecosystems, human society and economic activities are significantly affected. Countries around the world have successively put forward the goal of carbon neutrality or zero carbon. At the 75th session of the United Nations General Assembly, the Chinese government explicitly proposed making efforts to reach the goal of Carbon Peak (peak of carbon emissions before 2030) and Carbon Neutrality (Dual Carbon) (carbon neutrality before 2060). In October 2021, the CPC Central Committee and the State Council issued the “Opinions on Fully, Accurately and Comprehensively Implementing the New Development Concepts to Achieve Carbon Peak and Carbon Neutrality” and the Action Plan for Achieving Carbon Peak before 2030, specifying the targets and tasks related to achieving carbon peak and carbon neutrality in China. As the world's largest developing country, the world's largest manufacturer, and a country with the most complete industrial categories, China will face multiple challenges such as climate change, economic transition, and environmental protection, which requires systematic support from policy, economy, technology, and society. How to achieve the goal will be a great challenge to China's sustainable development. The academic community has conducted extensive exploration on the realization of China's carbon peak and carbon neutrality in many fields, such as energy transformation, industrial structure upgrading, transportation carbon reduction, urban planning and construction, carbon sink enhancement, low‐carbon technologies, green finance, and supporting policies. Among them, policy planning and technological innovation are the most important to achieve the goal of carbon peak and carbon neutrality. Second, industrial adjustment and enterprise implementation are also important. Therefore, this review will focus on the development status and prospects of policy support, technological innovation, industrial adjustment, and enterprise implementation for achieving dual carbon goals in China. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.
