合成SiC通常需要>1000C

这个只要600C
该文的一作好像在海归某高校了

Shi, Y., Zhang, F., Hu, Y. S., Sun, X., Zhang, Y., Lee, H. I., ... & Stucky, G. D. (2010). Low-temperature pseudomorphic transformation of ordered hierarchical macro-mesoporous SiO2/C nanocomposite to SiC via magnesiothermic reduction. Journal of the American Chemical Society, 132(16), 5552-5553.

A magnesiothermic reduction synthesis approach is reported for direct conversion of SiO2/C composite nanostructures to corresponding SiC materials without losing their nanostructure morphologies. Crystalline SiC materials can be obtained by this approach at a temperature as low as 600 °C, only approximately half of that applied in the generally used carbothermal reduction and preceramic polymer pyrolysis methods. An ordered hierarchical macro-mesoporous SiC material was synthesized for the first time as a demonstration. This pseudomorphic transformation can be regarded as a general synthesis method for different kinds of SiC nanostructures, and it can also be readily extended to other metal carbide materials as well as TiC.
