The Influence of Boron Doping on the Structures and Composition of Dicalcium Silicate: A Research Study

This paper investigates the structural transformation of dicalcium silicate (C2S) crystals brought about through boron doping. Both qualitative and quantitative analyses were conducted to explore the correspondence between boron content and the structure of dicalcium silicate. The results show that boron doping can stabilize beta-C2S and the high-temperature phase alpha ' H-C2S, and the structural transformation does not involve the modulation of alpha ' L-C2S. There is a corresponding relationship between the unit cells of beta-C2S and alpha ' H-C2S, which can be transformed using a transformation matrix. The relationship between boron content and the content of different C2S structures, as well as the structural expressions for beta-C2S and alpha ' H-C2S, is determined using linear fitting and multivariable linear regression analysis.
