The article deals with the laboratory preparation of clinker mineral belite. It monitors the stability of β-C2S with respect to the firing regime and the effect of the stabilizing additive H3BO3. Belite was prepared by high-speed milling using solid-state reaction at 1150, 1250, 1350 and 1450 °C with 30 min soaking. It deals in more detail with the higher temperature 1450 °C where it compares the content of individual phases of belite with samples prepared without the stabilizer H3BO3. The results showed a significant stabilizing effect of boron at a higher firing temperature. The effect of the stabilizer is more pronounced in firing regimes, where γ-C2S is more readily formed, especially at firing temperature 1450 °C with 0, 30, 60 and 90 min soaking. In the samples with the stabilizing additive, double the amount of β-C2S was identified in comparison with the β-C2S was prepared using a stabilizer H3BO3.
