TiO2 was employed to develop cordierite glass–ceramics for thermal transmission pipeline binders by a melt‐quenching method. The effects of TiO2 on the phase composition, microstructure, and physical properties of glass–ceramics were studied. In addition, the thermal shock resistance of the glass–ceramics based binder was investigated. The results showed the formation of α cordierite could be increased by adding 1.0 wt% TiO2, thereby improving bending strength and decreasing the coefficient of thermal expansion. However, a 3‐5 wt% TiO2 additive resulted in massive generation of µ cordierite, which exhibited a negative effect on the above performances. After crystallization at 1000°C for 2 h, sample B1 (1 wt% TiO2 additional) displayed the best overall properties. It was demonstrated that cordierite glass–ceramics were satisfactory materials as heat transmission pipeline binders when the C2 binder (40 wt% frit, 60 wt% as‐prepared sample B1) was applied, which had a good thermal shock resistance.
