Abstract
AbstractIn order to inhibit the phase transition of quartz, the effects of BPO4 addition and sintering temperature on the structure and properties of quartz materials were studied. The results showed that the addition of 5 wt.% BPO4 successfully inhibited the formation of cristobalite. Samples with 5 wt.% BPO4 added exhibited the high cold modulus of rupture (15.59 MPa) and bulk density (1.92 g/cm3) sintered at 1200°C–1400°C. In addition, BPO4 formed a glass phase sintered at 1200°C–1400°C and distributed between SiO2 particles, filling pores and densifying the material. Therefore, the prepared quartz‐based ceramics with BPO4 have broad potential in the field of medium and high temperatures, and can be applied to aerospace and other fields.
