| مستخلص: |
Forsterite raw material for ceramic proppant was synthesized by solid-phase sintering method with magnesite tailings and silica as raw materials, which is not only beneficial to the secondary resource utilization of magnesite tailings, but also can replace natural forsterite as raw material for ceramic proppant, providing a new direction for the preparation of raw material for ceramide proppant. The effects of different firing temperatures on the properties of synthetic forsterite were investigated by characterization of phase composition, microstructure and cold physical properties. The acid solubility of samples at different firing temperatures was compared. The results show that when the firing temperature are 1 400 ~1 550 °C for 3 h, the main phase of samples is forsterite. With the firing temperature increases, the grain size of forsterite increases continuously, which improves the cold physical properties and acid resistance of samples. However, an excessively high firing temperature lead to an increase of glassy phase content in samples, affecting its performance. When the firing temperature is 1 500 °C, cold mechanical properties of samples reach the maximum value, and acid solubility is the lowest. [ABSTRACT FROM AUTHOR] |
