In this study, the SPS conditions of Li4SiO4 powders produced by combustion synthesis were investigated. There is no study on the sinteringSintering of Li4SiO4 powders with SPS in the literature. Therefore, this study has made an innovative contribution to the literature. The combustion synthesis products were first ground by hand in an agate mortar. Then, the powders were placed in a graphite mold and pre-pressure of 10 MPa was applied with the help of an axial hydraulic press. In this way, it was aimed to obtain a compact product with a theoretical densityDensity of 100%, a diameter of 50 mm, and a thickness of 5 mm. The mold was then wrapped with a graphite blanket and placed inside the sinteringSintering chamber. All SPS experiments were conducted in a vacuum atmosphere. For each experiment, the heating rate was set at 100 °C/min and the sinteringSintering time was 5 min.

摘要

In this study, the SPS conditions of Li4SiO4 powders produced by combustion synthesis were investigated. There is no study on the sinteringSintering of Li4SiO4 powders with SPS in the literature. Therefore, this study has made an innovative contribution to the literature. The combustion synthesis products were first ground by hand in an agate mortar. Then, the powders were placed in a graphite mold and pre-pressure of 10 MPa was applied with the help of an axial hydraulic press. In this way, it was aimed to obtain a compact product with a theoretical densityDensity of 100%, a diameter of 50 mm, and a thickness of 5 mm. The mold was then wrapped with a graphite blanket and placed inside the sinteringSintering chamber. All SPS experiments were conducted in a vacuum atmosphere. For each experiment, the heating rate was set at 100 °C/min and the sinteringSintering time was 5 min.
