以稻壳灰（RHA）为原料，采用溶液燃烧法合成了Li4SiO4粉体。RHA是廉价的农业废弃物，很容易获得。发现在650℃下可制得相纯的Li4SiO4粉末。还观察到，粉末的相纯度取决于启动液的金属与燃料比。最后，在1000℃的温度下进行微波烧结，使合成的Li4SiO4致密化到理论密度的80%以上。
The present report demonstrates synthesis of Li4SiO4 powder through solution combustion route using silica from rice husk ash (RHA). RHA is cheap agricultural waste and can be easily procured. It is found that phase pure Li4SiO4 powder can be prepared at 650°C. It is also observed that phase purity of the powder depends on metal to fuel ratio of the starting solution. Finally, microwave sintering is carried out to densify the synthesized Li4SiO4 to more than 80% of theoretical density at a temperature 1000°C.
