The effect of different amount of Li₂ZrO₃(LZ) (0-15wt%) addition on the properties of composite Li₄SiO₄ (LS) ceramic pebbles was studied. The Li₄SiO₄-Li₂ZrO₃ composite powder was prepared using solid state route at a calcination temperature as low as 900 °C via in-situ method. The composite pebbles were fabricated using a cost-effective and simple technique called extrusion-spherodization. The sintered pebbles were characterized for density, grain size, pore size distribution, crush load and moisture stability. The composite pebbles showed good sintered density (∼87.1%) for LS-5wt% LZ in comparison to LS pebbles (∼80%) when fired at 1000 °C. Moreover, the LS grain size in the composite pebble was significantly reduced by ∼19.7% when compared to LS pebbles. We also found that the average crush load value of the LS-5wt% LZ composite pebbles was improved by nearly 77% (30 N) to that of the pure LS pebbles (17 N). The LS-5wt% LZ pebbles showed excellent stability to moisture in terms of phase and mechanical crush load retention after 30 days of exposure to humidity. The results achieved in this work were found to be fit to the desired properties for use as a ceramic solid breeder.

研究了不同添加量的Li ₂ ZrO ₃（LZ）（0-15wt％）对复合Li ₄ SiO ₄（LS）陶瓷卵石性能的影响。Li ₄ SiO ₄ -Li ₂ ZrO ₃通过固态方法在原位煅烧温度低至900°C的条件下制备复合粉末。复合卵石是使用一种经济高效且简单的技术（称为挤出球化）制造的。对烧结的卵石进行了密度，粒度，孔径分布，压碎载荷和水分稳定性的表征。与在1000°C焙烧的LS卵石（〜80％）相比，LS-5wt％LZ的复合卵石显示出良好的烧结密度（〜87.1％）。此外，与LS卵石相比，复合卵石中的LS晶粒尺寸显着降低了约19.7％。我们还发现，与纯LS卵石（17 N）相比，LS-5wt％LZ复合卵石的平均压碎载荷值提高了近77％（30 N）。LS-5wt％LZ卵石在暴露于湿气30天后，在相和机械破碎载荷保持方面表现出对水分的出色稳定性。发现在这项工作中获得的结果适合用作陶瓷固体育种者的所需特性。
