A new titanate wasteform, Synroc-Z, was developed to contain minimal host phases for actinides and thus better suit the EURO-GANEX process. The processing conditions, waste loading and surface roughness were varied, and their effects on wasteform durability and microstructure were examined. Hot uniaxial pressing temperature was the most important factor in controlling density (<0.5 vol% porosity) and phase composition. Synroc-Z was found to have similar aqueous durability to Synroc-C. Leached samples formed Ti-oxide films and crystals on their surfaces as found by other researchers.

At low waste loadings (<20 wt%), Synroc-Z showed slightly poorer durability performance than Synroc-C owing to its greater perovskite content (30 vs. 20 wt% respectively). However, at 35 wt% waste loading, Synroc-Z maintained its durability performance. This result is explained by the higher volume fraction of buffer phase, rutile, which allows greater flexibility for waste loading.

开发了一种新的钛酸酯废料Synroc-Z，以减少contain系元素的宿主相，从而更适合EURO-GANEX工艺。改变了加工条件，废物装载量和表面粗糙度，并考察了它们对废物形态耐久性和微观结构的影响。热单轴压制温度是控制密度（<0.5 vol％孔隙率）和相组成的最重要因素。发现Synroc-Z具有与Synroc-C相似的水性耐久性。其他研究人员发现，浸出的样品在其表面上形成了Ti氧化物膜和晶体。

在低废物负荷（<20 wt％）下，Synroc-Z的钙钛矿含量较高（分别为30和20 wt％），因此其耐久性能比Synroc-C差一些。但是，在废物含量为35 wt％时，Synroc-Z仍保持其耐久性能。缓冲相金红石的体积分数较高，可以解释此结果，这为废物装载提供了更大的灵活性。
