In the present study, an original spark plasma sintering-reactive synthesis (SPS-RS) method for mineral-like ceramic materials based on SrAl₂Si₂O₈ feldspar-like skeleton structure was used for the first time, promising solid-state matrices for reliable immobilization of high-energy ⁹⁰Sr. The method is based on the “in-situ” reaction of a mixture of SrO, Al₂O₃ and SiO₂ oxides when heated by a unipolar pulsed current under compacting pressure. The phase and elemental composition structure were studied. The dynamics of the consolidation of the reaction mixture of oxides was studied in the range of 900–1200 °C. The study found the temperature of the high-speed (minutes) SPS-RS formation of single-phase SrAl₂Si₂O₈ composition ceramic in the absence of intermediate reaction products with a relative density of up to 99.2% and compressive strength up to 145 MPa and a strontium leaching rate of 10⁻⁴g/cm²·day.

在本研究中，首次使用基于 SrAl ₂ Si ₂ O ₈长石类骨架结构的类矿物陶瓷材料的原始放电等离子体烧结反应合成（SPS-RS）方法，有前途的固态基质用于可靠固定高能⁹⁰ Sr。该方法基于SrO、Al ₂ O ₃和 SiO ₂混合物的“原位”反应在压制压力下通过单极脉冲电流加热时的氧化物。研究了相和元素组成结构。在 900-1200 °C 范围内研究了氧化物反应混合物的固结动力学。研究发现，在没有中间反应产物的情况下，单相 SrAl ₂ Si ₂ O ₈复合陶瓷高速（分钟）SPS-RS 形成的温度，相对密度高达 99.2%，抗压强度高达145 MPa和10 ^-4 g/cm ² ·天的锶浸出率。
