Abstract

Samarium monosulfide (SmS) is a unique tensometric material. For the first time, SmS ceramics for magnetron sputtering films were synthesized. A powder of up to 100 mol% SmS was produced via the reaction of γ-Sm₂S_2.98 with excess metallic samarium vapor. The conditions for target and side reactions were determined. SmS ceramic targets were fabricated by pressing under standard conditions and annealed at high temperatures. Ceramic properties—density, hardness, and compressive strength—improved with increasing pressing pressure. Conditions for stable magnetron discharge over the SmS target were established. The composition of films deposited on silicon substrates varies with the substrate-to-target angle, transitioning from SmS_1.9 to SmS. During magnetron discharge, SmS dissociates into samarium and sulfur, with their distribution approximated by angular equations. High-mass Sm and SmS particles distribute radially, while sulfur concentration forms an ellipse elongated toward low angles. The deposition angle range for SmS was determined.

单硫化钐陶瓷：制备与性能

单硫化钐是一种独特的张力拉伸材料。首次合成了用于磁控溅射薄膜的SmS陶瓷。通过γ-Sm2S2.98与过量的金属钐蒸气反应，制备了SmS含量高达100 mol%的粉末。确定了靶反应和副反应的条件。采用标准条件下压制和高温退火法制备了SmS陶瓷靶材。陶瓷的性能——密度、硬度和抗压强度——随着压力的增加而提高。建立了磁控管在SmS靶上稳定放电的条件。沉积在硅衬底上的薄膜的组成随着衬底与靶角的变化而变化，从SmS1.9过渡到SmS。在磁控管放电过程中，SmS解离成钐和硫，其分布近似于角方程。高质量的Sm和SmS粒子呈放射状分布，而硫浓度则呈低角度椭圆形。确定了SmS的沉积角度范围。

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
