An SPS-RS Technique for the Fabrication of SrMoO Powellite Mineral-like Ceramics for Sr Immobilization.

This paper reports a method for the fabrication of mineral-like SrMoO ceramics with a powellite structure, which is promising for the immobilization of the high-energy Sr radioisotope. The reported method is based on the solid-phase "in situ" interaction between SrO and MoO oxides initiated under spark plasma sintering (SPS) conditions. Dilatometry, XRD, SEM, and EDX methods were used to investigate the consolidation dynamics, phase formation, and structural changes in the reactive powder blend and sintered ceramics.

Spark Plasma Sintering of WC-Based 10wt%Co Hard Alloy: A Study of Sintering Kinetics and Solid-Phase Processes.

The paper describes the method for producing WC-10wt%Co hard alloy with 99.6% of the theoretical density and a Vickers hardness of ~1400 HV 0.5.
