Description of Cobalt Granules, Cobalt Pellets

Cobalt pellets are high-purity metallic materials with excellent magnetic, thermal, and wear-resistant properties. Typically shaped as small, uniform cylinders or spherical pieces, they are designed for precise melting and alloying. These pellets are widely used in the production of superalloys, aerospace components, and magnetic materials, as well as in the synthesis of advanced catalysts. Their consistent shape and size enhance processing efficiency in demanding industrial and research applications.

Manufacturing method of Cobalt Granules, Cobalt Pellets

Cobalt pellets are commonly produced by casting or powder metallurgy techniques. In casting, molten cobalt is poured into molds to form small, uniform pellets, while powder metallurgy involves compressing cobalt powder into pellet shapes under high pressure and sintering them for durability. Both methods ensure consistent size, density, and purity for applications in alloying, electronics, and magnetic material production.

Spark Plasma Sintering of Cobalt Powders in Conjunction with High Energy Mechanical Treatment and Nanomodification

Spark plasma sintering (SPS) investigations were carried out on three sets of Co specimens: untreated, high energy mechanically (HEMT) pre-treated, and nanomodified powders. The microstructure, density, and mechanical properties of sintered pellets were investigated as a function of various pre-treatments and sintering temperatures (700–1000 °C). Fine-grained sinters were obtained for pre-treated Co powders; nano-additives tended to inhibit grain growth by reinforcing particles at grain boundaries and limiting grain-boundary movement. High degree of compaction was also achieved with relative densities of sintered Co pellets ranging between 95.2% and 99.6%. A direct co-relation was observed between the mechanical properties and densities of sintered Co pellets. For a comparable sinter quality, sintering temperatures for pre-treated powders were lower by 100 °C as compared to untreated powders. Highest values of bending strength (1997 MPa), microhardness (305 MPa), and relative density (99.6%) were observed for nanomodified HEMT and SPS processed Co pellets, sintered at 700 °C.
