The mixture was annealed at 450 °C for stable anatase-phase nanoparticles.
After the solvent evaporation, the mixture was annealed under flow of argon at 675 °C for 2 h.
After that, the mixture was annealed at 1000 °C for 5 min in an Ar atmosphere, and the final product was ground and used as the active material for lithium-ion batteries.
It involves mixing of element or alloy powders with additives and lubricants, and the mixture is annealed in a controlled atmosphere furnace (at 900 °C) so as to bond the particles metallurgically [15].
This process is attributed to the cobalt stabilizing the graphitic structure during ball milling, thus reducing the degree of lattice-disorder.When the mixture is annealed, well-ordered carbon strips encapsulating cobalt nanoparticles are observed in the presence of cobalt.Annealing reorganizes the disordered structures and 10% cobalt loading is more effective than a 1% loading in this process.
Then the mixture was annealed in Ar up to 950 °C for 3 h with a heating rate of 3 °C/min.
The resulting mixture was annealed from 50 to 4 °C overnight prior to native PAGE and AFM analysis.
In mixtures of CH4+D2O+18O2, the samples were annealed at 973 K and SIMS analysis was carried out on the quenched samples.
Electrochemical measurements demonstrated that when the mixture of carbon and triphenylphosphine were annealed at 800 °C, the activity of the corresponding catalyst (Pd/P-C-800) was enhanced as a factor of 3.14 than the Pd/C catalyst.
Catalyst mixtures with vanadia contents up to 10% were annealed in air in the temperature range from 400 to 1200 °C.
