Silicon carbide (SiC) particles are exciting structures because of their hardness, chemical inertness, and dielectric properties. In particular, absorption/emission properties in the mid-infrared range render them suitable for ambient temperature thermal emitters. However, synthesis uniform, spherical is still challenging. Here, we present a robust procedure based on carbothermal reduction sili...

In this work, we explored the possibility of producing fine near-spherical metallic particles via carbothermal reduction stainless steel dust. For purpose, carbothermally reduced dust under different temperatures and times by using a vertical tube furnace, with special focus on size morphology particles. High temperature long time favored reduction. The was almost completed after 10 min at 1300...

The use of copper anode slime (CAS) for the removal lead, bismuth, and arsenic is key to recovering precious metals. In this paper, vacuum differential gravimetry experiments combined with thermodynamic equilibrium calculations reveal effects temperature, system pressure, carbon concentration on interactions among Pb, Bi, As during reduction. content a direct factor limiting reduction reactions...
