Calcium carbide - Wikipedia

Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide.[3] The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC2 (the rest is

Novel Synthesis of Silicon Carbide Nanowires from e …

In this study a novel new process for the synthesis of silicon carbide nanowires from a voluminous and problematic waste stream, e-waste, is verified. Silicon carbide nanowires (SiC NWs) with diameters of 30–200 nm and length up to 10 μm were synthesized via the carbothermal reduction of two electronic waste (e-waste) components. The glass fraction of an obsolete computer monitor (GCM) was

Deep-level defects in n-type 6H silicon carbide induced …

Defects in He-implanted n-type 6H–SiC samples have been studied with deep-level transient spectroscopy. A deep-level defect was identified by an intensity with a logarithmical dependence on the filling pulse width, which is characteristic of disloion defects. Coined with information extracted from positron-annihilation spectroscopic measurements, this defect was associated with the

Density Functional Study of Interaction of Lithium with …

Interactions between a lithium atom or a lithium ion with pristine and Stone-Wales-defective (SW-defective) (5, 5) single-walled silicon carbide nanotubes (SiCNTs) were studied using density functional theory (DFT) with truned nanotube models. The results show that the lithium atom or ion prefers to interact with defective SiCNTs, although the increase of binding energy for Li+ bonding with

Diffusion of C13 and Si30 in silicon carbide was performed with isotopically enriched 4H-Si28C12∕natSiC heterostructures which were grown by chemical vapor phase epitaxy. After diffusion annealing at temperatures between 2000°C and 2200°C the Si30 and C13 profiles were measured by means of secondary ion mass spectrometry. We found that the Si and C diffusivity is of the same …
