Chlorine Trifluoride Gas

Abstract: 4H-silicon carbide epitaxial film was etched using chlorine trifluoride gas. The etch rate of C-face at 2-100 % and at various temperatures was 0.8 – 10 μm min-1, which was comparable to those of the silicon carbide substrates. The surface morphology observed after the etching was very smooth, in contrast to that of the substrate

Silicon Carbide Etching Using Chlorine Trifluoride Gas

Abstract The etch rate, chemical reactions and etched surface of β-silicon carbide are studied in detail using chlorine trifluoride gas. The etch rate is greater than 10 μm min-1 at 723 K with a flow rate of 0.1 \ell min-1 at atmospheric pressure in a horizontal reactor. The maximum etch rate at a substrate temperature of 773 K is 40 μm min-1 with a flow rate of 0.25 \ell min-1.

Silicon carbide - Wikipedia

Silicon carbide is an important material in TRISO-coated fuel particles, the type of nuclear fuel found in high temperature gas cooled reactors such as the Pebble Bed Reactor. A layer of silicon carbide gives coated fuel particles structural support and is the main diffusion barrier to the release of fission products.

Silicon carbide react with chlorine

Silicon carbide react with chlorine. SiC + 2Cl 2 SiCl 4 + C [ Check the balance ] Silicon carbide react with chlorine to produce silicon tetrachloride and carbon. This reaction takes place at a temperature near 100°C. [16] Other variants: Find another reaction. Our channel.

Bonding in Elements and Compounds Ionic Covalent Metallic

Silicon forms giant covalent molecules in which each Si atom is covalently bonded to 4 other Si atoms. Covalent bonds are strong (comparable to metallic bonds) and as each Si atom forms 4 of them all 4 bonds must be broken to separate the atoms and Si has a very high b.p., even higher than that of Al.

Etching of silicon carbide by chlorine - ScienceDirect

The reaction of Cl 2 with polycrystalline β-silicon carbide was studied by the modulated molecular beam-mass spectrometric detection method. The temperature range was 300–1000 K and beam intensities between 10 16 and 10 17 /cm 2 s were employed.

Kinetics of conversion of silicon carbide to carbide

Carbide derived carbon (CDC) is a new form of carbon produced by exposure of metal carbides to chlorine at temperatures in the range of 600–1200 °C [1, 2]. In this temperature range, chlorine will react with the metal component of the carbide to form a volatile product, leaving the carbon behind.

Effects of chlorine and alkali chlorides on corrosion of

Silicon carbide and other silicon-based ceramics obtain their oxidation resistance by the formation of protective silica films in oxygen containing environments. In the presence of chlorine or alkali chlorides, this film may not form, or may be unprotective, so that accelerated oxidation occurs.
