A novel method of silicon carbide coating to protect porous carbon against oxidation

Coating dense silicon carbide layer on artificial graphites to achieve synergistically enhanced thermal conductivity and electronic insulation of polymer composites

“…Ceramic coatings generally lead to enhancing the high-temperature stability of carbon materials in the air atmosphere due to their high melting point, outstanding thermal shock stability, and excellent antioxidant properties. 31 Therefore, thermogravimetry (TG) was operated under an air condition to investigate the high-temperature resistance of coated samples. As can be seen from Figure 3d and Figure S7, the TG curves start to deviate from 100% at 643 C for the original SG, 680 C for SG@SiC-1, and 738 C for SG@SiC-2.…”

Rapid Synthesis of Patterned Silicon Carbide Coatings Using Laser‐Induced Pyrolysis and Crystallization of Polycarbosilane

“…Silicon carbide (SiC) is an essential material with extraordinary characteristics such as high thermal stability, chemical inertness, corrosion resistance, and semiconducting behavior. [ 1,2 ] These properties have allowed for the use of SiC in oxidation and corrosion‐resistant coatings, [ 3,4 ] transistors for harsh environments, [ 5 ] field emitters, [ 6 ] catalyst supports, [ 7 ] sensors, [ 8 ] membranes, [ 9 ] and photocatalysis, among others [ 10,11 ]…”

[15,16] CVD produces lowdefect SiC, but the method is expensive and not easily scalable.…”
