The minimum firing temperature of the specimens is 1200°C, and the soaking time at this temperature should not be less than 6 h. The maximum firing temperature is 1400°C with a 3-h soak. Silicon carbide refractories for the linings of aluminum electrolyzers need to be fired with a staged cycle, with soaking periods at 1200 and 1400°C.

Silicon Carbide (SiC): Properties, Production

Silicon carbide’s resistance to high temperature and thermal shock is the property that allows SiC to be used in the manufacturing of fire bricks and other refractory materials. The decomposition of silicon carbide starts at 2000°C [2]. Conductivity. If SiC is purified, its behaviour manifests that of an electrical insulator.

Silicon Carbide Brick-Refractory Brick

Chemical use: since silicon carbide can be decomposed in molten steel, it can react with oxygen and metal oxides in molten steel to form carbon monoxide and silicon slag. Therefore, it can be used as a refining agent for steelmaking, that is, deoxidizer for steelmaking and modifier for cast iron.

Firing silicon carbide refractories in a …

Silicon carbide refractories for the linings of aluminum electrolyzers need to be fired with a staged cycle, with soaking periods at 1200 and 1400°C. During the firing of specimens of silicon carbide and silicon in a nitrogen atmosphere at 1200–1400°C, the silicon is converted almost completel

Silicon carbide refractories are available as alkali-resistant refractories. This type of refractory greatly varies in alkali resistance depending on bond used.

Properties of silie-bonded silicon …

Abstract. Silie-bonded silicon carbide refractories have been prepared by reaction bonding. Mullite or sillimanite was used for bonding of silicon carbide. The percentage of silie bond was varied from 15 to 30 wt.%. Molybdenum disilie (4 wt.%) has been used as an infiltrant for silicon carbide refractories.

Resistance of silicon carbide refractories …

The effect of alkalis, slag, and carbon monoxide on silicon carbide and nitride was studied at elevated temperatures up to 1550°C. It was established that silicon carbide is destructed most rapidly at 1200°C under the action of the investigated factors. The properties of silicon nitride virtually do not change on heating up to 1400°C in the presence of carbon monoxide; one …
