Application of Boron Carbide as Antioxidant Additive in Refractory Materials
Boron carbide is used as an antioxidant additive for low carbon magnesia carbon bricks and castables. It is used in key parts of high temperature resistance and erosion resistance in the iron and steel industry.

A boron carbide-graphite thermocouple consists of a graphite tube, a boron carbide rod, and a boron nitride bushing in between. In inert gas and vacuum, use temperature up to 2200 ℃. Between 600 and 2200 °C, the potential difference has a good linear relationship with temperature.

At present, the performance of low-carbon magnesia-carbon bricks is generally improved by improving the combined carbon structure, optimizing the matrix structure of magnesia-carbon bricks, and adding high-efficiency antioxidants. Among them, graphitized carbon black composed of industrial grade B4C and part of graphitized carbon black is used. The composite powder is used as a carbon source and antioxidant for low-carbon magnesia-carbon bricks, and good results have been achieved. The low-carbon magnesia-carbon bricks added with B4C have good general physical properties, oxidation resistance and thermal shock stability.
