ELECTRIC (JOULE) HEATERS
In electric furnaces with a neutral atmosphere or a vacuum, heaters made of carbides of refractory metals (zirconium, niobium, tantal, hafnium) are used. The most refractory among them is hafnium carbide (T melt = 4160 K). Metal heaters are usually fabried
Fire brick - Wikipedia
Fire bricks have an aluminium oxide content that can be as high as 50–80% (with correspondingly less silica). High temperature appliions The silica firebricks that line steel-making furnaces are used at temperatures up to 3,000 F (1,649 C), which would melt many other types of ceramic, and in fact part of the silica firebrick liquefies.
