<P> The silica firebricks that line steel - making furnaces are used at temperatures up to 1648 ° C ( 3000 ° F ) , which would melt many other types of ceramic , and in fact part of the silica firebrick liquefies . High - temperature Reusable Surface Insulation ( HRSI ) , a material with the same composition , was used in the insulating tiles of the Space Shuttle . </P>
