A refractory material is one that retains its strength at high temperatures. ASTM C71 defines refractories as non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above 1,000 Â°F (811 K; 538 Â°C).cidic refractories consist of mostly acidic materials like alumina (Al 2 O 3) and silica (SiO 2). They are generally not attacked or affected by acidic materials, but easily affected by basic materials. They include substances such as silica, alumina, and fire clay brick refractories.
