In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are polycrystalline, polyphase, inorganic, non-metallic, porous, and heterogeneous. They are typically … Zobraziť viac Refractory materials must be chemically and physically stable at high temperatures. Depending on the operating environment, they must be resistant to thermal shock, be chemically inert, and/or have specific ranges of Zobraziť viac Refractory materials are useful for the following functions: 1. Serving as a thermal barrier between a hot medium and the wall of a containing vessel 2. Withstanding physical stresses and preventing erosion of vessel walls due to the hot medium Zobraziť viac All refractories require anchorage systems such as wire formed anchors, formed metal (for example, hexmetal) or ceramic tiles to support the refractory linings. The anchorage used … Zobraziť viac Refractories are classified in multiple ways, based on: 1. Chemical composition 2. Method of manufacture 3. Fusion temperature 4.
