WebThe application of nanotechnology in refractories is mainly to introduce nanopowder into refractories. High purity corundum powder introduced into α-Al2O3 nanopowder and α-Al2O3 powder can promote solid-phase sintering and improve the sintering performance of the product. In MgO-C composite refractory, the use of nano-carbon powder to replace ... Webproduct. However, at each glass furnace exists degraded material due to the interaction of the refractory and the glass melt. It is necessary to reduce this as a consequence of rising prices for raw materials and energy. The optimisation of the existing refractory by changing the composi-tion (e.g. the ZrO 2 weight percentage) will be the non ...

Saint-Gobain Performance Ceramics & Refractories

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 • Fire brick • Masonry oven • Refraction (metallurgy) Zobraziť viac Refractories are classified in multiple ways, based on: 1. Chemical composition 2. Method of manufacture Zobraziť viac All refractories require anchorage systems such as wire formed anchors, formed metal (for example, hexmetal) or ceramic tiles to support … Zobraziť viac WebFor all of the glass industry furnaces, our silica, alumina-silica, alumina, zircon and chrome-containing high-performance refractories meet the customer requirements.
