The cement is made by fusing together a mixture of a calcium-bearing material (normally calcium oxide from limestone) and an aluminium-bearing material (normally bauxite for general purposes, or refined alumina for white and refractory cements).
Refractory bricks in a torpedo car used for hauling molten iron. In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures. [1]
High-temperature applications, such as masonry ovens and the like, generally require the use of a refractory cement; concretes based on Portland cement can be damaged or destroyed by elevated temperatures, but refractory concretes are better able to withstand such conditions.
With a projected Compound Annual Growth Rate (CAGR) of 4.7% from 2024 to 2034, the demand for refractory cement is anticipated to grow to USD 37,707.6 million by 2034. Understanding the Refractory Cement Market. The refractory cement market is driven by its critical role in high-temperature applications across various industries.
After building of a new refractory-lined industrial furnace or equipment, or refractory maintenance or relining of existing equipment, a necessary step is the start-up of the operation, which usually involves heating-up the unit in a controllable way, in order to prevent spalling or shortening of the materials' predicted lifetime.
Refractory metals are a class of metals that are extraordinarily resistant to heat and wear. The expression is mostly used in the context of materials science , metallurgy and engineering . The definition of which elements belong to this group differs.
