What is Refractory? In the most general sense, refractory is material that can withstand corrosive conditions at high temperatures while providing either thermal insulation or conduction. Refractory may need to withstand extreme heat and thermal shock, pressurized conditions, corrosion due to acidic or basic conditions, abrasion from rough conditions, along with many other factors once in situ. The specific requirements of refractories will vary based on the area of application and the conditions in which they will be used. As an example, hog fuel boilers have to contend with abrasion as fuel moves around inside the boiler as it burns; refractory is used as a protective measure against these abrasive conditions.   Where is Refractory Used? Refractory is versatile in its uses and can be seen in small personal outdoor ovens, to heat shields on spacecraft, to lining boilers and furnaces. The use of refractory can increase the efficiency of the furnaces and boilers by limiting heat loss and protecting critical components. What is Refractory made from? Both natural and synthetic materials are used to manufacture refractory. The material specifications and component proportions can be adjusted to optimize the desired function of the refractory whether that be high heat retention, load bearing capability, insulating properties, or reduced spalling, among many, many others. Materials such as alumina, silica, chromite, dolomite, magnesite, plus others, are mined, refined, and combined in the desired proportions to meet situation needs. Refractory Forms Refractory comes in three common forms: molded, monolithic, and fiber. Below are descriptions and photos of each. Molded refractory, which includes bricks, tiles, and special shapes, is available in standard sizes and compositions but can be customized in both aspects as needed. With proper application, molded refractory can be long-lasting, maintain structural integrity at operating temperatures, resist excessive cracking, an
