High refractory bricks, also known as fire bricks, are specialized ceramic or inorganic materials designed to withstand extreme temperatures, high heat, and aggressive chemical environments without degrading. They are manufactured from materials like alumina and silica to maintain structural integrity under intense heat and are primarily used to line furnaces, kilns, incinerators, and reactors in industries like steel, cement, and glass manufacturing.  

"Mideum" likely refers to "Medium" duty refractory bricks, which are firebricks designed to withstand high temperatures, chemical attack, and mechanical stress in industrial applications like kilns and furnaces. They offer good thermal resistance, high compressive strength, and a moderate fusion point. Medium-duty bricks are typically made from fireclay and are a type of firebrick, with their properties categorized based on chemical composition and performance.
