These refractories are primarily composed of mullite, a mineral formed from the reaction of alumina and silica at elevated temperatures. The material's unique properties make it indispensable in industries such as steel, glass, cement, and petrochemicals, where extreme heat and harsh conditions are common. Mullite refractories are available in various forms, including high-purity fused mullite, ordinary fused mullite, and sintered mullite, each tailored for specific industrial applications.

Market growth is driven by increasing demand from the steel and glass industries, where mullite refractories are used in furnaces, kilns, and other high-temperature processing equipment. USD 1.78 billion USD 2.63 billion 0.05%
Global iron and steel industry, which accounts for over 60% of refractory material consumption, is a primary driver for mullite refractories. With steel production projected to exceed 1,950 million metric tons by 2025, manufacturers increasingly require highperformance refractory solutions that can withstand extreme temperatures above 1500°C. Mullite's superior thermal shock resistance and mechanical strength make it indispensable for blast furnaces, ladles, and tundishes.
