Mullite-Based Ceramics from Mining Waste: A Review

Mullite (3Al2O3·2SiO2) is an aluminosilicate characterized by excellent physical properties, which makes it an important ceramic material. In this way, ceramics based on mullite find applications in different technological fields as refractory material (metallurgy, glass, ceramics, etc.), matrix in composite materials for high temperature applications, substrate in multilayer packaging, protective coatings, components of turbine engines, windows transparent to infrared radiation, etc. However, mullite is scarce in nature so it has to be manufactured through different synthesis methods, such as sintering, melting-crystallization or through a sol-gel route. Commonly, mullite is fabricated from pure technical grade raw materials, making the manufacturing process expensive. An alternative to lowering the cost is the use of mining waste as silica (SiO2) and alumina (Al2O3) feedstock, which are the necessary chemical compounds required to manufacture mullite ceramics. In addition to the economic benefits, the use of mining waste brings out environmental benefits as it prevents the over-exploitation of natural resources and reduces the volume of mining waste that needs to be managed. This article reviews the scientific studies carried out in order to use waste (steriles and tailings) generated in mining activities for the manufacture of clay-based ceramic materials containing mullite as a main crystalline phase.

“…Mullite has been synthesized using various methods, such as sol‐gel process, chemical syntheses, 13,14 co‐precipitation, 6,15 hydrothermal reaction, 16,17 flash combustion, 18–19 and chemical vapor deposition 20,21 . However, the production of high‐purity and high‐density mullite is still a challenge.…”

Mullite is an excellent ceramic material due to the unique properties, such as low coefficient of thermal expansion, high corrosion resistance to acid and alkali, high-temperature creep resistance, strong thermal shock resistance, high chemical and thermal stability, high permeability, and excellent mechanical properties. [1][2][3] Mullite ceramics have been widely utilized as metallurgical, glass, ceramic, and other industrial refractory materials. [4][5][6] They are also widely used as heatresistant materials, such as crucibles, protective tubes, and thermocouple tubes for electronic packaging. [7][8][9] Other applications include window materials under harsh chemical conditions and mechanical stress at high temperatures. [10][11][12] Mullite has been synthesized using various methods, such as sol-gel process, chemical syntheses, 13,14 co-precipitation, 6,15 hydrothermal reaction, 16,17 flash combustion, [18][19] and chemical vapor deposition. 20,21 However,

“…Para isso, utilizam-se reações químicas entre diversos tipos de compostos. Com base na literatura, o método químico mais utilizado para produção de mulita é o método sol-gel (CHU et al, 1997;DONG et al, 2019;ILIĆ et al, 2020), que faz com que a temperatura mínima de formação de mulita seja inferior à temperatura utilizada pelos métodos convencionais.…”
