Preparation and characterization of MgO-Al2O3-SiO2 glass-ceramics with different MgO/Al2O3 ratio and La2O3 addition

Impacts of substituting magnesium with zinc on crystallization behaviors in an aluminosilicate glass

“…Due to their excellent microwave performances, 1 high mechanical properties, 2 adjustable coefficient of thermal expansion, 3 and possible applications in various novel fields, [4][5][6] for example, electronic packing devices, millimeter-wave dielectrics or hard disk substrates, glass ceramics in the MgO-Al 2 O 3 -SiO 2 system have been extensively studied over the past several decades. To alter the nature of exclusive surface crystallization in the stoichiometric cordierite composition (2MgOÁ2Al 2 O 3 Á 5SiO 2 ), extensive research has focused on nucleating agents, such as TiO 2 , ZrO 2 , CeO 2 , or P 2 O 5 .…”

Effect of Al2O3 on Crystallization, Microstructure, and Properties of Glass Ceramics Based on Lead Fuming Furnace-Slag

“…When a higher amount of Al 2 O 3 is added, partial Al 3+ exists as [ AlO 5 ] or [ AlO 6 ] and as a positive ion outside the silica backbone, which increases the crystallinity, decreases the viscosity, and weakens the structural strength of the glass [8,9]. Many researchers have reported on the influence of Al 2 O 3 on the structure and properties of glass ceramics based on solid waste [10][11][12][13][14][15][16], indicating that the addition of an amount of Al 2 O 3 has a significant impact on the structure and properties of glass ceramics. However, little research about the crystallization behavior of glass ceramics prepared based on LFFS influenced by the addition of Al 2 O 3 has been reported.…”
