Crystallization mechanism and kinetics of a Fe-diopside (25CaO·25MgO·50SiO2) glass–ceramic

The Effect of the Chemical Composition on Mechanical Properties of CMAS Diopside Glass Ceramics

“…Therefore, GCs are inorganic and non-metallic materials with both glassy and crystalline phases. Because of the presence of crystalline phases in the residual and continuous glassy phases, GCs have a variety of unusual mechanical, electrical, optical and magnetic properties, which make GCs widely used in industrial areas such as architecture, building, optics, electronics and domestics [1,[3][4][5]. Among these features, the superior mechanical properties are significant since the crystalline phase in GCs can contribute strength and the glassy phase can offer ductility [6,7].…”

“…Some common and important crystalline phases nucleated in the CMAS system are diopside (CaO•MgO•2SiO 2 ), anorthite (CaO•Al 2 O 3 •2SiO 2 ) and cordierite (2MgO•2Al 2 O 3 •5SiO 2 ) and most of these crystalline phases have chemical stability [14]. Among these crystalline phases, the diopside phase can make the CMAS GCs have superior mechanical properties compared to others, which makes the diopside GCs have a wide range of applications [3,[15][16][17][18]. Moreover, the CaO-MgO-SiO 2 glass systems (CMS) are shown to have high biocompatibility and bioactivity and stimulate new bone growth [15][16][17]19].…”

“…The mechanical properties of diopside GCs in the CMAS system can be controlled by many factors, such as the temperature, chemical composition, nucleating agents, crystal size, etc. [3,15,17]. Most previous works have focused on the effect of the sintering temperature and the addition of various nucleation agents, such as ZrO 2 , B 2 O 3 and P 2 O 5 [3,20,21].…”

“…[3,15,17]. Most previous works have focused on the effect of the sintering temperature and the addition of various nucleation agents, such as ZrO 2 , B 2 O 3 and P 2 O 5 [3,20,21]. To make the diopside GCs work well in biomedical applications, it is necessary to systematically evaluate the strength and fracture toughness, so that they can fit as closely as possible with the corresponding biological tissues, such as cortical bone, trabecular bone and dentine [22,23].…”

Ultrahigh hardness Li2O–MgO–Al2O3–SiO2 glass–ceramics containing multiphase nanocrystals

“…Li 2 O-Al 2 O 3 -SiO 2 (LAS) glass-ceramics have attracted extensive attention in recent years because of their excellent properties, such as ion conduction, 1,2 low coefficient of thermal expansion (CTE), 3,4 high mechanical strength, [5][6][7] for applications in lithium battery, 8 fire resistance safe glass, [9][10][11][12] protection glass for electronic devices, [13][14][15][16][17] photonics for photoluminescence enhancement from the local surrounding change of rare-earth ions in transparent glass-ceramics, [18][19][20] and so on. The precursor glasses were controllably crystallized nanometer and micrometer scale crystals based on Li-Si-O or Li-Al-Si-O [21][22][23] for strength improvement.…”
