Pyroplastic deformation behavior of vitreous porcelain bodies in presence of spodumene

Beta-spodumene:Na2CO3:NaCl system calcination: A kinetic study of the conversion to lithium salt

“…The visual result, observed in Fig. 4, was the densification of the material and the increase in the porosity of the cones (923 K), obtained by eliminating CO 2 as a result of the partial decomposition of the carbonate and the higher conversion rate (Hopa and Özel, 2017;Ren and Du, 2016). Data from Table 2 show that in the calcination, betaspodumene behaved as a material with refractory properties.…”

Low water absorption and pyroplastic deformation of alumina‐strengthened porcelain with petalite and Gairome clay

“…16 Thus, the addition of a mineral containing lithium, such as petalite, spodumene, lepidolite, hectorite, etc, is an attractive option to control the amount and viscosity of the liquid phase during porcelain firing. 16,17,18 Particularly, petalite not only softens the glass matrix in the porcelain but also enhances mullite crystallization. Although doping with Li + has significant potential to obtain a low WA and PI, studies on the PD of Li + doped porcelain have rarely been reported.…”

“…Although doping with Li + has significant potential to obtain a low WA and PI, studies on the PD of Li + doped porcelain have rarely been reported. 18 Even in the literature, PI has only been investigated at a certain firing temperature. Therefore, the effect of the Li + doping of porcelain on the balance between a low WA and low PI in a wide MFTs range has not been clarified yet.…”

“…Doping with Li + is more effective than with other alkali and alkaline earth ions for decreasing the softening temperature of silicate glass because it significantly disrupts the SiO 4 tetrahedral network 16 . Thus, the addition of a mineral containing lithium, such as petalite, spodumene, lepidolite, hectorite, etc, is an attractive option to control the amount and viscosity of the liquid phase during porcelain firing 16,17,18 . Particularly, petalite not only softens the glass matrix in the porcelain but also enhances mullite crystallization.…”

“…Particularly, petalite not only softens the glass matrix in the porcelain but also enhances mullite crystallization. Although doping with Li + has significant potential to obtain a low WA and PI, studies on the PD of Li + doped porcelain have rarely been reported 18 . Even in the literature, PI has only been investigated at a certain firing temperature.…”
