Crystallization in ceramic
WebGlass-ceramics based on spinel compositions ranging from gahnite (ZnAl 2 O 4) toward spinel (MgAl 2 O 4) can be crystallized using ZrO 2 and/or TiO 2 as nucleating agents. These glass-ceramics can be made highly transparent, with spinel crystals on the order of 10–50 nm in size (Fig. 9).The phase assemblage consists of spinel solid-solution … WebMar 1, 2024 · Anorthite (CaO·Al 2 O 3 ·2SiO 2) is a common crystal in the ceramic material, with a Mohs hardness of 6 [8], a thermal expansion coefficient of 4.5 × 10 −6 /°C [8] and a refractive index of 1.57, close to 1.51 for glass phase [8, 21], so it can be chosen to develop high-hardness transparent glass-ceramic glazes for ceramic tiles.
