完全致密、透明的多晶陶瓷是通过直接和完全的玻璃结晶而获得的。先前未报道的组合物BaAl4O7证明了这一点，它具有两种微米粒度的正交晶型，在可见光范围内都是透明的。这种创新的透明多晶陶瓷合成路线将有助于发现新的具有成本效益的透明陶瓷应用化学方法。
Fully dense, transparent polycrystalline ceramics are simply obtained by direct and complete crystallization from glass. This is demonstrated for the previously unreported composition, BaAl4O7, which exhibits two orthorhombic polymorphs with micrometer grain size, both optically transparent in the visible range. This innovative synthetic route to transparent polycrystalline ceramics should facilitate the discovery of new cost-effective chemical methods for transparent ceramic applications.
