根据wiki,大猩猩玻璃工艺流程与LK99工艺原理类似,高温离子置换产生材料应力。
LK99 wiki
LK-99的化学成分约为Pb9Cu1(PO4)6O,与纯铅磷灰石 (Pb10(PO4)6O)相比[5]:5,有大约四分之一的Pb2+被Cu2+离子取代[2]:9。研究者稱利用Cu2+离子(87皮米)部分替代133皮米的Pb2+离子可以使材料体积减少0.48%,从而在材料内部产生内应力[2]:8。
大猩猩玻璃
During its manufacture, the glass is toughened by ion exchange. The material is immersed in a moltenalkaline potassium salt at a temperature of approximately 400 °C (750 °F),[22] wherein smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath. The larger ions occupy more volume and thereby create a surface layer of high residual compressive stress, giving the glass surface increased strength, the ability to contain flaws,[23] and overall crack-resistance,[24] making it resistant to damage from everyday use.[22]
