根據wiki,大猩猩玻璃工藝流程與LK99工藝原理類似，高溫離子置換產生材料應力。
LK99 wiki
LK-99的化學成分約為Pb9Cu1(PO4)6O，與純鉛磷灰石 (Pb10(PO4)6O)相比[5]:5，有大約四分之一的Pb2+被Cu2+離子取代[2]:9。研究者稱利用Cu2+離子（87皮米）部分替代133皮米的Pb2+離子可以使材料體積減少0.48%，從而在材料內部產生內應力[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]
