Quartz ceramic products are different from ordinary ceramics in that they have strong heat resistance.However,we cannot relax our vigilance because of this characteristic.In some cases,there may be a transformation of quartz crystal structure.When this happens,we must pay close attention to it because it can bring many hazards.The following will provide a detailed introduction.
1、Reason
At high temperatures(above approximately 573℃),alpha quartz undergoes a crystal transformation,transforming into beta quartz.However,during the cooling process,β-quartz may transform back intoα-quartz again.This transformation process may cause volume changes in quartz crystals within quartz ceramic products,resulting in stress and cracks,which naturally pose a hazard.
2、Harm
1.Ceramic products are prone to damage
Quartz is one of the important raw materials in the production of quartz ceramic products.If it containsβ-quartz,it is easy to undergo crystal transformation during the production of products,resulting in micro cracks,corner edges and other problems on the surface of ceramic produ
