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 products,which reduces the strength and stability of ceramic products.
2.Low production efficiency
Due to the transformation of quartz crystal structure,ceramic products may experience cracking,chipping,and other issues that require reprocessing or scrapping,thereby reducing production efficiency and increasing costs.
3.There are many customer complaints
If the quartz ceramic products produced suffer from cracking and other problems due to the transformation of quartz crystal structure,it will not only affect the product quality,but also lead to customer complaints and affect the brand image of the enterprise.
Through understanding the above hazards,we must take good care of quartz ceramic products in the future to avoid potential hazards caused by crystal transformation.During production,we must pay attention to the production process,carefully inspect the quality,and strictly control the production process.
