Based on some understanding of quartz ceramic products,it can be known that they have certain thermal properties during use,so they do have strong advantages in high temperature resistance.So,what are the main introductions about their thermal performance knowledge?

1、The high-temperature creep of quartz ceramic products will have a sharp increase stage and a stopping stage.Once the temperature reaches the deformation initiation temperature,its deformation amount increases rapidly,showing a linear proportional relationship.
2、Low thermal conductivity and high contact thermal resistance.Its thermal conductivity will increase correspondingly with the increase of temperature,and the rate of increase in thermal conductivity is slower within the temperature range below 1200℃.
3、When the temperature exceeds 1200℃,it will grow exponentially.It is precisely because of the low coefficient of linear expansion of quartz ceramic products that they also have considerable thermal stability.
4、The dielectric constant is much lower than the temperature dependent change in the tangent of the electrical loss angle.Like other high-temperature ceramics such as alumina,it can be used as an insulation material and is also a good material for missile and radar antenna covers.
5、Quartz ceramic products have a relatively low thermal expansion number,so they have good resistance to thermal vibration.Crystallization is the process of precipitating silicon dioxide crystals at high temperatures,and it is also a physical phenomenon that is relatively taboo in crystal growth processes.The high purity still has a significant impact on the physical parameters of crystals and the lifetime of non-equilibrium minority carriers.
The thermal performance of quartz ceramic products is relatively more obvious.In fact,when we apply them,many places rely on its thermal performance advantages to achieve it.In practical applications,its thermal performance can be reflected everywhere.
