  • Description

    Imported Quartz Disc can be transparent or milky white. These discs can withstand up to 1100 degree centigrade. It is most important to note that Quartz Disc can withstand very high thermal shock (1000 degree centigrade to room temperature).

    The transparent Quartz Disc is obtained through different types of raw materials because that includes natural or synthetic quartz sand. These are highly resistant to thermal shock due to the extremely low coefficient of thermal expansion because they have excellent electrical strength that offers stability under temperature variation.

    Our range of Quartz Disc is developed in our company by using high purity fused quartz as raw material and fabricating with advanced ceramic technology.
