It features high thermal shock stability, with actual products remaining unbroken and unpeeled even when exposed to 1600°C high temperatures. With a low thermal expansion coefficient of 0.16% at 1000°C, there is no need to consider the impact of thermal expansion on the structural stability of the furnace during actual use.

        The quartz brick boasts a silica content of 99.8% with low impurity levels of iron, calcium, and other elements. It exhibits a high softening temperature under load (above 1650°C) and high strength, with a compressive strength exceeding 50 MPa.
