In photovoltaic and semiconductor crystal pulling processes, quartz crucibles are typically classified as single-use core consumables. Due to physicochemical changes such as high-temperature crystallization, chemical erosion, and thermal stress, conventional quartz crucibles must be discarded after

As a high-purity silicon dioxide (SiO2) material, quartz rods typically have a bending strength between 50 MPa and 65 MPa, and some fiber grade quartz rods that have undergone special processing can even have a flexural strength of over 200 MPa. Although quartz material is essentially a brittle cera

precision requirements are extremely high. As the core component of optical communication connectors, the dimensional accuracy and concentricity of optical fiber cores directly affect the transmission efficiency and loss of optical signals. Typically, the outer diameter tolerance of a quartz ferrule
