Generally, the quality of quartz plates depends on multiple factors, including purity, crystallinity, appearance, and physical properties. Only when these aspects meet the required standards can the quartz plate be considered a high-quality product, making it more suitable for various applications and needs. Therefore, during the production and processing stages, it is essential to...

Various impurities are unavoidably introduced during the preparation process of quartz glass, which gives rise to the occurrence of defects in quartz glass and the alteration of its properties. Common defects in quartz glass can be classified into two categories: structural defects and macroscopic defects.

The quartz glass product exhibits a multitude of advantageous characteristics, including high transparency, high temperature resistance, corrosion resistance, high purity and favourable electrical insulation properties. However, it should be noted that quartz glass also has certain disadvantages, including brittleness, processing difficulty, susceptibility to scratches and sensitivity to ultraviolet light. 

Manufacturers of quartz products typically classify impurities based on the specific application environments. This classification of impurities can be broadly categorized into several types: visible impurities (such as bubbles, gas lines, color spots, and nodules), heavy metals, alkali metals, and hydroxyl groups.

The production of quartz boats requires careful consideration of several key aspects, including the selection of raw materials, grinding, mold design and manufacturing, vacuum adsorption, sintering, surface treatment, product testing and quality control.

Quartz glass exhibits a range of excellent optical properties. Compared with ordinary glass, high-purity quartz glass has good transmittance across an extensive range of wavelengths, from the far ultraviolet (160nm) to the far infrared (5μm), which is not available in general optical glass. The excellent spectral transmittance and optical uniformity make quartz glass widely used...

The preparation of quartz glass can be divided into two main categories. The first type refers that the quartz glass is obtained by melting natural quartz crystal or silica as raw materials, which is called natural quartz glass. According to the different heat sources and processes, the methods of the first type can be...
