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.

At high temperatures, the quartz tube will undergo a chemical reaction with alkali metals, resulting in the formation of crystallization. These crystalline regions exhibit increased fragility, leading to the development of cracks. Potential sources of alkali metal contamination may include the following.

Quartz glass plate is a common product of quartz crystal, which exhibits exceptional chemical and thermal stability, thereby rendering them suitable for utilization in a multitude of fields. The following outlines some of the most prevalent applications:

Quartz tubes are extensively utilized in the semiconductor industry, optical instruments, and laboratory equipment, often serving as critical components in precision instrumentation. To ensure optimal quality and performance of quartz tubes, it is necessary to carry out regular maintenance. The following are some suggestions for maintaining quartz tubes. In general, maintenance of quartz tubes...

By observing the density, hardness, transparency and other characteristics of the material, in conjunction with a series of testing methods, including the use of ultraviolet light, quartz glass can be accurately identify. At the same time, it is also important to be aware of certain types of glass that can be easily mistaken for quartz glass, in...

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.

The specific range of high-temperature tolerance is dependent on the purity of the quartz material, the manufacturing process, and the dimensions and shape of the crucible.
