Classification of impurities in quartz products in semiconductor technology
0 Comments
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.
Precautions and maintenance of quartz glass tubes in heating furnaces
0 Comments
It is imperative to maintain the furnace tube in a clean and hygienic state, ensuring that no substances capable of reacting with SiO2 are permitted to remain on the furnace tube. In order to extend the operational lifespan of the furnace tube, it is essential to employ the use of a quartz boat as...
