People who have not been in contact with quartz crucibles do not understand the function of single crystal silicon. Below, we will introduce the specific requirements of single crystal silicon for quartz crucibles:
The geometric dimensions and appearance of quartz crucibles depend on the production process, while the purity is determined by the raw materials. The raw materials for quartz crucibles require high purity, good consistency, and uniform particle size distribution. Only with good quality of raw materials can the quality of quartz crucibles produced be guaranteed.
When the content of harmful elements is high, it will affect the temperature resistance of the quartz crucible, causing bubbles, stains, peeling and other phenomena, seriously affecting the quality of the quartz crucible. The total content of harmful elements is high, and defects such as bubbles and white spots will appear, leading to a decrease in the transparency of the quartz crucible
A quartz crucible is a consumable container for drawing single crystal silicon. For every furnace of single crystal silicon produced, one furnace is consumed. Because monocrystalline silicon is the raw material for producing large-scale integrated circuits, the requirements for quartz crucibles are relatively strict.
