Quartz ingots are a key industrial raw material. They are widely used in electronics, optoelectronics, aerospace, and other fields. Quartz ingots have a high melting point and hardness. They are also very stable chemically. These qualities make them key in these fields.
Main uses of quartz ingots
Electronics:
Manufacturers use quartz ingots in transistors, capacitors, and sensors.
Optoelectronics manufacturers use quartz ingots in optical windows, lasers, LED packages, and CCD sensors.
Aerospace field:
Quartz ingots resist radiation well. Manufacturers use them in electronic components, optical instruments, and ceramic resonators.
Physical and chemical properties of quartz ingots.
High melting point:
The melting point of quartz ingots is as high as 1713℃, and they are not easy to decompose at high temperatures.
High hardness:
Quartz ingots have a hardness of 7. This gives them excellent physical properties.
Good chemical stability:
Quartz ingots are not corroded by acids or alkalis.
Application of quartz ingots in the semiconductor industry.
In semiconductor manufacturing, manufacturers use quartz ingots in several steps. These include diffusion, oxidation, deposition, and etching. We use quartz crucibles to refine and clean.
Quartz ingots and tubes are key for making diffusion, oxidation, deposition, and etching processes. Also, synthetic quartz ingots are the main substrate for photomasks in flat panel displays. As semiconductor technology has advanced, quartz products must perform better. They need low impurity and bubble content.
