The Uses of Quartz Ingot

Quartz ingots are a key industrial raw material. They have extensive applications in electronics, optoelectronics, and aerospace. Quartz ingots have a high melting point, high hardness, and good chemical stability. These traits make them key in these fields.

The Main Uses of Quartz Ingots

Electronics: Quartz ingots are the main material in electronic parts. They are widely used in transistors, FETs, capacitors, ceramic resonators, and ultrasonic sensors.

Optoelectronics: Quartz ingots are in optical windows, lasers, LED packages, and CCD sensors.

Aerospace field: Quartz ingots have high radiation resistance. Manufacturers use them in electronic components, optical instruments, and ceramic resonators.

The Physical and Chemical Properties of Quartz Ingots

High melting point: Quartz ingots melt at 1713℃. They do not easily decompose at high temperatures.

High hardness: Quartz ingots have a hardness of 7. This gives them excellent properties.

Good chemical stability: Quartz ingots are not corroded by acids or alkalis.

The Application of Quartz Ingots in the Semiconductor Industry

In semiconductor manufacturing, manufacturers use quartz ingots in several processes. These include diffusion, oxidation, deposition, and etching. Refiners use quartz crucibles to clean and refine materials. Quartz ingots and tubes are vital for diffusion, oxidation, deposition, and etching. Also, synthetic quartz ingots are the main substrate for photomasks in flat-panel displays. As semiconductor technology has advanced, the demand for quartz products has risen. They now must low impurity and bubble content.
