Quartz crucibles are containers made of high purity fused quartz or fused quartz glass, used for high-temperature applications, especially in the manufacture of semiconductor wafers. They are designed to withstand extreme temperatures and thermal shock, making them ideal for high-temperature applications.
Quartz crucibles are containers made of high purity fused quartz or fused quartz glass, used for high-temperature applications, especially in the manufacture of semiconductor wafers. They are designed to withstand extreme temperatures and thermal shock, making them ideal for high-temperature applications.
Quartz crucibles are commonly used in the production of semiconductor wafers, to hold and melt semiconductor materials such as silicon or gallium arsenide. They are also used in the production of LEDs, solar cells, and other electronic components that require high-purity materials.
Quartz crucibles are known for their excellent thermal stability and resistance to thermal shock, which allows them to be used in applications that require high temperatures and rapid temperature changes. They also have strong resistance to chemical corrosion, making them ideal for use in corrosive environments.
Quartz crucibles can be manufactured in a variety of shapes and sizes to meet the needs of different applications. They can be used in batch and continuous processes and can be reused multiple times with proper cleaning and maintenance.
Overall, quartz crucibles are an important tool for the production of high-purity materials used in electronic and semiconductor applications. Their unique properties make them ideal for applications that require high-temperature stability, heat resistance, and chemical resistance. Quartz crucibles are the amorphous form of silicon dioxide (SiO2). Their highly cross-linked three-dimensional structure gives them high operating temperatures and low thermal expansion coefficients. Quartz crucibles come in two forms: milky white and translucent. Milky white quartz is crystalline quartz, which appears white, translucent to nearly opaque due to the presence of uniformly distributed gas and/or fluid inclusions. Due to their high purity and excellent chemical resistance, quartz crucibles can also be used in other industrial applications such as glass melting, chemical processing, and powder sintering.
