Quartz Crucible Supplier

Quartz Crucible is a high-temperature container made of high-purity quartz sand. It is widely used in photovoltaics, semiconductors, metal smelting and laboratory research. As a representative product of Chinese Quartz Crucible manufacturers, our Quartz Crucible is made of advanced melting technology and has excellent characteristics such as ultra-high purity, high temperature resistance, thermal shock resistance and strong chemical stability. It is an ideal choice for single crystal silicon growth, precious metal smelting and high-temperature experiments.

According to the application scenarios and performance requirements, Quartz Crucibles are mainly divided into photovoltaic grade, semiconductor grade, opaque melting type, special melting type, laboratory type and sintered quartz glass type.

Photovoltaic grade Quartz Crucible is mainly used for the drawing of single crystal silicon rods. It is the core consumable of single crystal furnace in the photovoltaic industry chain. It has high purity and high temperature resistance. It can withstand high temperature of 1450℃ for a short time. Semiconductor grade Quartz Crucible is used for the growth of high-purity single crystal silicon in the semiconductor industry. It has higher purity and stronger thermal stability, which fully complies with SEMI international certification standards.

Opaque fused Quartz Crucibles are made by special process, with higher thermal shock resistance and corrosion resistance, especially suitable for environments with drastic temperature changes. Crucibles for melting gold are specially designed for the smelting of precious metals such as gold and silver. They can withstand high temperatures above 1600℃ and effectively resist metal erosion.

Laboratory Quartz Crucibles are mainly used for high-temperature experiments in scientific research institutions and universities, with high cleanliness and acid and alkali corrosion resistance. Sintered quartz glass crucibles are suitable for long-term high-temperature sintering processes. The structure is enhanced by special sintering processes, which greatly extends the service life.

The core performance of Quartz Crucibles is mainly reflected in five aspects: first, ultra-high purity, with SiO₂ content as low as 99.99%; second, excellent high temperature resistance, with the highest continuous use temperature of 1100℃ and short-term tolerance of 1450℃; third, excellent thermal shock resistance, which can withstand rapid temperature rise and fall; fourth, stable chemical properties, acid and alkali corrosion resistance (except hydrofluoric acid); finally, extremely low thermal expansion coefficient, ensuring dimensional stability at high temperature. These characteristics make it an irreplaceable key material in high-temperature industry.

As a professional Quartz Crucible manufacturer, we use strict manufacturing processes to ensure product quality. Starting from the selection of high-purity quartz sand, it goes through multiple processes such as arc melting and precision machining, and finally passes strict quality inspection procedures such as X-ray detection and spectral analysis. The entire production process is carried out in a vacuum or inert gas environment to ensure that the product is pollution-free. We can also provide customized services of different sizes and shapes according to customer needs.

Quartz Crucibles are widely used in many important industries. In the photovoltaic industry, it is a key consumable for single crystal silicon pulling; in the semiconductor field, it is used to manufacture silicon wafers; in the metal smelting industry, it is an essential tool for precious metal smelting; in the scientific research field, it supports various high-temperature experiments; in the manufacture of special glass, it plays an irreplaceable role. With the rapid development of industries such as photovoltaics, semiconductors, 5G communications and new energy, the market demand for high-purity Quartz Crucibles is continuing to grow.

As a leading Chinese Quartz Crucible manufacturer, we have three core advantages: strictly controlled high-purity raw materials, advanced production processes of international standards, and a complete quality inspection system. We are fully aware of the importance of Quartz Crucibles to our customers' production processes, so we always adhere to the highest standards to ensure that every product reaches 100% pass rate.
