Quartz crucibles are ceramic crucibles made from high-purity fused silica, offering excellent thermal shock resistance and high-temperature performance. They are mainly used in high-temperature melting and chemical reactions, especially in the preparation of polycrystalline and single-crystal silicon. Quartz materials have low thermal conductivity, a small coefficient of thermal expansion, and good mechanical and chemical stability.

Key Features

• Excellent Thermal Shock Resistance: Can withstand rapid temperature changes, preventing damage from thermal shock.
• High-Temperature Stability: Does not easily deform in high-temperature environments, making it ideal for high-temperature melting.
• Low Coefficient of Thermal Expansion: Near-zero thermal expansion minimizes stress and deformation at high temperatures.
• Chemical Corrosion Resistance: Provides good chemical stability, suitable for various chemical environments.
• Good Mechanical Properties: Maintains good compressive and bending strength under high-temperature conditions.

Applications

• Non-Ferrous Metal Smelting: Used for melting and refining metals and alloys.
• Chemical Industry: Used for calcining high-purity materials and handling acidic substances.
• Pharmaceutical and Food Industry: Suitable for processing pharmaceuticals and food products.
• Environmental Engineering: Used in high-temperature experiments and material processing.
• Biotechnology: Applied in certain biological reactions and experiments.
• Aerospace: Widely used in precision material processing and equipment manufacturing.
