Introduction to Quartz Ceramic Products

Quartz ceramic, also known as fused quartz ceramic or pure silicon ceramic, is an advanced ceramic material made of pure silicon dioxide (SiO₂). It is made by melting high-purity quartz sand at high temperature and then cooling and solidifying it. It has unique physical and chemical properties, making it an ideal choice for many high-tech applications. Quartz ceramic products are widely used in semiconductor manufacturing, optics, electronics, chemical industry and high-temperature industries.

Characteristics and advantages of quartz ceramics

Extremely high thermal stability: Quartz ceramics can remain stable under extreme temperature conditions. They are not only resistant to high temperatures, but also show excellent thermal shock resistance in rapid temperature changes.

Low thermal expansion coefficient: Due to its low thermal expansion coefficient, quartz ceramics have good dimensional stability when the temperature changes and are not easy to deform or crack.

Excellent electrical insulation: Provides excellent electrical insulation performance and is suitable for applications requiring high voltage isolation.

High transparency: It has good light transmittance in a wide band from ultraviolet to infrared, and is particularly suitable for applications such as optical windows and lenses.

Chemical stability: Excellent resistance to most acids, alkalis and other corrosive substances, and almost unaffected by other chemicals except hydrofluoric acid and phosphoric acid.

Mechanical strength: Although quartz ceramic is not as hard as some other types of ceramics, it still has enough mechanical strength to meet the needs of many application scenarios.

High UV transmittance: It has high transmittance in the ultraviolet region, which makes it very useful in UV curing equipment and UV spectrometers.

5 FAQs of Inert Gas Nitrogen / Argon Quartz / Alumina Ceramic Tube Atmosphere Furnace

What is an inert gas atmosphere furnace used for? The furnace creates a controlled environment for heating materials without exposing them to air. This is crucial for processes needing no oxygen or moisture. It works with metals, ceramics, or chemicals. The inert gases like nitrogen or argon replace the air inside the chamber. This stops oxidation or contamination during high-temperature steps.

Why use nitrogen or argon in the furnace? These gases are chemically inactive. They do not react with most materials even at high heat. Nitrogen is cheaper and suits general applications. Argon is heavier and better for preventing reactions in sensitive materials. Both gases keep the furnace environment stable. They protect samples from unwanted chemical changes during heating.

What is the difference between quartz and alumina ceramic tubes? Quartz tubes handle temperatures up to 1200°C. They are transparent and work well for visible monitoring. Alumina tubes withstand higher heat, up to 1800°C. They are stronger and resist thermal shock better. The choice depends on temperature needs and material compatibility. Quartz is ideal for moderate heat. Alumina suits extreme temperatures.

What temperature range does this furnace cover? Models vary. Standard units reach 1200°C with quartz tubes. High-temperature versions using alumina go up to 1800°C. The range depends on heating elements and insulation. Users must check specs for their specific needs. Consistent temperature control ensures reliable results. Overheating beyond tube limits causes damage.

What safety features are included? The furnace has automatic shut-off for overheating or gas leaks. Alarms alert users to pressure drops or gas flow issues. Tubes are designed to handle thermal stress. Protective casings prevent external heat exposure. Proper ventilation is required to manage gas exhaust. Regular maintenance checks ensure safe operation.
