Manufactured from high purity quartz with integral precision processing, it delivers 1100°C heat resistance, superior HF and acid/alkali chemical durability for high temperature sintering, wet chemical processing and semiconductor material purification applications.

Product Parameters

Key Features

• Uniform 5mm Thick Wall – Precision processed with consistent wall thickness throughout, providing structural strength and thermal uniformity for high temperature applications.
• 1100°C Heat Resistance – Maintains dimensional stability and structural integrity at continuous high temperatures without deformation or cracking, ideal for sintering processes.
• HF & Strong Acid Resistance – Superior chemical durability against hydrofluoric acid and concentrated strong acids and alkalis, unmatched by borosilicate glass alternatives.
• High Purity, No Contamination – 99.99% pure quartz ensures no impurity precipitation that could contaminate sensitive materials during processing.
• Excellent Thermal Shock Resistance – Withstands rapid temperature changes without cracking, enabling safe quenching and heating cycles in laboratory and production environments.

Applications

1. High Temperature Sintering

Square tank for powder material sintering and high-temperature solid-state reactions in laboratory and pilot-scale production, withstanding sustained 1100°C operation.

2. Wet Chemical Pickling

Open square vessel for wet acid pickling and corrosion sample immersion testing, resistant to HF and strong acid solutions that would attack borosilicate glass containers.

3. Semiconductor Material Processing

Small-batch raw material purification reaction tank for semiconductor manufacturing, providing contamination-free containment for high-purity chemical processes.

4. Coating Equipment Fixture

Internal positioning cavity and tooling sleeve for coating equipment, offering dimensional stability and chemical inertness in vacuum deposition environments.

Advantages over Borosilicate Glass

Unlike borosilicate glass containers that are attacked by hydrofluoric acid and risk cracking under thermal stress, this quartz container offers superior HF resistance, 1100°C thermal stability without deformation, and high purity that prevents material contamination—making it the essential choice for demanding chemical, semiconductor and high-temperature processing applications.
