Atmosphere Box Furnace

The CVSIC Box-Type Atmosphere Furnace is a high-performance thermal processing solution designed for precision heat treatment in controlled atmospheres. With a maximum temperature of 1700°C, this furnace supports inert gases (N₂, Ar, CO₂) and pre-vacuuming up to -0.08 MPa, creating an ultra-pure environment for sintering, annealing, and diffusion processes.

Equipped with high-purity alumina fiber insulation, intelligent PID temperature control, and robust chamber construction, it is widely adopted in material laboratories, semiconductor manufacturing, and pilot-scale production of silicon nitride ceramics, composites, and photovoltaic materials.

CVSIC Atmosphere Box Furnace Features

• Wide Temperature Range: Available in 1200°C / 1400°C / 1700°C models to meet diverse processing needs.
• High-Precision Control: Industrial-grade 0.2-class controller, PID algorithm, 50-step programmable profile, ±1°C accuracy.
• Vacuum & Inert Atmosphere: Pre-vacuum up to -0.08 MPa, supports N₂ / Ar / CO₂ gas injection to prevent oxidation and contamination.
• Advanced Chamber Design: Alumina polycrystalline fiber with low thermal conductivity and chemical stability for uniform heating.
• Reinforced Structure: 12mm solid square steel ribs and double-thick steel plates prevent deformation during vacuum operation.
• Superior Sealing: Four-handwheel door lock and silicone sealing ring ensure atmosphere containment and operational safety
• Flexible Heating Options: Choose from resistance wire, SiC rods, or MoSi₂ rods depending on process temperature and materials.
• Included Accessories: Fire bricks (except 1200°C), gloves, tongs, vacuum pump, spares—ready for operation out of the box.
