# 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.

## CVSIC Atmosphere Box Furnace Application
