Advanced Atmosphere Furnace – 1700°C, Vacuum & Inert Gas Ready | Jiuying
I’m David from Jiuying, and I’ve worked with laboratory managers and production engineers who need precise, contamination-free heat treatment. Our Atmosphere Furnace (model JY-17AM-8) combines high-temperature capability up to 1700°C with a built-in vacuum pump and inert gas system. Whether you’re sintering ceramics, annealing metals under argon, or performing protective atmosphere heat treatment, this furnace eliminates oxidation and gives you repeatable results. Let me walk you through why this Atmosphere Furnace has become a favorite among R&D labs and small-batch production lines.
How This Atmosphere Furnace Works – Working Principle
Unlike a standard box furnace, our Atmosphere Furnace integrates a vacuum pump and gas inlet/outlet valves. First, you place your samples inside the 200x200x200mm chamber and seal the door. The vacuum pump evacuates air to a maximum vacuum of -0.08MPa, removing oxygen and moisture. Then you backfill with inert gas (nitrogen or argon) to create a protective environment. The PID controller via SCR power control ramps temperature up to 1600°C continuously (or 1700°C for short periods) at rates of 0-15°C/min. The U-type MoSi2 heating elements and three-layer ceramic fiber insulation (up to 1800°C grade) ensure excellent thermal stability and minimal thermal loss – all while keeping the outer shell below 60°C.
Key Performance Features
Vacuum + Atmosphere Ready: Achieve -0.08MPa vacuum, then purge with N2 or Ar. Prevents oxidation, decarburization, and surface scaling – critical for high-purity material processing.
Large 7-Inch Touch Screen: Real-time heating curve display, 30 programmable segments (heating, cooling, dwelling). One-click automatic cycle completion, no attendant needed.
High-Temperature Accuracy: B-type thermocouple (Pt-Rh) with 99.7% alumina protection tube, accuracy ±1°C.
Robust Safety: Over-temperature protection, broken thermocouple detection, automatic power cut-off if door opens.
Low Surface Temp: Double steel casing + dual cooling fans keep exterior below 60°C, safe for lab benches.
Product Details – Built for Precision & Durability
Let me share what you’ll actually get with our Atmosphere Furnace. The chamber uses three layers of ceramic fiber board: 1800°C inner layer, 1600°C middle layer, and 1430°C outer layer – this cascade design reduces heat loss by nearly 30% compared to standard two-layer furnaces. The heating elements are high-density U-type MoSi2, which can withstand rapid heating without cracking. Every unit includes one vacuum pump, one vacuum gauge, gas inlet/outlet ports, a pair of high-temperature gloves, a crucible clip, and an English manual. One small note: over extended use, slight cracks may appear on refractory ceramics – this is normal and can be repaired with alumina coating. Also, always insert the refractory door block before closing the door.
Application Scenarios – Where This Atmosphere Furnace Excels
Our clients use this furnace for:
High-temperature sintering of advanced ceramics (Al2O3, ZrO2) under argon.
Annealing of metals and alloys without oxidation (stainless steel, titanium, copper).
Heat treatment of precious metals or powder metallurgy parts.
Research labs requiring controlled atmosphere for material synthesis.
Small-batch production of special alloys where surface purity is critical.

How It Differs from Conventional High-Temperature Muffle Furnaces
Many standard furnaces claim high temperatures but lack vacuum or atmosphere capability – meaning your parts will oxidize above 600°C. Our Atmosphere Furnace includes a rotary vane vacuum pump and gas flow system, so you can purge oxygen completely. Additionally, the 7-inch touch screen with real-time curve logging is rare at this price point. Competitors often hide cooling rate limits or use inferior insulation that cracks rapidly; our three-layer fiber board and explicit cooling rate limit (≤10°C/min) prolong the lifespan of the chamber. And the one-year warranty on non-consumable parts gives you confidence that we stand behind our engineering.

Frequently Asked Questions (FAQ) – Atmosphere Furnace
A: No – the warranty explicitly excludes damage from corrosive or acidic gases. For such applications, you would need a special alloy retort and ventilation system. Contact us for customization.
A: The included rotary vane pump needs oil changes every 100-200 operating hours. We provide detailed instructions in the manual.
A: Yes – the 30-segment program allows you to define heating rate, dwell time, and cooling rate. You can also add intermediate soaking steps.
A: Absolutely. Standard options go up to 300x300x400mm or custom dimensions. Please provide your required volume and we’ll quote accordingly.
A: With natural cooling (door closed and no forced gas), it takes about 3-4 hours. Using the recommended cooling rate ≤10°C/min, you can program a controlled descent to avoid thermal shock.
