A high-temperature sintering furnace is a type of special chemical equipment used to sinter materials at elevated temperatures. Raw materials are heated to a required temperature to induce chemical reactions or physical changes. High-temperature sintering equipment can be classified into five categories:
- Aluminum nitride (AlN) ceramic sintering furnace
- Tungsten carbide vacuum sintering furnace
- Vacuum debinding and sintering furnace
- Silicon carbide pressureless sintering furnace
- Tantalum–niobium metal product sintering furnace
Each has unique applications and characteristics. Today, the manufacturer will introduce the aluminum nitride ceramic sintering furnace.
Applications of Aluminum Nitride Ceramic Sintering Furnace
The AlN ceramic sintering furnace is suitable for temperatures between 1600°C and 2000°C, operating under slight positive pressure or in a controlled atmosphere.
It is commonly used for sintering green bodies formed from aluminum nitride powder and metal sintering aids.
For pressureless sintering of AlN ceramics, a high temperature is required. Increasing the sintering temperature and extending the holding time helps improve the density of the aluminum nitride ceramic.
Features of Aluminum Nitride Ceramic Sintering Furnace
- Longer holding time is required to complete densification
- The equipment and process are relatively simple and easy to operate
- During heating, the powder particle aggregate transforms into a crystalline bonded structure
- Pressureless sintering is the simplest and most widely used method
- Typical sintering temperature range: 1600°C–2000°C
