Description:

The pressureless sintered silicon carbide (SIC) saggers can adopt three different forming processes depending on product specifications: isostatic pressing, slip casting and dry pressing. The formed green bodies undergo preliminary processing before being sintered at high temperatures in a pressureless vacuum sintering furnace.

Typical application:

Saggers are primarily used in kiln heat treatment processes, providing product transportation and protection during high-temperature firing.

Application Fields: Electronics & Semiconductor;  Automotive; Glass & Photovoltaic; Lithium Battery Cathode Powder Production;  other industrial sectors' sintering processes.

Feature:

1.High Mechanical Strength – Ensures durability under high loads.  

2.Exceptional High-Temperature Resistance – Withstands extreme heat without degradation.  

3.Superior Thermal Stability– Maintains structural integrity under prolonged thermal cycling.  

4.Excellent Corrosion Resistance– Resists chemical erosion in harsh environments.  

5.Customizable Designs– Tailored to meet specific application requirements.  

6.Extended Service Life– Delivers stable and long-lasting performance,reducing replacement frequency.

Material Comparison

Key Advantages:

Pressureless Sintered SiC (SSiC): Superior overall performance for high-temperature, corrosive, and high-stress environments

Alumina(Al₂O₃) : High-temperature resistance up to 1800°C, but poor thermal shock resistance

Graphite: Excellent thermal conductivity, but requires inert atmosphere protection

Reaction-Bonded SiC (RB-SiC): Cost-effective alternative, but lower density and corrosion resistance vs. SSiC

Recommendations: 

Priority Choice(SSiC): Ideal for Li-ion battery sintering, semiconductor wafers, metal purification

Alternative solution(RB-SiC): Cost-effective solution for temperatures below 1380°C

Alumina (Al₂O₃): Suitable for non-thermal-shock applications
