Pressureless Sintered Silicon Carbide Saggers

Pressureless Sintered Silicon Carbide (SSiC) Saggers are advanced kiln furniture products manufactured through pressureless sintering technology. With excellent density, mechanical strength, thermal conductivity, and corrosion resistance, these saggers provide reliable performance in high-temperature firing environments.

Featuring a density of 3.06-3.16g/cm³ and an apparent porosity of less than 0.1%, pressureless sintered silicon carbide saggers offer excellent structural integrity and gas tightness. The high bending strength of 400-700MPa ensures outstanding load-bearing capability during repeated thermal cycles, while thermal conductivity above 100W/(m·K) enables efficient heat transfer and uniform temperature distribution.

These high-performance SiC saggers are widely used for firing electronic components, powder metallurgy products, advanced ceramics, refractory materials, and calcination processes involving rare metals and loose materials.
