Silicon carbide (SiC) rollers, especially pressureless sintered SiC (SSiC) rollers for lithium battery kilns, are widely used in cathode material production due to their high-temperature stability and mechanical strength. However, under different process conditions, their corrosion behavior can vary ...
-
Background A chemical equipment manufacturer required a material solution for components operating in both acidic and alkaline environments. The application involved: Strong acids (e.g., H₂SO₄, HCl) Alkaline media (e.g., NaOH solutions) Operating temperatures up to 100°C Continuous immersion ...

Client Challenge The German furnace manufacturer faced critical limitations with traditional refractory materials in their high-temperature furnaces (1500°C+): Structural Instability: Alumina-silicate beams showed creep deformation after 500 hours of operation, leading to furnace misalignment and ...
-
Client Challenge The Swiss institute faced critical limitations with conventional alumina and graphite saggers in their ultra-high-purity ceramic sintering processes (1700°C+): Contamination Risks: Alumina saggers leached alkaline ions into ceramic powders, compromising material purity for aerospace ...
