Introduction
Sagger RSiC Acid And Alkali Resistant Alumina Coating
Introduction of RSiC sagger
The core advantages of RSiC sagger
(1) Ultra high temperature stability
Temperature endurance limit: Long term endurance of 1650 ° C, far exceeding the aluminum oxide sagger (1600 ° C) and graphite sagger.
Case: When firing ZrB. – SiC ultra-high temperature ceramics, the lifespan of the RSiC sagger is more than three times that of graphite.
(2) Chemical inertness
Corrosion resistance: Resistant to the erosion of molten borides and hydrides (such as AI vapor in AIN sintering), its stability in HF/HCI atmosphere is better than that of alumina sagger.
Case: When firing fluoride transparent ceramics (such as CaF), there is no risk of oxidation reaction in the RSiC sagger.
(3) Uniformity of thermal field
Porous structure (15-20% porosity): promotes uniform infiltration of atmosphere and avoids density differences in the same part of ceramics;
Pores can serve as a thermal buffer layer, reducing thermal stress (crucial for large ceramic components)
(4) Low pollution
Purity>99.999%: Avoid impurities such as Fe and AI from migrating into the ceramic, which may affect the dielectric/mechanical properties.
