Silicon Nitride Crucible Description

Silicon Nitride Crucible is a high-efficiency container crafted from silicon nitride, a man-made ceramic celebrated for its remarkable characteristics, including immense strength, durability, and resistance to thermal shock. Created through gas pressure sintering, this crucible exhibits excellent resilience against both acidic and mild alkaline corrosion. It finds its application in challenging conditions that involve extreme heat, corrosive surroundings, or swift shifts in temperature.
