■ Introduction:
Corundum ceramic sagger is a type of ceramic container used for high temperature processing of materials such as metals, ceramics, and chemicals. Made of high purity alumina or zirconia, alumina corundum sagger are highly resistant to thermal shock and chemical corrosion. The refractory corundum ceramic sagger are designed to withstand temperatures up to 1800°C and provide a stable environment for processing materials in a furnace or kiln.
Corundum ceramic saggers are commonly used in the production of advanced ceramics, electronic components, and refractory materials. The high alumina ceramic saggers are also used in the manufacturing of powder metallurgy products, such as tungsten carbide and diamond cutting tools.
The advantage of using corundum ceramic saggers is that they provide a clean and contaminant-free environment for processing materials. They are also durable and long-lasting, which makes them cost-effective in the long run.
