FAQ
Q: How does the sintered density of sintered mullite affect its service life?
A: High sintered density increases material strength and resistance to slag erosion, extending the service life of furnace linings and refractory bricks.
Q: Why does sintered mullite have better thermal shock resistance than ordinary refractory bricks?
A: The needle-shaped crystal structure formed during the sintering process reduces thermal expansion stress, significantly improving thermal shock cracking resistance.
Q: How does improper storage affect the performance of sintered mullite?
A: Moisture or mechanical damage can cause structural damage, affecting refractory properties and operational stability.
Q: What specific applications are suitable for sintered mullite of different particle sizes?
A: Fine particle sizes are suitable for precision casting and ceramic blanks, while coarse particle sizes are more suitable for furnace lining refractory brick manufacturing.
Q: What is the chemical resistance of sintered mullite in high-temperature corrosive environments?
A: The sintering process improves its chemical stability, making it resistant to corrosion from a variety of high-temperature molten slags and acidic gases.
