Cordierite ceramic part refractory mullite ceramic part
Features & Advantages
1. High hardness.
2. High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.
4. High electrical resistivity: alumina is an electrically insulating material.
5. High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
Cordierite ceramic
Cordierite ceramic is one of the most popular ceramics for its properties of excellent thermal stability, high refractoriness, good chemical durability, low dielectric constant, and low thermal expansion.
