What Are the Advantages and Disadvantages of Silicon Carbide?​​

​​Aspect​​
​​Advantages​​
​​Disadvantages​​
​​Hardness​​
​​Mohs 9.5 (second only to diamond)​​ → Excellent for abrasives & wear resistance.
​​Difficult to machine & shape​​.
​​Thermal Conductivity​​
​​High (490 W/m·K)​​ → Efficient heat dissipation in electronics & refractories.
​​Brittle (can crack under impact)​​.
​​Thermal Shock Resistance​​
​​Withstands rapid temperature changes​​ → Ideal for furnaces & molten metal handling.
​​Not as flexible as metals​​.
​​Chemical Resistance​​
​​Resistant to acids, alkalis, and molten salts​​ → Used in harsh environments.
​​Can react with strong bases at high temps​​.
​​Electrical Properties​​
​​Wide bandgap semiconductor (3.3 eV)​​ → High-voltage, high-temperature electronics.
​​Requires specialized manufacturing​​.
​​Cost​​
​​Cheaper than diamond but more expensive than alumina​​.
​​High-purity SiC is costly​​.
