Silicon nitride (Si3N4) exhibits moderate thermal conductivity, typically ranging from 15-30 W/m·K, depending on its purity and microstructure. While lower than metals like aluminum, its thermal conductivity is superior to many other ceramics, making it ideal for applications requiring heat dissipation and thermal shock resistance, such as in aerospace and automotive components.
The price of silicon nitride plate varies according to specifications, quantity, and performance requirements. Please provide specific size, quantity, and technical requirements (with drawings preferred), and we will give you an estimate.
Silicon nitride plates require diamond grinding tools or laser cutting due to their extreme hardness. Precision machining techniques, such as CNC grinding, ensure tight tolerances and smooth finishes. Proper cooling and skilled handling prevent cracking.
Silicon nitride plates exhibit exceptional hardness (Vickers hardness ~1500-1800 HV), surpassing many metals and ceramics. This high hardness ensures superior wear resistance and durability in harsh environments.
