Silicon Nitride Ceramic Diamond Blocksmerits

The advantages of silicon nitride ceramic rhombic blocks lie firstly in the high strength and excellent anti-chipping performance. The sharp corners and beveled edges of rhombic blocks are prone to local stress concentration during assembly, compression and stress, and ordinary materials are prone to chipping and edge wear, while silicon nitride ceramics, with its extremely high flexural strength and excellent fracture toughness, can keep the corners intact for a long time to ensure positioning and guiding accuracy. It has excellent wear resistance and bevel stability. Silicon nitride ceramic diamond block is commonly used in bevel compression, guide slip and wedge positioning structure, silicon nitride ceramic high hardness surface can effectively resist long-term friction abrasion, to ensure that the bevel angle and contact surface flatness long-term stability.

Advantages of Silicon Nitride Ceramic Diamond Blocks

The high flexural strength of silicon nitride ceramics ensures that the diamond-shaped corners do not chip under long-term loads, and the high hardness significantly reduces the frictional wear rate of the beveled surfaces. Compared to repetitive pressing and sliding mechanisms in automated equipment, the angle consistency and contact surface accuracy can be maintained over a long period of time. The extremely low coefficient of thermal expansion of silicon nitride ceramics allows them to maintain dimensional stability in high-temperature fixtures and heat-treating fixtures, preventing thermal errors from affecting clamping effectiveness. For semiconductor equipment, it also avoids contamination by metal particles and improves system cleanliness and reliability.

High strength and not easy to chip
Long wear life
Excellent high temperature resistance
