A rather complex surface structure including amino-, hydroxy- and silanol-groups, adsorbed CO2 and a complex surface compound consisting of Si, N, C and H was proposed for the laser synthesized Si3N4 powders subjected to atmospheric ageing.

In order to preserve the structure of the nucleation layer, a quite low growth temperature of approximately 1200°C was chosen.
Physical Chemistry.

Being free from the electricity and chemistry performance of material, ultrasonic machining has special significance to the brittle and nonconducting engineering ceramics material.
The structure has gone through interference examining in the process of assembling and both the physical design and the dimension proved reasonable.
