Surface Chemistry Analysis of Si3N4 Powders and Selection of the Dosage of Coupling Agents
Si3N4粉体表面分析及偶联剂作用量的选择

Oxidation and hydrolization are disadvantageous factors in producing and storing Si3N4 powders. But it provides a convenience in the aspect improving the compatibility between inorganic ceramic powders and organic medium. In this article, the surface characters of as-received and modified powders were compared and their effect on the selection of coupling agents was also discussed.
