在Si3N4粉体的生产和存储过程中,氧化和水解是两个不利的因素,但在偶联剂的作用下,它们在提高陶瓷粉体与有机载体的相容性方面起到了促进作用.本文测定了未经处理的Si3N4。粉及通过氧化和水解改性的Si3N4粉的表面性质,并分析了它们对偶联剂选择作用量的影响.
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.
