一般说,硅氮键对水不稳定,因此聚硅氨烷尽管具有较好的耐热性,但是仍未得到应用。等指出,硅原子或氮原子上带有较大的空间位阻的基团后,如苯基等,可以提高硅氨烷的水解稳定性,取代基的电子效应对其水解稳定性也有影响。Fink发现 In general, silicon nitrogen bonds are not stable to water, so polysilazane has not been used in spite of its good heat resistance. Pointed out that the silicon atom or nitrogen atoms with a larger steric hindrance of the group, such as phenyl and so on, can improve the hydrolyzable stability of silazane, substituent electronic effects on its hydrolytic stability. Fink found
