| titleOfInvention | Method for efficiently preparing compact SiBCN ceramic by modifying polyborosilazane with free radical initiator |
| abstract | The invention relates to a method for efficiently preparing compact SiBCN ceramic by using radical initiator modified polyborosilazane, which comprises the following steps: under the protection of inert atmosphere, mixing liquid polyborosilazane containing vinyl functional groups and a free radical initiator, and then crosslinking and curing for 0.5-2 hours at 50-150 ℃ to obtain a transparent solid, wherein the free radical initiator is a peroxy initiator or/and an azo initiator; and (3) carrying out heat treatment on the obtained transparent solid for 2-4 hours at 900-1400 ℃ in an inert atmosphere to obtain the compact SiBCN ceramic. According to the invention, the polyborosilazane is modified by using the free radical initiator, and the ceramic yield is improved from about 17% to about 74%. |
