| titleOfInvention | Preparation method and application of liquid silicon carbide ceramic precursor |
| abstract | The invention contains CH 2 Liquid silanes containing CH 2 -reacting a CH-bonded silane with an olefin metathesis reaction to obtain an intermediate product, said intermediate product containing CH 2 -CH-bonded silane having at least one Y attached to a silicon atom, said Y being reducible to a silicon-hydrogen bond; reducing the intermediate to obtain a compound containing-C-Si (H) a Radical or-C ═ C-Si (H) a The liquid silicon carbide ceramic precursor of group (a is a numerical value of 1, 2 and 3), the silicon-hydrogen bond in the liquid silicon carbide ceramic precursor is connected with group C-or-C-for supplying electron, so the activity of the silicon-hydrogen bond is higher, the silicon-hydrogen bond can be mutually dehydrogenated and polymerized, and can also be subjected to hydrosilylation, the liquid silicon carbide ceramic precursor can be self-crosslinked, and the ceramic yield at 1000 ℃ can reach 70-90%. |
