| titleOfInvention | A kind of method improving SiC filed emission cathode material high-temperature electronic launch stability |
| abstract | A kind of method improving SiC filed emission cathode material high-temperature electronic launch stability, it includes step in detail below: 1) the poly-silicon boron azane of organic precursor is incubated the solidification of 30min heat cross-linking, then ball mill pulverizing in 260 DEG C in atmosphere sintering furnace；2) with carbon paper for substrate, at the Co (NO of 0.05 mol/L 3 ) 2 Impregnation process in (purity: 99%) alcoholic solution, takes out nature and dries standby；3) being placed in bottom graphite crucible by pulverizing the powder obtained, the carbon paper of impregnation process is placed in graphite crucible top, is placed in together in atmosphere protection stove；4) under the Ar atmosphere protection that purity is 99.9%, heat to 1550 DEG C from room temperature with 25 DEG C/min；5) it is cooled to 1100 DEG C with 15 DEG C/min from 1550 DEG C；6) room temperature is cooled to the furnace, it is achieved the preparation of original position B doping SiC nanowire；7) SiC nanowire is used as field-transmitting cathode and carries out electron emission capability detection and analysis.Being adulterated by B, the high-temperature electronic launch stability of SiC filed emission cathode material obtains and is effectively improved. |
