Abstract:
The exper im ent show s that VO2 phrase transition po ints of CTR( Cr itica lTemperature Resister) samp les produced by Vanadium ox ide doped in d iffe rent m ate rials w ith diffe rent propo rtions have been ra ised, and excursion occurred, and th is ex cursion is re lated to the doped e lem ents and the ir propor tions. Acco rd ing to the therm al spec trum corresponded to by the sam ple , d ifferen t ro les p layed by the elem ents a re ana lyzed from the m icro- structures of VO 2, Fe2O 3, P2O 5 in sam ple e lem ents. Components from sam ple analysis of the com ponen ts of the ro le o .f Design ra tio o f Three sam ples w ith d ifferent doped proportions are des igned and produced, and the ex cursions o f phase transition po in ts in the ir d iffe rent groups are compared. It follow s from this program that in the produc tion o f therm isto rCTR, each g roup has mutual in fluence on each other. The relative am ount o f VO 2 phase trans ition tem pera ture is d irec tly proportiona l to the re la tionsh ip; the re lative vo lum e o f P2O 5 has the im pact on VO 2 M icrocrysta lline stab ility, and also on the pr ice o f Fe2O 3 and e lectron ic conduction, thus affec ting the phase- change ofVO2; the volum e o f Fe2O 3 is directly propo rtional to conduc tiv ity of VO 2, .i e. , the large r the re la tive ly amount, the low er the phase transition tem pera ture.
