| dc.description.abstract | Research on the effect of sinterring temperature in magnet NdFeB on physical
properties, magnetic properties and crystalline structure has been done. The
sinterring of kind 400o
C, 700o
C, 900o
C and 1000o
C with detention for an hour.
Characterized includes physical properties (bulk density), magnetic (flux density
and VSM) and crystalline structure (XRD). The process of making magnet NdFeB
of flakes NdFeB on the effect of sinterring temperature, where the milling on 72
hours using toluene. The process of making it do in vacuum with the nitrogen gas
medium. Based on the analysis of the structure of XRD in the manufacture of
magneticNdFeB of the sinterring 400o
Cto 1000 o
Cchanged crystal structure.
Strong field and bulk density of the magnet NdFeB that obtained in the effect of
sinterring temperature has declined or small. Results of testing VSM on crystal
powder without sintering NdFeB found that remanence value of 37.34 emu / g,
coersivity 1.07 kOeand BHmax 0.76MGOe, the values are greater than the
sinterring temperature of 400 o
Cand 900 o
C and overall crystalline powder is
Semi-Hard Magnetic. | en_US |
