PENGARUH PENAMBAHAN FRIT GELAS TERHADAP KARAKTERISTIK DIELEKTRIK KAPASITOR KERAMIK FILM TEBAL BATIO3
Abstract: Thick film
dielectric ceramic capacitors have been manufacture with an additive mixture
ofBaTiO3 95 % : 5 % , 92.5 % : 7.5 % and 90 % : 10 % regarding the frits glass
weight. Themixedsamples to the forms of pasta by adding 20%organic compounds
heaviness. Formedpasta from the three types of samples sintered at a
temperature of 700 C for 20 minutes.Then the
characteristics of the sample by using XRD, SEM and LCR metersis done.
XRDresults identified that all three types of samples formed BaTiO3 phase with
a tetragonalcrystal structure that the length of the crystal grid is a =
b ≠ c and angles α = β = γ . Theresults of SEM analysis showed BaTiO3 thick
film microstructure changes by indicated theincrease in grain. Dielectric
characteristics by measuring the capacitance of a capacitor attemperature of 30C - 100C. The results turned be a thick film capacitors with 5%
fritcomposition has a dielectric constant of 230.75, 7.5% frit composition has
a dielectricconstant of 39.58% and 10% frit composition has dielectric
constant of 293.87% attemperature of 100C. These
three dielectric constantvalues indicated 10% frit composition isthe highest
dielectric constant of the capacitor and is the best of the three types of
capacitor .
