[0070] Preparation Example 1: Capacitor
[0071] The preparation method of each embodiment of the present invention is the same as the preparation method, and the process description is as follows: using the mixed solution of ethanol and toluene as the solvent, add 100 moles of the main mixture powder into the solvent, and add a commercially available dispersant, and uniformly mix with a bead mill. , to obtain the main mixed slurry; add the auxiliary mixture powder to the same solvent, and uniformly mix with a bead mill to obtain the auxiliary mixed slurry; wherein, the mole percentages of the auxiliary mixture powder shown in Table 1 and Table 2 below, Based on 100 mole percent of the main mix powder. Mix the main mixed slurry and the auxiliary mixed slurry, add commercial organic binder PVB, and uniformly mix with a bead mill to obtain a ceramic slurry; the ceramic slurry is formed into a ceramic thin film with a thickness of 10 microns by a coating machine. Tape; on the surf...
Embodiment 1-1 to Embodiment 1-6
[0079] The preparation methods of Examples 1-1 to 1-6 are the same as those described in Preparation Example 1; the formulations of Examples 1-1 to 1-6 and the capacitance permittivity, dissipation factor (DF) and capacitance value change rate The detection results of (TCC) are shown in Table 1. When the multilayer ceramic capacitors prepared by the formulations of the above examples meet the EIA-X8R standard, it is represented by O in the table.
[0080] As can be seen from Table 1, based on the total weight of the main mixture, when the content of the first main component powder is 60 to 90 percent by weight, the content of the second main component powder is 10 to 40 percent by weight; and the main mixture 100 mole percent, rare earth oxides are 2 mole percent to 4 mole percent, silicon oxides are 0.2 mole percent to 1 mole percent, and alkaline earth metal oxides are 1 mole percent to 5 mole percent, the capacitors can meet EIA- X8R standard; in addition, the dielectric c...
Embodiment 1-1、 Embodiment 1-2、 Embodiment 2-1 to Embodiment 2-13
[0083] The preparation methods of Example 1-1, Example 1-2, Example 2-1 to Example 2-13 are the same as those described in Preparation Example 1; The detection results of the capacitance value change rate (TCC) are shown in Table 2. When the multilayer ceramic capacitors prepared by the formulations of the above examples meet the EIA-X8R standard, it is represented by O in the table.
[0084] From the comparison between Example 1-1 and Example 2-1 and the comparison between Example 1-2 and Example 2-8 in Table 2, it can be seen that when the third main component powder is further added to the ceramic composition, the loss of capacitance The factors are all halved, it can be seen that the addition of the third main component powder can help to improve the dissipation factor of the capacitor.
[0085] Second, from the comparison between Example 2-4 and Example 2-7, it can be seen that increasing the addition amount of rare earth oxide can improve the loss factor of the capacito...
