- the flat panel display 100 described above can be manufactured by mounting and bonding.
- the face plate 101 having the black matrix structure 102 and the back plate 201 having the cathode structure 202 can be prepared by a known method.
- Al O powder (average particle diameter 0.5 zm, purity 99.9%), TiC powder (average particle diameter 0.5 ⁇ m)
- the mixture was ground and mixed with ethanol in a ball miner for 30 minutes, and spray-granulated at 150 ° C in nitrogen to obtain a granulated product.
- the Al O powder, TiC powder, Mg powder, and TiO powder are combined.
- each of these mixtures was primarily molded at about 0.5 MPa (50 kgf / cm 2 ), and was subjected to a hot press method in a vacuum atmosphere for 1 hour, a sintering temperature of 1600 ° C., and a press pressure of about 30 MPa (about 3 MPa).
- the resultant was fired at 00 kgf / cm 2 ) to obtain a plate for spacer for each Example 1.
- the content of powder should be 50.5% by weight and the content of MgO powder should be 40.0% by weight.
- Example 3 Twenty three A plate for a spacer of Example 3 was obtained in the same manner as in Example 1, except that the content was 45.5% by weight and the content of Mg powder was 45.0% by weight. 40.5 weight of Al O powder content
- Example 4 a plate for a spacer of Example 4 was obtained in the same manner as in Example 1 except that the content of Mg ⁇ powder was set to 50.0% by weight. The content of Al O powder was 35.5% by weight,
- a plate for a spacer of Example 5 was obtained in the same manner as in Example 1, except that the content of the powder was 55.0% by weight.
- the content of powder should be 60.5% by weight and the content of MgO powder should be 30.0% by weight.
- a plate for spacer of Comparative Example 2 was obtained in the same manner as in Example 1, except that the content of 23 was 30.5% by weight and the content of MgO powder was 60.0% by weight.
- Example 6 In the same manner as in Example 2, a plate for spacer of Example 6 was obtained. In addition, the inclusion of Al O powder
- Example 23 Same as Example 2 except that the content was 51.0% by weight and the content of powder 10 was 2.0% by weight.
- Example 8 was repeated in the same manner as in Example 2 except that the content of the TiO powder was 3.0% by weight.
- a plate for spacer was obtained.
- the content of Al O powder was 49.5% by weight
- a spacer plate for a spacer of Example 9 was obtained in the same manner as in Example 2, except that the content of the powder was changed to 3.5% by weight.
- Example 10 In the same manner as in Example 2, a plate for spacer of Example 10 was obtained. In addition, Al O powder
- a plate for a spacer of Example 11 was obtained in the same manner as in Example 2, except that the content of 23 was 49.5% by weight and the content of the TiC powder was 8.0% by weight. In addition, the content of Al O powder was set to 48.
- a plate for a spacer of Example 12 was obtained in the same manner as in Example 2 except that the content of TiC powder was 5% by weight and the content of TiC powder was 9.0% by weight.
- Figure 16 shows the relationship with degrees.
- the specific resistance was measured by using a digital multimeter manufactured by Advantest and applying an electric field of lOOOV / mm to the spacer plate.
- the three-point bending strength was measured with an autograph material tester manufactured by Shimadzu Corporation at a span distance of 30 mm and a crosshead speed of 0.1 mm / min.
- Figure 15 As is apparent, when the content of MgO as in Example 1 one 12 is a 35- 55 wt%, the thermal expansion coefficient of 8. 0- 9. 3 X 10- 6 / ° It is about C. Further, as is clear from FIG. 15, the content of Ti ⁇ is 2.0-3.0% by weight as in Examples 1, 5, 7, 8, and 10-12.
- the specific resistance is about 1.0 ⁇ 10 6 -1 ⁇ OX 10 " ⁇ ⁇ cm.
- a spacer having a strength of 400 MPa or more, which is generally preferred, is used.
- the content of Ti C is 7 to 8% . If the concentration of TiC is too high, it is considered that the sinterability is lowered and the strength is lowered.
