Abstract
The utility model relates to a ceramic capacitor dielectric sintering calcining-endure structure, which is characterized by comprising an alumina porcelain encloser and a corundum-mullite load-bearing base plate, wherein the corundum-mullite load-bearing base plate is provided with at least one layer of ceramic capacitor calcining-endure unit; and the ceramic capacitor calcining-endure unit comprises a high-purity zirconia plate, a high-purity alumina basal plate and a plurality of high-purity zirconia circular cones, wherein the high-purity zirconia circular cones are distributed on the high-purity zirconia plate and support the high-purity alumina basal plate; the alumina porcelain encloser is placed on the corundum-mullite load-bearing base plate; and the alumina porcelain encloser is sheathed outside the ceramic capacitor calcining-endure unit. Compared with the prior art, the utility model has the advantages that the structure can greatly increase the capacity of a tunneled sintering kiln; due to the fact that the structure adopts a dense stacking mode, the ceramic capacitor is evenly heated, and thereby being more beneficial to the product uniformity.
Description
Technical field
The utility model relates to a kind of manufacturing equipment of ceramic capacitor, holds the sintering structure more specifically to a kind of ceramic capacitor dielectric sintering.
Background technology
At present, the sintering processing that the ceramic capacitor industry adopts mainly is the stacked mode of multilayer aluminium oxide ceramics saggar, as shown in Figure 1, its structure comprises corundum-mullite weight tray 30, is placed on the alumina porcelain saggar 40,41,42,43,44 on the corundum-mullite weight tray 30, is placed with a high-purity zirconia plate 11 in each alumina porcelain saggar.Its shortcoming is that the continuous tunnel furnace furnace cavity that occupies of saggar is big, and the ceramic capacitor dielectric green compact amount of actual load is few, and saggar is 20: 1 with the volume ratio that is sintered product, and is bigger for the waste of the energy.Secondly, because traditional alumina porcelain saggar multilayer stacks the dispersiveness that causes, it is inhomogeneous to make sintering process be heated, and the dielectric constant K value dispersiveness of final ceramic capacitor is bigger.
Summary of the invention
The purpose of this utility model is that prior art is improved, provide a kind of ceramic capacitor dielectric sintering to hold the sintering structure, can be so that being heated of ceramic capacitor be more even, the space that effectively utilizes the ceramic capacitor dielectric sintering to hold the sintering structure, the technical scheme of employing is as follows:
Ceramic capacitor dielectric sintering of the present utility model holds the sintering structure, it is characterized in that: comprise the alumina porcelain outer cover, the corundum-mullite weight tray, the corundum-mullite weight tray is provided with at least, and one deck ceramic capacitor holds the burning unit, ceramic capacitor holds the burning unit and comprises the high-purity zirconia plate, high purity aluminium oxide substrate and a plurality of high-purity zirconia circular cone, each high-purity zirconia circular cone is distributed on the high-purity zirconia plate, and support the high purity aluminium oxide substrate, the alumina porcelain outer cover is placed on the corundum-mullite weight tray, and the alumina porcelain outer cover is enclosed within ceramic capacitor and holds and burn the outside, unit.
A kind of scheme preferably, described ceramic capacitor are held the number that burns the unit and are at least two, and each ceramic capacitor holds the burning unit and stacks gradually.
In order in sintering process, effectively to discharge the organic principle in the ceramic capacitor dielectric green compact, have a plurality of through holes on the sidewall of described alumina porcelain outer cover.
The utility model beneficial effect against existing technologies is, this structure can greatly improve the production capacity of tunnel sintering furnace, and production capacity can improve 140% than traditional dress saggar mode according to statistics, and energy efficient is 50%; Because this structure adopts the intensive mode that stacks, it is more even that the ceramic capacitor dielectric green compact are heated, more help consistency of product, it is more concentrated that mainly to be the dielectric constant (K value) that is embodied in ceramic capacitor stack sintering processing than traditional multilayer alumina porcelain saggar.
