Abstract
The utility model provides a microwave medium resonance temperature keeper matched with a microwave pressure-resistant sintering furnace. The utility model is suitable for sintering massive ceramics. The utility model is characterized in that a material layer with high dielectric constants, low loss and high quality factor is smeared at the side outer wall of an original multi-mould medium temperature keeper, such as TiO2, MgTiO4, and BaTi 4 O9. The utility model can greatly improve the rate of finished products of the ceramic materials of the microwave pressure-resistant sintering furnace.
Description
The utility model relates to stupalith agglomerating plant field.Specifically just provided a kind of and the matching used microwave-medium resonance of the withstand voltage sintering oven of microwave warmer.
Chinese patent 90226959.3 provides a kind of microwave withstand voltage sintering oven, is made of external shielding layer, multilayered medium muff and convergence antenna, is applicable to sintered ceramic material, and sintering time is short, power consumption is low, can big goods of sintering.Though former multilayered medium muff has good adiabatic heat-proof quality, but can not very effectively microwave be constrained in the thermal insulator and to form multimode resonance form, to making field energy skewness in the thermal insulator, burn to such an extent that the yield rate of ceramic objects is lower.
The purpose of this utility model is to provide a kind of microwave-medium resonance warmer, can be used with the withstand voltage stove of microwave, improves the yield rate of sintered ceramic product.
The utility model provides a kind of microwave dielectric resonator that is used for the withstand voltage sintering oven of microwave, form by two jacket casing dresses that have capping, the bottom of tube has viewing window, the internal layer thermal insulator is made by the hollow ball aluminum oxide, skin is made by sapphire whisker, the outer side wall that it is characterized in that outer layer barrel scribbles one deck high-k, and the coating of low-loss, high quality factor is as TiO

The utility model is owing to be coated with one deck high dielectric constant materials at outer side wall, make by assembling microwave multiple reflection in warmer that antenna is assembled and dispersed, stack repeatedly, form dozens of even up to a hundred microwave resonance patterns, the micro-wave energy of high field intensity is constrained in the sintering zone equably like this, and outside the sintering zone, field intensity is reduced to zero rapidly, guaranteed the quality of ceramic post sintering spare, be described in detail the utility model in conjunction with the embodiments below by accompanying drawing.
Accompanying drawing 1 is a kind of cut-away view of microwave-medium resonance warmer.Warmer among the figure is formed by the cylinder set of two bands capping, and the bottom has viewing window 2, and inner core 1 is made by the hollow ball aluminum oxide, and urceolus 4 is made by sapphire whisker, and the outer side wall of urceolus has a coating 5, is TiO
2The microwave of being launched by convergence antenna 3 enters into thermal insulator, in the scope of external coating (EC) constraint, constantly reverberate, stack forms up to a hundred modes of resonance repeatedly, thereby the microwave field energy is evenly distributed, guaranteed the equal Hengsheng temperature of sintered ceramic spare, made the yield rate of sintered ceramic rise to more than 90% by 50%.
