Ceramic material and application thereof in fuse
The invention discloses a ceramic material and application in a fuse, the ceramic material comprises the following raw materials by weight: 2-5 parts of a modified filler, 8-10 parts of an additive, 90-100 parts of alumina and 10-15 parts of zirconia, the additive forms a silicon carbide structure in a high calcination process, in the sintering process, radial tensile stress and tangential pressure stress can be generated in the green body, and under the action of external force, the stress and the external force act, so that material cracks deflect in the diffusion process, the cracks are bifurcated, a part of fracture energy is consumed, fracture diffusion is restrained, and the service life of the material is prolonged. The modified filler and the additive can generate a bridging effect in a green body, and when the ceramic material is subjected to external force, the modified filler and the additive can form a bridge between broken crack surfaces, so that crack closing force is generated, and the strength of the material is improved.
本发明公开了一种陶瓷材料及在熔断器中的应用，该陶瓷材料包括如下重量份原料：改性填料2‑5份、添加剂8‑10份、氧化铝90‑100份和氧化锆10‑15份，添加剂在高煅烧过程中形成碳化硅结构，在烧结过程中能够在坯体内部产生径向张应力和切向压应力，在受到外力作用时，应力和外力发生作用，使得材料裂纹在扩散过程中发生偏转，裂纹出现分叉现象，消耗一部分断裂能，进而抑制断裂的扩散，改性填料和添加剂能够在坯体中产生连桥效应，在陶瓷材料受到外力作用时，改性填料和添加剂能在断开的裂纹面之间架桥，进而产生裂纹闭合的力，进而提升材料的强度。
