Silicon nitride ceramic part and manufacturing method thereof
The invention relates to the field of ceramic materials, in particular to a silicon nitride ceramic part and a manufacturing method thereof. The silicon nitride ceramic part is prepared from the following raw materials in percentage by mass: 50-80% of silicon powder, 20-50% of alpha-Si3N4, a binder accounting for 5-30% of the total mass of the silicon powder and alpha-Si3N4, and a sintering aid accounting for 0.5-5% of the total mass of the silicon powder and alpha-Si3N4, the silicon powder is industrial silicon powder, the purity is 99.5% or above, and the particle size of the powder is 5-70 microns; and the median particle size of the alpha-Si3N4 is 10 +/-0.5 [mu] m. The silicon nitride ceramic part provided by the invention not only can maintain the performance advantages of high strength, high bending resistance and high hardness of silicon nitride ceramic, but also can reduce the production cost and achieve the purpose of market promotion. The invention also provides a preparation method of thesilicon nitride ceramic part.
本发明涉及陶瓷材料领域，具体涉及一种氮化硅陶瓷零件及其制造方法。本发明所述的氮化硅陶瓷零件，由以下质量百分比的原料制造而成：硅粉50～80％，α‑Si3N420～50％，粘结剂的质量占硅粉和α‑Si3N4总质量的5～30％，助烧剂的质量占硅粉和α‑Si3N4总质量的0.5～5％；硅粉为工业硅粉，纯度99.5％以上，粉末粒径为5～70μm；α‑Si3N4的中位粒径为10±0.5μm。本发明提供一种氮化硅陶瓷零件，既能保持氮化硅陶瓷的高强度、高抗弯性能、高硬度的性能优势，又能降低生产成本，达到市场推广的目的；本发明还提供其制备方法。
