Silicon-silicon carbide ceramic material with high elastic modulus
The invention relates to the technical field of silicon carbide ceramics, in particular to a silicon-silicon carbide ceramic material with high elastic modulus. The silicon-silicon carbide ceramic with the high elastic modulus is prepared from the following raw materials in percentage by weight: 80-92% of grain size distribution silicon carbide micro powder, 3-14% of a silicon source and 3-6% of a carbon source, the carbon source is divided into two parts, one part is selected from one or more of graphite, anthracite, petroleum coke and carbon black, and the addition amount of the part is 1-3%; the other part comes from an organic binding agent, and the addition amount is 2-5%; the organic binding agent is one or more of anthracene oil, asphalt and resin. According to the invention, the uniformity of each component of the raw material, especially the uniformity of free silicon after sintering, is effectively ensured, the elasticity modulus of the material is effectively improved, the metal impurity content of the silicon carbide raw material is greatly reduced, and compared with the traditional hydrogen chloride and hydrogen fluoride, the safety is greatly improved, and the metal impurity content after sintering is greatly reduced.
本发明涉及碳化硅陶瓷技术领域，具体涉及一种高弹性模量的硅‑碳化硅陶瓷材料。高弹性模量的硅‑碳化硅陶瓷的原料由以下重量含量的各物质制成：粒度级配碳化硅微粉80‑92％、硅源3‑14％，碳源3‑6％，碳源分两部分，一部分来自石墨、无烟煤、石油焦、炭黑中的一种或一种以上，该部分加入量为1%～3%；另一部分来自有机结合剂，加入量为2%～5%；有机结合剂为蒽油、沥青、树脂中的一种或一种以上。本发明有效的保证了原料各成分的均匀性，特别是烧结后游离硅的均匀性，有效提高了材料弹性模量，碳化硅原材料的金属杂质含量大幅降低，相比传统的氯化氢和氟化氢，安全性大幅提高，并且烧结后的金属杂质含量大幅降低。
