Preparation method of reactive sintering silicon carbide
The invention discloses a preparation method of reactive sintering silicon carbide, and relates to the technical field of inorganic non-metallic materials, which comprises the following steps in sequence: step 1, preparing main materials: carbonized powder, high carbon yield resin, a pore forming agent, a solvent and a surfactant; wherein the carbonized powder is prepared from silicon carbide micro powder and activated carbon powder or carbon black in a ratio of 7: 3; the silicon carbide micro powder is green silicon carbide micro powder with the particle size of 6-10 microns, the particle size of the activated carbon powder or carbon black is 40-100 nm, the adopted carbonized powder is divided into the silicon carbide micro powder, the activated carbon powder or the carbon black, the components of the carbonized powder are environment-friendly and non-toxic, smoke generated during firing does not generate toxic gas, pollution to the environment is reduced, the process is simple, the cost is low, and the method is suitable for industrial production. The problem that a large amount of silicon carbide fertilizer is wasted can be solved, the cost of reactive sintering carbon is reduced, the situation that a blank needs to be screened into particles in the material preparation process is avoided, and the cost generated during sintering is reduced.
本发明公开了一种反应烧结碳化硅的制备方法，涉及无机非金属材料技术领域，依次进行以下步骤：步骤一、配置主料：炭化粉体、高残炭率树脂、造孔剂、溶剂、表明活性剂；其中，炭化粉体分为：碳化硅微粉、活性炭粉或炭黑其比例为7:3；碳化硅微粉为粒径在6～10μm的绿碳化硅微粉，活性炭粉或炭黑的颗粒粒径均为40～100nm，通过采用的炭化粉体分为：碳化硅微粉、活性炭粉或炭黑其成分环保无毒，使在烧制使产生的烟也不会产生毒气，减少对环境的污染，本发明流程较为简单，能够解决大量的碳化硅肥浪费的问题，降低反应烧结碳的成本，且备料过程中需要将，没有将毛坯筛分成粒状的情况，降低了用烧结时产生的成本。
