Preparation method of carbon-containing refractory material
The invention discloses a preparation method of a carbon-containing refractory material, which takes titanium powder, silicon powder and crystalline flake graphite as raw materials, and adopts a combustion synthesis method to prepare TiC-SiC coated crystalline flake graphite under the conditions of vacuumizing and inert gas injection. The raw materials comprise, by mass, 51.43%-59.02% of titaniumpowder, 10%-11.48% of silicon powder and 29.5%-38.57% of crystalline flake graphite, and the total content of the raw materials is 100%. According to the method, a large amount of heat released by thereaction of Ti powder and graphite is used for triggering the reaction of Si powder and graphite, so that a TiC-SiC composite coating is formed on the surface of crystalline flake graphite. The silicon powder can achieve the effects of preventing an oxidant and improving the integrity and uniformity of a TiC-SiC coating in a combustion synthesis reaction, so that the technical problem that crystalline flake graphite cannot be fully utilized in a refractory material in the prior art is solved.
本发明公开了一种含碳耐火材料的制备方法，该方法以钛粉、硅粉和鳞片石墨为原料，采用燃烧合成法在抽真空并注入惰性气体的条件下进行TiC‑SiC包覆鳞片石墨的制备。所述原料按质量百分比计，钛粉51.43％～59.02％，硅粉10％～11.48％，鳞片石墨29.5％～38.57％，总含量为100％。本发明方法利用Ti粉和石墨反应放出的大量热量引发Si粉和石墨发生反应，从而在鳞片石墨表面形成TiC‑SiC复合涂层。硅粉在燃烧合成反应中可以起到防氧化剂和提高TiC‑SiC涂层完整性和均匀性的作用，从而解决了现有技术中鳞片石墨无法在耐火材料中得到充分利用的技术问题。
