Silicon carbide honeycomb ceramic material and preparation method
The invention provides a silicon carbide honeycomb ceramic material. The silicon carbide honeycomb ceramic material comprises the following raw materials in parts by weight: 40-48 parts of activated silicon carbide powder, 5-15 parts of modified wollastonite powder, 2-10 parts of a sintering aid, 5-10 parts of a methyl cellulose adhesive and 12-18 parts of deionized water. The modified wollastonite powder is ground, ferric chloride is added in the grinding process for further grinding, the needle-shaped structure of the modified wollastonite powder is better moistened, accordingly, the needle-shaped structure of the modified wollastonite powder can be filled with silicon carbide powder more easily, the product compactness is higher in the calcining process, and the prepared ceramic material is better in compressive strength.
本发明提供了一种碳化硅蜂窝陶瓷材料，包括以下重量份的原料：活化碳化硅粉40‑48份、改性硅灰石粉5‑15份、烧结助剂2‑10份、甲基纤维素粘接剂5‑10份、去离子水12‑18份。本发明改性硅灰石粉通过对其研磨，研磨中加入氯化铁进一步的研磨，目的更好的对其针状结构进行润透，从而使其针状结构更易填充碳化硅粉，在煅烧中使产品密实性更强，制备的陶瓷材料抗压强度更好。
