High-strength electric porcelain formula
The invention discloses a high-strength electric porcelain formula. The formula comprises the following raw materials in parts by weight, 15 to 25 parts of feldspar, 25 to 35 parts of bauxite, 35 to 45 parts of clay, 10 to 20 parts of alumina micro powder, 40 to 45 parts of silicon dioxide, 45 to 55 parts of aluminum oxide, 1 to 1.5 parts of ferric oxide, 1.0 to 1.8 parts of titanium dioxide, and3.0 to 4.5 parts of a mixture of potassium oxide and sodium oxide. According to the present invention, the strength of the formula is significantly improved, the strength of the porcelain is stabilized at 170 MPa or more, the breakdown rate of the product is 1.0% or less, and the steep wave passing rate is 100% or more, so that the strength of the porcelain is substantially improved compared to the strength of the existing formula; moreover, the formula has the characteristics of low cost and excellent performance, compared with bauxite in the prior art, the alumina micro powder has the advantages that the impurity content is very low, the mechanical property and the electrical property of a high-strength porcelain product are obviously improved, the formula provided by the invention is excellent in process performance, and firing can be carried out under the condition that an existing firing system is not changed.
本发明公开了一种高强度电瓷配方，包括以下重量份的原料：长石15‑25份，铝矾土25‑35份，粘土35‑45份，氧化铝微粉10‑20份，二氧化硅40‑45份，三氧化二铝45‑55份，三氧化二铁1‑1.5份，二氧化钛1.0‑1.8份，氧化钾和氧化钠混合物总量3.0‑4.5份。本发明配方的强度有了明显的提高，瓷强度稳定在170MPa以上，产品击穿率1.0％以下，陡波通过率100％以上，和现用配方相比，有了大幅度提升；而且具有较好的经济效果，本发明配方具有成本低，性能优的特点；本发明中氧化铝微粉与现有技术中铝矾土相比，杂质含量很低，对高强度瓷产品的机械性能和电气有了明显提高；本发明配方的工艺性能优良，能够在现有烧成制度不变的情况下进行烧制。
