Soluble ceramic fiber and preparation method thereof
The invention provides a soluble ceramic fiber. The soluble ceramic fiber comprises the following components in percentage by mass: 62-68wt% of SiO2; al2O3: less than 3wt%; caO: 25 to 32 wt%; mgO: 4 to 7 wt%; less than 0.3 wt% of K2O + Na2O; the content of P2O5 is 0.01 to 0.1 percent by weight; sO3: 0.005 to 0.1 wt%; wherein the total mass fraction of the P2O5 and the SO3 is 0.01 to 0.2 weight percent; 33wt% < CaO + MgO + 10SO3 < 38wt%. P2O5 and SO3 are introduced through pulverized coal, SO3 and P2O5 are matched, and the content is controlled within a certain range, so that the temperature range of melt fiber forming can be increased, the fiber content is further increased, and the content of non-fiber substances in the fiber is reduced. The invention also provides a preparation method of the soluble ceramic fiber.
本发明提供一种可溶陶瓷纤维，包括以下质量分数的成分：SiO2：62～68wt％；Al2O3：＜3wt％；CaO：25～32wt％；MgO：4～7wt％；K2O+Na2O：＜0.3wt％；P2O5：0.01～0.1wt％；SO3：0.005～0.1wt％；其中，P2O5与SO3的总质量分数为0.01～0.2wt％；33wt％＜CaO+MgO+10SO3＜38wt％。本发明通过煤粉引入P2O5与SO3，SO3与P2O5配合并将含量控制在一定范围内后，会增加熔体成纤的温度范围，进而提高纤维含量，降低纤维中非纤维物质的含量。本发明还提供了一种可溶性陶瓷纤维的制备方法。
