Magnesium oxide powder for calcining high-temperature oven as well as preparation method and application thereof
The invention provides magnesium oxide powder for a calcining high-temperature oven as well as a preparation method and application thereof. The magnesium oxide powder is prepared from the following components in parts by weight: 95 to 99 parts of MgO; 0.5 to 1.2 parts of CaO; 0.25 to 0.5 part of Fe2O3; 0.1 to 0.4 part of Al2O3; 1.0 to 2.0 parts of SiO2; and less than or equal to 0.2 part of water(LOI). The invention further discloses a preparation method of the magnesium oxide powder for the calcining high-temperature oven. The temperature resistance, the service lifetime, the insulation andthe breakdown resistance of the magnesium oxide powder for the calcining high-temperature oven are superior to those of magnesium oxide for the high-temperature oven. A heating tube prepared from themagnesium oxide powder meets the national requirements on the leakage current of an electric heating element.
本发明提供一种煅烧高温烤箱用氧化镁粉、其制备方法及用途。本发明煅烧高温烤箱用氧化镁粉包括重量配比如下的各组分：MgO 95‑99份；CaO 0.5‑1.2份；FeO0.25‑0.5份；AlO0.1‑0.4份；SiO1.0‑2.0份；水(LOI)≤0.2份。本发明还公开了煅烧高温烤箱用氧化镁粉的制备方法。本发明煅烧高温烤箱用氧化镁粉的耐温性，寿命，绝缘和抗击穿性能优于高温烤箱用氧化镁。采用该氧化镁粉制备的发热管符合国家对于电加热元件泄漏电流的要求。
