Magnesium aluminate spinel porous ceramic and preparation method thereof
The present invention relates to a porous ceramic, particularly to a magnesium aluminate spinel porous ceramic, which is prepared from the following raw materials by mass: 100 parts of a main materialcomprising active alumina powder and light magnesium carbonate powder with the mass ratio of the active alumina powder to the light magnesium carbonate powder being 40-60: 60-40, 0.1 to 0.6 part of adispersant, 0.5 to 2 parts of an adhesive, and 100-200 parts of water. The magnesium aluminate spinel porous ceramic provided by the invention has an open through structure and high porosity.
本发明涉及一种多孔陶瓷，尤其是镁铝尖晶石多孔陶瓷，由以下原料按照质量份数制成：主料100份，所述主料包括：活性氧化铝粉和轻质碳酸镁粉，其中按照质量比，活性氧化铝粉：轻质碳酸镁粉为40～60：60～40；分散剂0.1～0.6份；粘结剂0.5～2份；水100～200份。本发明提供的镁铝尖晶石多孔陶瓷具有开放的贯通结构、空隙率大。
