Domestic ceramic blank material and preparation process thereof

ZHOU XINWEN

The invention provides a domestic ceramic blank material and a preparation process thereof and belongs to the technical field of ceramics. The domestic ceramic blank material comprises an anti-reflection agent, the anti-reflection agent is cordierite, the content of silicon in the cordierite is 49-51%, the content of aluminum in the cordierite is 34-36%, the content of magnesium in the cordieriteis 12-14%, and the cordierite fineness is 325-425 meshes. According to the invention, cordierite is used as an anti-reflection agent to be added into the domestic ceramic blank material, and the cordierite has high refractoriness reaching 1400 DEG C, so that the problem of insufficient refractoriness caused by a solvent can be solved, magnesium in cordierite can be used as a cosolvent, so that theblank is more transparent, the problem that the whiteness and transparency of high-grade domestic ceramic cannot be compatible can be solved, and the prepared ceramic is high in refractoriness and does not deform.

本发明提供一种日用陶瓷胚体材料及其制备工艺，属于陶瓷技术领域，所述日用陶瓷胚体材料的原料包括增透剂，所述增透剂为堇青石，所述堇青石中的硅含量为49‑51％、铝含量为34‑36％、镁含量为12‑14％，所述堇青石的细度为325‑425目。本发明以堇青石为增透剂加入到日用陶瓷胚体材料中，堇青石本身耐火度高，达到1400℃，可以解决溶剂导致的耐火度不足问题；堇青石中的镁，可以作为助溶剂，使坯体更透，可以解决高档日用陶瓷的白度与透明度无法兼容的问题，且制得的陶瓷耐火度高，不变形。
