釉面硬度升级研究

Research of Improving Glaze Hardness

本文主要研究了Ca O-Mg O-Al_2O_3-Si O_2多元配方系统添加不同硬质晶体后的釉面硬度改善情况。引入的主要硬质晶体有堇青石、电气石、钙长石、立方氮化硼、α-Al_2O_3、超细石英以及利用海泡石结构自制的纳米氧化锆。根据研究数据发现,无论是在抛釉A-PS中添加单一硬质晶体还是添加多种硬质晶体都可以使釉面划痕硬度达到6甚至大于6,但是经过抛光之后,釉面硬度又会降低。而且得出了最佳配比为在A-PS添加5%的1μmα-Al2O3基础上再添加2000目超细石英粉,其抛光前硬度为6.5,抛光后硬度为5.5。

This paper mainly studied the Ca O-Mg O-Al_2 O_3-Si O_2 multivariate formula system after adding different hard crystal glaze hardness to improve the situation. To introduce the main hard crystals have cordierite, tourmaline, calcium feldspar, cubic boron nitride, alpha Al_2 O_3,ultrafine quartz and using sepiolite structure home-made nanometer zirconium oxide. According to the data found that both in the glazed ceramic A-PS adding a single rigid crystal or adding a variety of hard crystal glaze can make scratch hardness reach 6 or more than 6, but after polishing, glaze hardness will reduce. And obtained the optimal proportion is 5% in A-PS add 1 μm α-Al_2 O_3 add 2000 mesh based on superfine quartz powder, the polishing before 6.5 hardness, hardness of 5.5 after polishing.
