K2O与Na2O在陶瓷坯体中的作用 K2O与Na2O都是碱金属氧化物,是瓷坯中的主要熔剂,由长石引入。它们能熔解部分的SiO2和Al2O3生成玻璃,填充于胎体骨架的空隙中,使胎体烧结,并能促使莫来石的成长,故可提高制品机械强度和瓷胎的透明度。由于Na2O的熔融温度和高温粘度均比K2O低,而且高温粘度变化较快,其膨胀系数又比K2O...
K2O—B2O3—SiO3系统玻璃结构的光谱研究 本文应用红外光谱和嘈曼光谱分析技术,研究了K2O-B2O3-SiO2系统玻璃的结构.结果表明,在SiO2/B2O3〉2的情况下,无论K2O/B2O3〉1,≈1,还是〈1,玻璃结构中均存在「BO3」,Si... 张丽娟,陈一鹏 - 《哈尔滨建筑大学学报》 被引量: 24发表: 1996年 Na2O—B2O3—SiO2玻璃分...
Both 2- and 3-dimensional activity diagrams for the MgO-Na2O-K2O-SiO2-Al2O3-H2O-HCl system at temperatures of 298 to 623 K and 1 bar pressure are presented, showing the stability fields and volumes of phlogopite, Mg-chlorite, muscovite, paragonite, microcline, albite, kaolinite, and Mg-...
The morphology of mica crystals formed in extruded glass-ceramics of the system SiO2–Al2O3–MgO–K2O–Na2O–F2 was characterized using transmission electron microscopy. Detailed information on the crystal shape could be obtained since mica crystals in the extruded material exhibit an extraordinary deg...
Several previous studies have shown that sandstones from different tectonic settings possess characteristic chemistry, particularly SiO2 content and K2O/Na2O ratio. Systematic variation of these variables with change in grain size in New Zealand greywackes shows that such discrimination can be extended to...
