Abstract

Continuous nanocrystalline coatings of hexagonal boron nitride (h-BN) with a thickness of ~1000‒350 nm are prepared from highly concentrated aqueous solutions of lithium and sodium borates, which display good film-forming properties. The borate solutions were applied on silicon substrates by spin coating followed by drying in air and treatment in ammonia at a temperature of 1300°C. This method is deemed promising for creating protective coatings (e.g., for protecting carbon products from oxidation at elevated temperatures).

碱金属硼酸盐的浓溶液合成六方氮化硼涂层

摘要

六方氮化硼（h -BN）连续纳米晶涂层的厚度约为1000-350 nm，它是由高浓度的硼酸锂和硼酸钠水溶液制成的，具有良好的成膜性。通过旋涂将硼酸盐溶液施加到硅基底上，然后在空气中干燥并在1300℃的温度下在氨中处理。该方法被认为有望用于产生保护性涂层（例如，用于保护碳产品在高温下不被氧化）。
