Crystal phase structures of glaze samples containing boric acid and colemanite were analyzed by X-Ray Crystallography (XRD) method.

In the present work, nano-sized 10B-enriched boron carbide (B4C) powders were prepared by carbothermal process using 10B-enriched boric acid (H3BO3) and citric acid (C6H8O7·H2O) as raw materials...

Long afterglow material SrAl2O4: Eu²⁺, Dy³⁺ were synthesized by solution combustion method, and the effects of the concentration of H3BO3 on phases, micromorphology, photoluminescence properties,...

2020年2月5日 · 2.1.2 X-ray diffraction analysis (XRD) The sample material was identified by powder X-ray diffraction measurements. The measurements were carried out on a PANalytical X'Pert Pro diffractometer device in Bragg-Brentano geometry. It uses a mirror for separating the Cu Kα1,2 radiation and an X'Celerator linear detector.

2009年9月18日 · Results of XRD patterns indicated that a pure phase BaAl 12 O 19 could be achieved at the firing temperature above 1300 °C doping H 3 BO 3 of 7.0 wt% as flux. The additions of flux H 3 BO 3 promoted the solid reaction and reduced the temperature forming BaAl 12 O 19 :Mn 2+ phosphor.

2017年10月1日 · 使用场发射扫描电子显微镜 (FESEM)、能量色散光谱 (EDX) 和 X 射线衍射 (XRD) 分析合成的镍纳米线的物理性质。 通过考虑硼酸浓度对合成的镍纳米线的表面形貌、生长长度、元素组成和晶体取向晶体的影响，对所得镍纳米线的物理性质进行了阐述。 该发现表明硼酸浓度不会影响合成镍纳米线物理性质的所有方面。 硼酸浓度不影响表面纹理和晶体取向。 然而，随着硼酸浓度的增加，得到的 Ni 纳米线越短。 能量色散光谱 (EDX) 和 X 射线衍射 (XRD)。 通 …

2015年11月22日 · Zachariasen[1]也曾经对硼酸晶体进行XRD测试，确定硼酸晶体为分子晶体，其晶体由硼酸分子组成，并且硼酸分子之间靠氢键相连（ O－H…O）而形成具有六角对称性的层面结构如图2所示。

2017年1月9日 · In this paper, the effects of the concentration of H 3 BO 3 on phases, micromorphology and luminescence properties of SrAl 2 O 4: Eu 2+, Dy 3+ powders were studied systematically. All the samples show similar XRD patterns and photoluminescence properties, while the morphology and persistence properties are different.

对硼酸 (H3BO3/B (OH)3)粉末进行XRD测试,确定其空间结构和所属对称点群;对硼酸晶体进行晶格振动模式分析,确定其有18个拉曼活性模式4Ag+2E1g+5E2g;并对其进行50~3800cm-1波段的Raman散射测试,利用理论结果对谱图进行了讨论,确定了各振动峰的特性. 百度学术集成海量学术资源，融合人工智能、深度学习、大数据分析等技术，为科研工作者提供全面快捷的学术服务。 在这里我们保持学习的态度，不忘初心，砥砺前行。

In this process, sulfur dioxide was used instead of sulfuric acid to obtain H3BO3. The purpose of this research is to produce boric acid from a cheaper and more environmentally friendly process.
