XRD spectra of synthesized BaO-NPs is shown in Figure 2. Many well-defined peaks correspond to various planes of BaO as (200), (201), (211), (102), (310) and (212), so on were seen in the...

Figure (1) shows the XRD pattern of the powdered barium oxide nanoparticles. The tetragonal structure of raw BaO is reflected in all peaks in the diffraction pattern. ... View in full-text

2022年4月15日 · The synthesis of cubic structure BaO NPs was confirmed through X-ray diffraction (XRD). The crystallite sizes calculated from X-rays diffractometric (XRD) results for undoped BaO and Nd-doped BaO were 10.50 nm and 10.04 nm, respectively.

X-ray diffraction analysis (XRD) revealed the formation of hexagonal and cubic crystalline-structure phases for ZnO and BaO nanoneedles, with an average crystallite size ranging from 28–31 nm.

2024年10月1日 · X-ray diffraction (XRD) results revealed that Mo was successfully doped into tetragonal nanocrystalline BaO. The W-H plot showed that as Mo doping increases from 2 % to 6 %, the crystallite size grows while the lattice structure remains well …

ray powder diffraction (XRD), is an instrumental technique that is used to identify the minerals, as well as other crystalline materials. XRD provides the researcher a fast and reliable tool for routine mineral identification. XRD is particularly useful for identifying fine grained minerals and mixtures or intergrowths of minerals that

2018年5月1日 · Here we present a near-edge X-ray absorption (NEXAFS) and X-ray photoelectron spectroscopic (XPS) study of four barium compounds: BaO, Ba(OH) 2, BaCO 3, and Ba(NO 3) 2. Using an ambient-pressure XPS instrument we prepared thin film samples in situ, which provided a high degree of control over the …

2001年8月30日 · In this paper we have shown from complementary DTA–TG and high-temperature XRD that the decomposition of the barium peroxide either in argon or oxygen flows cannot be described by a simple reaction order model in all the compositional field BaO 2 –BaO.

2022年1月13日 · DSC demonstrated that BaO increased the crystallization temperature of indialite and inhibited the precipitation of indialite. XRD indicated that the addition of BaO promoted the formation of (MgAl2Si3O10)0.6 and even stabilized the existence of (MgAl2Si3O10)0.6 phase.

2013年12月6日 · 通过SEM，STEM，XRD和FT-IR对所制备的BaO 2纳米颗粒进行表征，以验证粒径（直径为40 nm）和相纯度（例如，不存在BaO，Ba（OH）2和BaCO）3）。 BaO 2纳米颗粒由于原位释放O 2而成为强氧化剂，如de- N所证明的那样-Ampliflu Red的乙酰化和试卤灵的强红色荧光。 此外，它们还可以用于代替H 2 O 2的Luminol驱动的Fe 2+ / Fe 3+（<0.05 mmol）的化学发光检测。 与常规的H 2 O 2水溶液相比，BaO 2纳米粒子显示出高的储存稳定性（无自催化分 …
