Bismuth borate composite microwave ceramics synthesised by different ratios of H3BO3 for ULTCC technology

Enhanced flexural strength and microwave dielectric properties of Li2MgTi3O8-based low temperature co-fired ceramics

“…The TE 01δ shielded cavity method 20 was used to measure the microwave dielectric properties using a network analyzer (Model E5071C, Agilent Co., CA, USA). The τ f value could be calculated using the following formula: 21 where f T and f T0 denote the resonant frequencies at T (85 °C) and T 0 (25 °C).…”

Processing strategy and composite regulation on dielectric performance in Li2O–Al2O3–B2O3 dielectric systems using SrTiO3

“…This composition is expected to have low relative permittivity due to the low ion polarization of the components, and low sintering temperature based on the extremely low melting point of boron oxides (450 • C). 28,29 However, synthesis of this composition is challenging due to boric acid or boron oxide (boron source), being volatile and hydrophilic, risking stoichiometric deviations. Such an issue would induce lattice defects, thereby degenerating the microwave dielectric properties of ceramics.…”

“…In this paper, Li 2 BAlO 4 , a ternary system of Li 2 O–Al 2 O 3 –B 2 O 3 was proposed and explored for microwave dielectric applications for the first time. This composition is expected to have low relative permittivity due to the low ion polarization of the components, and low sintering temperature based on the extremely low melting point of boron oxides (450°C) 28,29 . However, synthesis of this composition is challenging due to boric acid or boron oxide (boron source), being volatile and hydrophilic, risking stoichiometric deviations.…”

Efficient detection of Al3+ and B4O72− over trigonal prism In(iii) complex

“…8 Notably, aluminum, which enters the human body through the ecosystem, is linked to increased morbidity and can cause neurotoxicity, resulting in diseases, such as Alzheimer's and Parkinson's diseases 9 and breast cancer. 10 Similarly, as an important chemical raw material, borax (Na 2 B 4 O 7 ·10H 2 O) is widely used in industrial 11,12 and consumer products, such as household cleaners, 12 moisturizers, 13 buffers, 14 and food preservatives. 15 Besides, boron is an essential element in the human body and is indispensable in many parts of the body, especially bones.…”
