“…This was rationalized by a lesser degree of dehydration at the lower synthesis temperature (and therefore higher TGA weight loss in the range 473–673 K). Subsequently, Kim et al (from South Korea) conducted similar experiments to make barium hexaferrite and obtained comparable results. , More recently, Adschiri et al reported the synthesis of surface-functionalized barium hexaferrite directly in a flow process …”

Nanomaterials are at the leading edge of the emerging field of nanotechnology. Their unique and tunable size-dependent properties (in the range 1-100 nm) make these materials indispensable in many modern technological applications. In this Review, we summarize the state-of-art in the manufacture and applications of inorganic nanoparticles made using continuous hydrothermal flow synthesis (CHFS) processes. First, we introduce ideal requirements of any flow process for nanoceramics production, outline different approaches to CHFS, and introduce the pertinent properties of supercritical water and issues around mixing in flow, to generate nanoparticles. This Review then gives comprehensive coverage of the current application space for CHFS-made nanomaterials including optical, healthcare, electronics (including sensors, information, and communication technologies), catalysis, devices (including energy harvesting/conversion/fuels), and energy storage applications. Thereafter, topics of precursor chemistry and products, as well as materials or structures, are discussed (surface-functionalized hybrids, nanocomposites, nanograined coatings and monoliths, and metal-organic frameworks). Later, this Review focuses on some of the key apparatus innovations in the field, such as in situ flow/rapid heating systems (to investigate kinetics and mechanisms), approaches to high throughput flow syntheses (for nanomaterials discovery), as well as recent developments in scale-up of hydrothermal flow processes. Finally, this Review covers environmental considerations, future directions and capabilities, along with the conclusions and outlook.

“…Of these methods, the hydrothermal method is very attractive due to its simplicity and because the resulting Ba‐hexaferrite is crystalline and monodispersed. Considerable work has been carried out on the hydrothermal synthesis of Ba‐hexaferrite 9–18 …”

“…Considerable work has been carried out on the hydrothermal synthesis of Ba-hexaferrite. [9][10][11][12][13][14][15][16][17][18] In the past, efforts have concentrated on searching for the appropriate conditions to obtain a high-quality Ba-hexaferrite product 19,20 and to understand the reaction mechanisms and the kinetics involved during the hydrothermal processing of Ba-hexaferrite. [21][22][23][24][25] In the present study, an attempt was made to apply a controlled hydrothermal synthesis involving the LaMer-Dinger principle 26 to synthesize monodispersed nanoparticles of Ba-hexaferrite.…”

Barium hexaferrite BaFe12O19 nanoparticles with a single‐domain size were synthesized using a controlled hydrothermal process involving the LaMer–Dinger principle and the Ostwald ripening mechanism. Nanocrystalline particles of BaFe12O19 were obtained when the molar ratio of the precursor composition Ba(OH)2·8H2O/γ‐Fe2O3 was 0.3 and the concentration of the suspension was about 1 wt%. The as‐synthesized crystalline BaFe12O19 platelets approximately 50 nm in length and 5 nm in thickness exhibited a saturation magnetization of 40 Am2/kg.
