Spray drying is a widely used method of converting liquid material (aqueous or organic
solutions, emulsions and suspensions) into a dry powder. Good flowability, narrow size …

The material extrusion technique of direct ink writing (DIW) has garnered recent interest for
the ability to create near-net shapes using polymer and/or ceramic based inks using low …

The fabrication of complex shaped Si 3 N 4 parts by conventional methods is challenging
due to its high hardness and mechanical strength. Additive manufacturing (AM) appeared as …

Many energy systems demand heat transfer at high temperatures to keep up with high
demand for power, so high‐temperature material that can perform and last under these …

Abstract Silicon nitride (Si 3 N 4) is of interest because of its high inherent fracture toughness
due to interlocking and elongated β-Si 3 N 4 grains, but it is difficult to economically produce …

Ceramic suspension is a basic ingredient for various ceramic processing, and designing a
ceramic suspension system is important to secure material processability in various …

Polycarboxylate superplasticizers based on acrylic acid (AA) and maleic anhydride (MAn)
were synthesized via free‐radical copolymerization with an ethylene glycol monomer and …

Calcination was used for surface modification of ultrafine silicon nitride powders, which
improved the flowability and dispersion stability of their slurries. Surface characteristics of …

In spite of their high surface charge (zeta potential ζ=+ 34 mV), aqueous suspensions of
portlandite (calcium hydroxide: Ca (OH) 2) exhibit a strong tendency to aggregate, and …

Hypothesis Flow curve measurement is commonly used to characterize the flow behavior of
concentrated suspensions. However, dynamic changes in the suspension inner …
