Al2O3-Strengthened Feldspathic Porcelain Bodies: Effects of the Amount and Particle Size of Alumina

Mechanical behaviour of a low-clay translucent whiteware

“…14 Therefore, an increase in crystal size and second phase formation are desirable. It was reported by several authors that alumina, 15 cristobalite, 16 silica fume, 17 rice husk ash 18,19 and mullite 7 in whitewares each strengthen the fired body.…”

Quartz particle size and cooling rate effects on microstructural defects and mechanical properties of feldspar-based ceramic materials

“…Ceramic materials are often manufactured using raw materials that contain dispersed in its matrix crystalline particles of quartz, alumina and zircon [3]. These crystalline particles have physical and chemical properties that are distinct from the glassy phase, strongly influencing the mechanical behavior of ceramic materials, such as flexural strength [4][5][6],…”

Effects of Extrusion Processing Factors on Reliability of Ceramic Packed Bed Applied for Chemical Contactors

“…The nonplastic materials have a significantly large particle size than the clays and provide the network support for body. The porcelain strength linearly increases with the amount of alumina, and the maximum strength is achieved in the presence of fine particles, 1–2 μm …”
