Fabrication of in-situ self-reinforced Si3N4 ceramic foams for high-temperature thermal insulation by protein foaming method

the Properties and Fabrication of Al 2 O 3 Porous Ceramics by Protein Foaming Method

“…Liuyan Yin et al [9] also studied the effect of rotational speed on pore size distribution and performance of silicon nitride foam material prepared by protein foaming method.The result indicated that the pore size data of the asprepared Si 3 N 4 foams abided by the logarithmic normal distribution and with the increase of rotating speed, the pore structure of Si 3 N 4 foam became more uniform. The research [10] prepare a stoichiometric hydroxyapatite material using calcined HAP powder and egg white as a bio and non-toxic pore promoter.The research Stoichiometric hydroxyapatite (Ca 10 (PO) 6 (OH) 2 , HAP) foams have been produced.The use of the egg white protein as pore former provides a total porosity of 86 vol% and a foam-structure that allows to a microporous wall.The research [11] fabricate lightweight and high-strength ceramic foams, in-situ self-reinforced Si 3 N 4 ceramic foams, with compressive strength of 13.2-45.9MPa, by protein foaming method combined with sintered reaction-bonded method. Vladimir Rybakov1 et al [12] study the combustibility of monolithic foam concrete based on a protein foaming agent with a density of 200kg/m 3 used for enclosure structures in the form of lightweight steel concrete structures.…”
