Porous Glass Ceramic Bioimplants
Glass and Ceramics, 2000A technology for producing porous glass ceramic implants has been developed using foam polyurethane as the burning-out forming matrix. Porous glass ceramics with pore sizes of 300 – 500 and 600 – 700 μm were obtained. Sanitary-chemical, toxicological-hygienic, and medicobiological tests were carried out.

The possibility of producing strong porous ceramics based on aluminum oxide is shown. SiC with an activating additive and ammonium bicarbonate are used as a binder and a pore agent, respectively. The effect of the amount of the additives thus introduced and firing temperature on the porosity and strength of the material is studied.

Porous piezoelectric ceramic hydrophone
The Journal of the Acoustical Society of America, 1999The construction and evaluation of a hydrophone based on porous piezoelectric ceramics with high dhgh figure of merit (FOM) is described. It has been shown that, in order to improve the hydrophone signal-to-noise ratio, a piezoelectric material with a high FOM should be employed. A porous piezoelectric material has been prepared by mixing calcined lead

Porous Piezoelectric Ceramic Transducer
Japanese Journal of Applied Physics, 1991Porous piezoelectric ceramics of Pb(Zr, Ti)O3, (P-PZT), have been newly developed to apply to transducers in an echo sounder. The P-PZT was prepared from a mixture of PZT and poly-methyl-methacrylate (PMMA) powders. The piezoelectric characteristics of the P-PZT such as the dielectric constant (ε), voltage output constant (g constant), acoustic ...
