Eight novel silicate, phosphate and borate glass compositions (coded as NCLx, where x = 1 to 8), containing different oxides (i.e. MgO, MnO2, Al2O3, CaF2, Fe2O3, ZnO, CuO, Cr2O3) were designed and evaluated alongside apatite-wollastonite (used as comparison material), as potential biomaterials for bone tissue repair and regeneration. Glass frits of all the formulations were processed to have pa...

Ceramifiable styrene-butadiene (SBR)-based composites containing low-softening-point-temperature glassy frit promoting ceramification, precipitated silica, one of four thermally stable refractory fillers (halloysite, calcined kaolin, mica or wollastonite) and a sulfur-based curing system were prepared. Kinetics of vulcanization and basic mechanical properties were analyzed and added as Suppleme...

We prepared a prosthesis for the replacement of the lumbar vertebrae of sheep, using apatite- and wollastonite-containing glass-ceramic. The material is stronger than human cortical bone and has the special feature of chemical bonding to bone. Ten sheep underwent replacement of L3 and L4 vertebrae, without bone grafting. The animals were killed at intervals from three months to 27 months after ...

Green et al. (1) report 2 y of increased evapotranspiration (ET; calculated as the difference between total precipitation and total runoff) and decreased water yield following watershed-scale amendment of soil with wollastonite (CaSiO3) at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire. The watershed manipulation study was planned and executed within the context o...

Biocoatings were formed on the surface of Mg0.8Ca alloy by method micro-arc oxidation, in an electrolyte containing β-Ca3(PO4)2 (β-TCP) and CaSiO3, When process voltage was varied range 350–500 V, thickness, roughness, mass coatings increased to values 110 µm, 12 11 mg, respectively. The presence following crystalline phases determined coatings: α-TCP, wollastonite, forsterite magnesium oxide. ...

K-struvite, the main hydrate of magnesium potassium phosphate (MKP) cements, dehydrates at ~50 °C, thus elevated temperatures service conditions could affect cement properties and durability. In this study, hydration MKP without with wollastonite were investigated 20 50 °C. hydrated pure K-struvite decomposes progressively over time to MgKPO4·H2O which leads a strong reduction solid volume seve...
