Compounds of the Structural Type of Calcium Titanate [PDF]

open access: bronzeNature, 1945
IN a previous communication1, it was recorded that precision X-ray powder methods with a large-diameter camera show that the structure of nickel oxide is not strictly cubic, but only pseudo-cubic. Splitting of some of the X-ray reflexions into more than one component is explained if a small distortion of the cubic lattice along an octahedral axis is ...

Calcium L-edge XANES study of some calcium compounds [PDF]

open access: bronzeJournal of Synchrotron Radiation, 2001
The Ca L3,2-edge XANES spectra of six calcium salts have been measured in both total electron and fluorescence yields using a high-resolution spherical grating monochromator. The compounds investigated were; CaF2, CaCO3, CaCl2 ˙2H2O, calcium phosphate, calcium glycerophosphate and calcium gluconate.

Strengthening of Calcium Phosphate Cement by Compounding Calcium Carbonate Whiskers

open access: bronzeDental Materials Journal, 2005
The purpose of this study was to investigate how aragonite (calcium carbonate) whiskers influenced the strengthening and carbonating of alpha-tricalcium phosphate (alpha-TCP) based calcium phosphate cement. Aragonite whiskers of 0.95 microm width with an aspect ratio of 6.6 were prepared.

Electron-Beam Radiation Effects in Multilayer Structures Grown with the Periodical Deposition of Si and CaF2 on Si(111)

open access: yesMaterials Proceedings, 2023
The formation of CaSi2 films on Si(111) with the molecular-beam epitaxy (MBE) of CaF2 under fast electron-beam irradiation was investigated. The method of a high-planarity CaSi2 film synthesis assisted by electron-beam irradiation was developed.
