Kinetics of acquisition and loss of calcium fluoride
Heavy-duty anti-seize materials containing graphite and calcium fluoride
can lubricate extruding and forming dies, shear blades, metal-bending equipment, cold- and warm-forging dies and other process equipment.
In this respect, the absence of the secondary calcium fluoride
minerals gearksutite and creedite in the vugs with the new lead fluorides, and the presence of essential calcium in only one of the new lead fluorides, calcioaravaipaite, is notable.
Topical fluorides are believed to form a barrier by precipitating calcium fluoride
on the exposed dentin surface and reduce dentin permeability.
The bioavailable fluoride (F) deposits in the oral environment are primarily in the form of calcium fluoride
At 157 nm, the optics are made from calcium fluoride
When the two are combined just before or after entering the mouth, a calcium fluoride
precipitate forms only after the calcium and floride ions have a chance to infiltrate the tooth lesions and diffuse into plaque.
Tenders are invited for Supply of calcium fluoride
13,14) Fluoride-containing bleaching agents may generate fluoridated hydroxyapatite and calcium fluoride
crystals on the enamel, which may accelerate the remineralization of the bleached enamel.
However, based on the concept that the formation of calcium fluoride
Melting point of titanium is 1660 [degrees]C, and of calcium fluoride
(the most refractory component of the flux)--1410 [degrees]C, whereby melting point of multicomponent salt systems is, as a rule, lower .
The refractive index, dispersion, and thermo-optic coefficient of the lens materials, commonly fused silica for the 193 nm stepper and calcium fluoride
for the 157 nm stepper, have to be accurately determined to allow optical engineers to model the diffraction-limited exposure patterns.
