The performance and the result of sample preparation are also determined by the choice of the grinding jar and its ball charge. The EasyFit range of jars has been specially designed for extreme working conditions such as long-term trials, even at maximum speed of 800 rpm, wet grinding, high mechanical loads and maximum speeds as well as for mechanical alloying.
Measurements of the birefringence of sapphire, magnesium fluoride, and synthetic quartz from 3000 Å to 1500 Å are reported and are followed by a discussion of the methods of achromatizing quarter-wave plates and of linearizing the path retardation of a multiwave plate against wavelength (equichromatic wave plates).

Magnesium aluminosilicate (MAS) glass-ceramics containing spinel and quartz solid solution, have good mechanical properties, high transparency and good chemical stability [4], [7], [8].However, due to the high concentrations of SiO 2 and Al 2 O 3, the MAS glasses present high melting temperatures and viscosities, which make them difficult to prepare.. Some fluxes, like …

It is feasible to prepare magnesium silicate hydrate with quartz instead of silica fume. Additionally, as the Mg/Si molar ratio increases, so does the intensity of the M-S-H peak. When quartz was utilized as the siliceous raw material, except for the amorphous M-S-H peak at 10–13° in XRD patterns, the diffraction peaks of M-S-H were ...

In this study, reaction mechanisms of MKP cements with a high magnesium-to-phosphate (Mg/PO 4) molar ratio of 8 were investigated at two different water-to-solid (w/s) ratios of 0.5 and 5. The experimental findings show that the use of this high Mg/PO 4 molar ratio suppresses the formation of potassium-free magnesium phosphate hydrates. K ...
