Curing of Highly Loaded Ceramic Suspensions in Acrylates
نویسندگان
چکیده
The objective of this study is to use differential scanning calorimetry (DSC) to characterize the curing kinetics of Al2O3 and hydroxyapatite suspensions in acrylates. The heat evolution of the acrylate premix and ceramic suspensions in dynamic and isothermal curing was measured. The calculated activation energies for the acrylate premix and the two ceramic suspensions were 133, 74, and 78 kJ/mol, indicating a catalytic effect of the ceramic fillers. The curing behavior of the two ceramic suspensions modeled with the autocatalytic polymerization model with satisfactory results.

Bioactive Glass-Ceramic Foam Scaffolds from ‘Inorganic Gel Casting’ and Sinter-Crystallization
Highly porous bioactive glass-ceramic scaffolds were effectively fabricated by an inorganic gel casting technique, based on alkali activation and gelification, followed by viscous flow sintering. Glass powders, already known to yield a bioactive sintered glass-ceramic (CEL2) were dispersed in an alkaline solution, with partial dissolution of glass powders. The obtained glass suspensions underwe...
متن کاملSeveral cases of undesirable effects caused by methacrylate ultraviolet-curing nail polish for non-professional use.
BACKGROUND Ultraviolet (UV)-curing nail polishes based on acrylates or methacrylates are currently also available for non-professional use. The Swedish Medical Products Agency recently prohibited one brand of UV-curing polish, because several consumers reported undesirable effects after using it. OBJECTIVES To investigate whether consumers with undesirable effects after using the UV-curing na...

In the present research, the aqueous suspensions of nano-sized YSZ particles were prepared using a common and available dispersant (Dolapix CE64) at different pH values and their stability were evaluated through the sedimentation height, viscosity measurement, and microstructural observation. Different amounts of dispersant were tested and the optimum percentage was examined by measuring the vi...
متن کاملDifferential photo-calorimetry of photopolymerizable ceramic suspensions
Suspensions of alumina powders in low-viscosity acrylate monomers were produced and their curing behaviour characterized. Although these suspensions contain 50 vol % Al2O3 particles, the viscosity is between 200 and 300 mPas. These suspensions were rendered ultraviolet-curable by the addition of photoinitiators sensitive to ultraviolet radiation. Photopolymerization kinetics were characterized ...
