The main role of the ZrO2–MgO–CaO and ZrO2–MgO–CaO–SiO2 systems in the field of refractories
The increasing severity of the working conditions of refractories together with the necessity of available and economically feasible raw materials have changed the design approaches towards materials experiencing “in situ” modifications during use.The ...

Densification of lightweight aluminum borate ceramics by direct sintering of milled powders
Dense aluminum borate (Al18B4O33) materials were processed by simple milling-sintering of aluminum borate powders obtained by reacting calcined alumina and fine boric acid at temperatures of around 600–800ºC.

Different low-cost materials to prevent the alteration induced by formic acid on unstable glasses
The most frequent cause of glass degradation is environmental moisture, which is adsorbed on its surface forming a hydration layer that induces the rupture of the glass network.

Development of a robust method for the determination of fluorine in liquid petroleum products
A robust method for the determination of total fluorine in liquid petroleum products is developed. The methodology is based on the oxidative pyrohydrolytic combustion of the sample, followed by the analysis of the evolved gases absorbed in an absorbing ...
