摘要:
A continuous process of forming a magnesium oxide-based product. The process includes preparing a feedstock, transferring the feedstock to a continuous curing process occurring at elevated temperatures and pressures, and drying the product of the continuous curing process. The process can further include lamination processes occurring after drying or in conjunction with curing. The continuous process reduces costs and times associated with traditional processes.

The present invention refers to nanocrystaline spherical ceramic oxides, to the process for the synthesis and use thereof. These oxides, obtained by detonation of a water-in-oil emulsion (W/O), besides having a spherical morphology and nanocrystallinity, show a set of complementary features, namely a particle dimension inferior to 40 μm, bimodal particle size distribution, high purity, deagglomeration and stable crystalline stages. This set of features makes these powders particularly suitable for several applications such as coating processes, near net shape processes and, when applied in ceramics industry, they provide dense and porous ceramic objects of exceptionally high mechanical resistance.
