Inorganic metal oxides

It is intended to use these properties for the assessment of alternative flame retardants (FRs) (including nanoparticles, phosphates, and inorganic metal oxides) in comparison with brominated fire retardants by quantitatively assessing ... 

In preparing fine particles of inorganic metal oxides, the hydrothermal method consists of three types of processes hydrothermal synthesis, hydrothermal oxidation, and hydrothermal crystallization. Hydrothermal synthesis is used to synthesize mixed oxides from their component oxides or hydroxides. The particles obtained are small, uniform crystallites of 0.3-200 jim in size and dispersed each other. Pressures, temperatures, and mineralizer concentrations control the size and morphology of the particles. In the hydrothermal oxidation method, fme oxide particles can be prepared from metals, alloys, and intermciallic compounds by oxidation with high temperature and pressure solvent, that is, the starting metals are changed into fine oxide powders directly. For example, the solvothermal oxidation of cerium metal in 2-mcthoxycthanol at 473-523 K yields ultrafine ceria particles (ca 2 nm).

The oxidative degradation capacity of tillers, inorganic (metal oxides, particularly free metal-containing) colorants, and other additives in WPC is greatly underestimated by many researchers and manufacturers of composites. Composite materials generally require much more antioxidants compared to neat plastics, particularly when an energy-intense compounding is employed.

Fly ash is usually collected in a bag filter. It contains various organic toxic compounds including dioxins, as well as inorganic metal oxides and heavy metals. The size of these particles is very small, typically about 40 pm. To avoid secondary pollution, it is imperative to treat the ash before re-use or before burying at land-fill site.
