Zirconium is considered to be non-toxic. Characteristics: Zirconium is a strong, malleable, ductile, lustrous, grayish-white metal. It is generally exceptionally resistant to corrosion. It is however rapidly attacked by hydrofluoric acid, even at low concentrations. Powdered zirconium can spontaneously ignite in air.

When a mixture of alkali hydroxides and zirconium is heated, the liberated oxygen reacts explosively with zirconium [Mellor 7:116 1946-47]. Chromates, dichromates, sulfates, molybdates, and tungstates of lithium, sodium, potassium, rubdium, and cesium will react violently, even explosively, with an excess of zirconium powder [Ellern 1968. p ...

The information presented in Table 1 shows that Zr 1 zirconium powder contains less hydrogen and the hydrides are not registered by X-ray diffraction. Hydrogen in the atomic form has very limited solubility in the zirconium and zirconium alloys: less than 1 ppm at room temperature, about 80 ppm at 573 K and near 200 ppm at 673 K [21,22]. …

Zirconium is highly transparent to neutrons. It is therefore useful in nuclear energy applications such as in the cladding (outer layer) of fuel rods through which it is important that neutrons can travel easily. When it is finely divided into a powder, zirconium can spontaneously ignite in air, especially at high temperatures.

This study focused on the preparation of metallic uranium and uranium-zirconium alloys to measure the effect significant porosity had on thermal diffusivity from 20 ∘ C to 300 ∘ C. Precursor uranium powders were prepared through a hydride de-hydride process to obtain a < 70 mesh powder. The sample compositions were uranium, …
