Abstract
Disclosed is a snow making method incorporating nucleation agent particles into water and in spraying the water containing the nucleation agent particles onto a surface or into an ambiance whose temperature is lower than 0° C., by way of a device for producing snow or ice. The nucleation agent particles consist in silicate particles whose unit equivalent spherical diameter is lower than 15 μm, and preferably lower than 5 μm. Also disclosed is the powdery product for implementing the method.
Claims19
A snow making method comprising:
- subjecting nucleation agent particles to at least one activation treatment, said nucleation agent particles consisting of silicate particles having a unit equivalent spherical diameter lower than 15 μm, said at least one activation treatment creating at least one micro-cavity on the surface of said nucleation agent particles;
- incorporating the nucleation agent particles into water after subjecting the nucleation agent particles to the at least one activation treatment;
- and
- spraying said water containing said nucleation agent particles onto a surface or into an ambiance having a temperature lower than 0° C., by a device configured to provide snow or ice.
