These semi-empirical approaches allow to get quite good data on the speed of propagation, which depends on the volume of fuel and moisture content of forest combustible materials, wind speed and terrain.
This led to the heating of forest combustible materials, evaporation of moisture, the beginning of the pyrolysis process with the subsequent release of gaseous pyrolysis products and their ignition.
During the study of the impact of wildland fires on buildings it was taken into account the influence of different parameters: a) meteorology (temperature of air, the value and direction of wind velocity and etc.), b) properties and state of forest combustible materials (type of vegetation, bulk, moisture etc.).

They can be used in many fields, such as lightweight construction materials, heat preservation and heat insulation material, fireproofing materials, expanded vermiculite plank materials, adsorption and filtration materials, soil improved materials, etc.
Generally, the samples are also suitable for lightweight constructer materials, heat preservation and heat insulation materials, adsorption and filtration materials, but not so good.
Based on the property characteristics of chlorite-vermiculite interstratified minerals from Cheng Village Mine, it is more suitable for mineral fertilizer soil improvement, adsorption and filtration materials etc.

The feedstock material used for deposition was WC-Co 83-17 powder (Thermico GmbH Dortmund, Germany) with a granulometric fraction of -30 +5 µm.
Both materials were subsequently deposited on Almen strips.
These phases influence the ductility of the material which protects the coating from the appearance of microcracks.
