Abstract

The aim of the presented investigation is the elaboration of non-halogen, nontoxic, ecologically sound, high-efficient, universal, composite fire extinguishing powders on the basis of domestic mineral raw materials which satisfy the following requirements: - are characterized with high performance properties and fire extinguishing ability; - are used for extinguishing of all classes of fires; - are used for extinguishing of large-scale fires, forest fires and at the same time provide the enrichment of burnt out soils with different necessary salts; - are used in large temperature range, as well as at such low temperatures when CO2, water and foam cannot be used; - at extinguishing will make heterogenic as well as homogeneous inhibition of burning process. Keywords: non-halogen, non-toxic, ecologically sound, composite fire extinguishing powders, performance properties, fire extinguishing ability, thermogravimetric analysis. 1 Introduction Since those early days, millions of dollars have been spent on campaigns to prevent forest fires. But the result is not always sufficient. Forest fires are one of the most dangerous natural phenomena, leading to considerable economic losses and ecologic effects. They initiate long-lasting changes of all components of landscape and change microclimate conditions of atmosphere on the surface of the
