Two methods were employed for measuring fire retardancy of minerals hydromagnesite, huntite and natural hydromagnesite/huntite
mixtures, on forest species. The first was based on DTG under N2 atmosphere, to isolate pyrolysis of forest species and the second on LOI for combustion measurements. The selected forest
species: Pinus halepensis Mill. and Cistus incanus L., were collected from a WUI zone and were treated with 5, 10, 15 and 20 mass/mass% of minerals. Regarding DTG analysis,
the minerals decrease pyrolysis rate and increase mass residue of forest species. Regarding LOI tests, minerals increase pilot
ignitability of forest fuels. Hydromagnesite exhibits the best overall performance.

TG/DTG curves can be used to estimate alimentary fats quality by determining the kinetic parameters and induction period of oxidation. Also, since the thermal decomposition reactions imply oxidative exothermic and

The application of derivativ thermogravimetry (DTG) to investigate polymerisation mechanisms is illustrated using the radical
polymerisation of di-n-alkyl itaconates as well as the photoinitiated polymerisation of methyl methacrylate by colloidal CdS. The thermal properties
of the resulting polymers are described. The advantages and disadvantages of DTG are discussed.

The thermogravimetric analysis of BTU was carried out for sample mass of 15 mg between 50 and 800 °C at heating rate of 10 K/min in nitrogen atmosphere on a NETZCH STA 409C/CD thermal analyzer. The TG-DTG curves of BTU are shown

characterisation. Therefore, many authors have used these techniques for various materials characterisation [ 12 – 32 ]. The present article describes TG, DTG, XRD and FTIR spectral data of Co(II)-exchanged montmorillonite (Co(II)-MMT) with EDA, TrMeEDA and TeMeEDA
The computer kinetic analysis of simultaneously obtained TG and DTG curves of CaCO3 decomposition has been carried out. Ten different kinetic equations have been tested to decide the mechanism which drives the reaction. Either a two-thirds kinetic equation (phase boundary process) or a Jander equation (diffusion process) satisfactorily describe the kinetic data of both decomposition curves. From these results we conclude there is no chance of differentiating between these two mechanisms by only the kinetic analysis of TG and DTG curves separately.
