class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The crystal structure of graphite is composed of a layered structure of hexagonal units, and the <a href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/carbon-atom\" target=\"_blank\" rel=\"noopener\">Kohlenstoffatome<\/a> within each layer form covalent bonds through sp\u00b2 hybridization.\u00a0Its\u00a0bond lengths are\u00a00.142 nm and bond energies are\u00a0413 kJ\/mol, so it can form stable six-membered ring planes. The layers are connected by van der Waals forces, with a layer spacing of 0.335 nm. And\u00a0the force of action is relatively weak, approximately 20 kJ\/mol, which\u00a0endows graphite with unique physical and chemical properties. The high stability within the layers gives it extremely high heat resistance. The weak interlayer forces make it easily separable into thin sheets or powders.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_chemical_stability_of_graphite\"><\/span>The chemical stability\u00a0of graphite<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>From the perspective of chemical thermodynamics, the reaction between graphite and oxygen produces carbon dioxide. (The chemical equation for this reaction is C + O2= CO2.) This\u00a0has a Gibbs free energy change of -394.36 kJ\/mol under standard conditions, which indicates\u00a0thermodynamic spontaneity. However, the actual occurrence of this reaction requires overcoming the kinetic energy barrier. With the atomic ordered arrangement on the surface of graphite,\u00a0the effective collision probability with oxygen molecules is low. At room temperature, the annual oxidation rate &lt; 0.01%, so the oxidation rate can be negligible. So it has\u00a0kinetic inertness, which\u00a0is considered non-flammable in conventional environments.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Basic_conditions_of_combustion_reactions_and_the_influence_of_powder_characteristics\"><\/span>Basic conditions of combustion reactions and the influence of powder characteristics<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong><b>\u00a0<\/b><\/strong><strong><b>Basic conditions of combustion reactions <\/b><\/strong><\/p>\n<p>Combustion will occur only when three conditions are met simultaneously: combustible material, oxidant (usually oxygen), and a temperature reaching the ignition point.<\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>T<\/b><\/strong><strong><b>he influence of powder characteristics <\/b><\/strong><\/p>\n<p><strong><b>Specific surface area<\/b><\/strong><\/p>\n<p>The specific surface area of graphite powders of different particle sizes varies, which significantly increases as the particle size decreases. The specific surface area of 100\u03bcm graphite powder is approximately 0.5 m\u00b2\/g. The specific surface area of 1\u03bcm powder can reach 50 m\u00b2\/g, and that of <a href=\"https:\/\/jinsuncarbon.com\/de\/produkt\/graphit-nanopulver\/\">nanometer-sized powder<\/a> even exceeds 100 m\u00b2\/g. The large specific surface area increases the contact area with oxygen, reducing\u00a0the activation energy of the reaction. Thus\u00a0making the combustion easier to occur.<\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>Dispersion state<\/b><\/strong><\/p>\n<p>When the powder forms a suspension in the air, it can fully mix with oxygen. When the concentration of graphite powder is 15-45 g\/m\u00b3, it is within the &#8220;explosion limit&#8221; range. At this point, the heat generated by the local combustion will trigger a chain reaction through heat radiation, thereby causing an explosion.<\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>Ignition point<\/b><\/strong><\/p>\n<p>The ignition point of block graphite is approximately 800\u00b0C. But when in powder form, as the specific surface area increases, the ignition point of the material significantly decreases. It is \u00a0shown\u00a0that the ignition point of 50\u03bcm graphite powder is 750\u00b0C. While 20\u03bcm powder drops to 680\u00b0C, and 5\u03bcm powder can be as low as 600\u00b0C.<\/p>\n<p><strong><b>\u00a0<\/b><\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Analysis_of_Factors_Affecting_the_Combustion_of_Graphite_Powder\"><\/span>Analysis of Factors Affecting the Combustion of Graphite Powder<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"The_critical_role_of_particle_size\"><\/span>The critical role of particle size<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The particle size is the key factor determining the flammability of graphite powder, which it can be discussed in three levels:<\/p>\n<p><strong><b>Micron level (1 &#8211; 100\u03bcm)<\/b><\/strong><\/p>\n<p>This is the grade of conventional industrial <a href=\"https:\/\/jinsuncarbon.com\/de\/produkt\/kunstliches-graphitpulver\/\">Graphitpulver<\/a>.

For example, 0.5 \u03bcm graphite powder can sustain combustion at 700\u2103 in an oxygen-rich environment. Its combustion rate reach 0.8g\/(cm\u00b2\u00b7s) and it releases approximately 32MJ\/kg of heat.<\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>Nanometer level (&lt; 100 nm)<\/b><\/strong><\/p>\n<p>Nanometer graphite powder exhibits special combustion characteristics due to its extremely high surface energy. In dry air, the oxygen molecules adsorbed on the surface accumulate heat through slow oxidation. And when the temperature rises to 60\u2103, it can trigger self-ignition. Additionally, the explosion limit concentration of nanometer powder is lower, which is approximately 5 &#8211; 30g\/m\u00b3, increasing the safety risk.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Synergistic_effect_of_oxygen_concentration_and_environmental_temperature\"><\/span>Synergistic effect of oxygen concentration and environmental temperature<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong><b>The influence of oxygen concentration<\/b><\/strong><\/p>\n<p>In an air environment, which oxygen concentration is 21%, the combustion of graphite powder requires a higher temperature. But in an oxygen-rich environment, which oxygen concentration is greater than 30%, the activation energy of the reaction decreases. And the ignition point can drop by 100-200\u00b0C, thereby the combustion rate is three times higher than in the air environment.<\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>The influence of environmental temperature <\/b><\/strong><\/p>\n<p>If the environmental temperature increases, the oxidation process will accelerate. For example, when the environmental temperature rises from 25\u2103 to 300\u2103, the oxidation rate of graphite powder increases by 10 times.
