Aluminum carbide produces methane, which burns mostly invisible blue and would be unsafe for illumination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q: What happens if I leave the jar open overnight?<\/strong><br>A: Humidity in the air will react with the powder, releasing methane gas. The gas, being lighter than air, accumulates near the ceiling. A spark from a light switch could ignite it. By morning, the jar will contain only white aluminum hydroxide sludge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q: Why does it look dirty or green?<\/strong><br>A: Synthesis requires extreme heat, so unreacted black graphite or gray aluminum impurities often remain, giving the yellow crystals a muddy appearance.<\/p><div class=\"pai-ad\" style=\"min-height:250px;visibility:hidden;\"><span style=\"display: block; text-align: center; font-size: 10px; margin: 0 0 10px 0; color: #999999;\">Ads<\/span>\r\n<!-- Display-300x250-1 -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:inline-block;width:300px;height:250px\"\r\n     data-ad-client=\"ca-pub-3838168351244230\"\r\n     data-ad-slot=\"9933646018\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">10. <strong>Summary Data Sheet<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-center\" data-align=\"center\"><strong>Chemical Name<\/strong><\/th><th class=\"has-text-align-center\" data-align=\"center\">Aluminum Carbide<\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Formula<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">Al\u2084C\u2083<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Appearance<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">Mustard\u2011yellow or brownish\u2011green powder\/crystals<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Density<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">2.36 g\/cm\u00b3<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Hazard Note<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">Generates explosive methane on contact with humidity<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Primary Utility<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">High\u2011temperature copper additive; specialized lab reagent<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Extinguishing<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">Dry sand or Class D powder only. <strong>No water.<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n<\/p><script>document.addEventListener(\"DOMContentLoaded\",function(){\n        if(window.innerWidth <= 768){\n            if (\"immediate\" === \"delay\") {\n                setTimeout(function(){document.querySelectorAll(\".pai-ad\").forEach(el=>el.style.visibility=\"visible\")},0);\n            } else if (\"immediate\" === \"scroll\") {\n                window.addEventListener(\"scroll\",function(){\n                    let s=window.scrollY\/(document.body.scrollHeight-window.innerHeight);\n                    if(s>0.1){\n                        document.querySelectorAll(\".pai-ad\").forEach(el=>el.style.visibility=\"visible\");\n                    }\n                });\n            } else {\n                document.querySelectorAll(\".pai-ad\").forEach(el=>el.style.visibility=\"visible\");\n            }\n        } else {\n            document.querySelectorAll(\".pai-ad\").forEach(el=>el.remove());\n        }\n    });<\/script>","protected":false},"excerpt":{"rendered":"<p>Aluminium carbide is a fascinating, highly reactive inorganic compound defined by its extreme sensitivity to moisture.
