Il est presque insoluble dans l&#039;eau et l&#039;alcool, mais r\u00e9agit avec l&#039;acide ac\u00e9tique, l&#039;acide chlorhydrique et l&#039;acide nitrique dilu\u00e9s. Il p\u00e9tille et se dissout au contact de ces acides. Chauff\u00e9 \u00e0 898 \u00b0C, il se d\u00e9compose en oxyde de calcium et en dioxyde de carbone. Utilisations\u00a0: <a href=\"https:\/\/calcium-carbonate.epic-powder.com\/fr\/machines\/ball-mill\/\">carbonate de calcium lourd<\/a> Il s&#039;agit d&#039;une charge inorganique obtenue \u00e0 partir de min\u00e9raux carbonat\u00e9s naturels tels que la calcite, le marbre et le calcaire. Chimiquement stable, elle ne r\u00e9agit pas facilement et pr\u00e9sente une bonne stabilit\u00e9 thermique. Elle ne se d\u00e9compose pas en dessous de 400 \u00b0C, pr\u00e9sente une blancheur \u00e9lev\u00e9e, une faible absorption d&#039;huile et un faible indice de r\u00e9fraction. Elle est souple, s\u00e8che, exempte d&#039;eau cristallis\u00e9e, peu dure et peu abrasive, et est non toxique, inodore et sans go\u00fbt. Elle pr\u00e9sente \u00e9galement une bonne dispersibilit\u00e9.<\/p>\n\n\n\n<p>Le carbonate de calcium lourd est largement utilis\u00e9 comme charge dans des industries telles que les carrelages artificiels, le caoutchouc, les plastiques, le papier, les rev\u00eatements, les peintures, les encres, les c\u00e2bles, les mat\u00e9riaux de construction, l&#039;agroalimentaire, les produits pharmaceutiques, les textiles, l&#039;alimentation animale et le dentifrice. En tant que charge, il contribue \u00e0 augmenter le volume des produits et \u00e0 r\u00e9duire les co\u00fbts de production. Dans le caoutchouc, il peut augmenter le volume, am\u00e9liorer la transformabilit\u00e9, fournir un semi-renforcement ou un renforcement, et ajuster la duret\u00e9 du caoutchouc.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/calcium-carbonate.epic-powder.com\/fr\/astra-portfolio\/grinding-and-classifying-system-for-the-production-of-calcium-carbonate\/\"><img fetchpriority=\"high\" decoding=\"async\" width=\"725\" height=\"643\" src=\"https:\/\/calcium-carbonate.epic-powder.com\/wp-content\/uploads\/2025\/04\/heavy-calcium-carbonate.webp\" alt=\"carbonate de calcium lourd\" class=\"wp-image-3085\" srcset=\"https:\/\/calcium-carbonate.epic-powder.com\/wp-content\/uploads\/2025\/04\/heavy-calcium-carbonate.webp 725w, https:\/\/calcium-carbonate.epic-powder.com\/wp-content\/uploads\/2025\/04\/heavy-calcium-carbonate-300x266.webp 300w, https:\/\/calcium-carbonate.epic-powder.com\/wp-content\/uploads\/2025\/04\/heavy-calcium-carbonate-14x12.webp 14w\" sizes=\"(max-width: 725px) 100vw, 725px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"> Les utilisations du carbonate de calcium lourd<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Industrie de production d&#039;\u00e9lectricit\u00e9 \u00e0 partir du charbon<\/h3>\n\n\n\n<p>Dans les centrales \u00e9lectriques au charbon, <a href=\"https:\/\/calcium-carbonate.epic-powder.com\/fr\/ultrafine-air-classifier\/\">carbonate de calcium lourd<\/a> La poudre de carbonate de calcium est utilis\u00e9e pour la d\u00e9sulfuration des fum\u00e9es. Cette op\u00e9ration consiste \u00e0 faire r\u00e9agir du carbonate de calcium lourd avec le dioxyde de soufre produit lors de la combustion du charbon pour former du sulfite de calcium. Ce dernier s&#039;oxyde ensuite en gypse (sulfate de calcium) au contact de l&#039;air, r\u00e9duisant ainsi efficacement les \u00e9missions de dioxyde de soufre jusqu&#039;\u00e0 90%. Le gypse de d\u00e9sulfuration produit peut \u00eatre vendu directement aux cimenteries ou aux fabricants de plaques de pl\u00e2tre. La quantit\u00e9 de poudre de carbonate de calcium utilis\u00e9e est fonction de la teneur en soufre du charbon. En moyenne, une centrale \u00e9lectrique au charbon de 300\u00a0000 kW n\u00e9cessite 40\u00a0000 tonnes de poudre de d\u00e9sulfuration par an.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Industrie du caoutchouc<\/h3>\n\n\n\n<p>Le carbonate de calcium lourd est l&#039;une des charges les plus utilis\u00e9es dans l&#039;industrie du caoutchouc.
