Calcium carbonate, with the chemical formula CaCO3, is an inorganic compound found in nature as calcite, aragonite, and vaterite. It is a white solid that is insoluble in water but soluble in acid. Widely used as a filler and coating pigment in paper and plastics, calcium carbonate also serves as a primary ingredient in the production of cement and lime. Known for its high purity and chemical stability, it is utilized in pharmaceuticals, food additives, and as a dietary calcium supplement. Its versatility makes it an essential component in various industrial applications.<\/p>","protected":false},"featured_media":3956,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[1144],"product_tag":[],"class_list":{"0":"post-3887","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-chemical-minerals","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product\/3887","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/comments?post=3887"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/media\/3956"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/media?parent=3887"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product_brand?post=3887"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product_cat?post=3887"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product_tag?post=3887"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
