This is especially true for fluorspar (CaF\u2082), which finds critical applications across metallurgy, chemical, glass, ceramics, and advanced technologies\u2014each demanding different purity levels and strict quality control.<br>Industrial buyers worldwide consider not only the CaF\u2082 purity but also compliance with recognized international standards as prerequisites for trade. Without standardization, even high-quality fluorspar risks losing access to lucrative export markets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article reviews how global fluorspar purity standards are defined, their differences, and the technical and quality requirements Iranian producers must meet to compete internationally.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">                  \u200c         <\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\"><strong>Fluorspar Grade Classification in Global Standards<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Fluorspar is commonly classified by CaF\u2082 content into three main grades, with additional criteria such as particle size, impurity levels, color, and moisture influencing categorization. Understanding these grades and associated standards is essential for producers, exporters, and industrial buyers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\"><strong>Metallurgical Grade<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CaF\u2082 Purity: Typically 60% to 85%<\/li>\n\n\n\n<li>Use: Flux in steel, foundry, and cast iron industries<\/li>\n\n\n\n<li><strong>Features: <\/strong>Darker color, coarse or broken particles, relatively low cost, tolerates higher impurities (e.g., SiO\u2082, Fe)<\/li>\n\n\n\n<li>Mainly consumed domestically or in non-critical industrial applications.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\"><strong>Ceramic Grade<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CaF\u2082 Purity: Approximately 85% to 95%<\/li>\n\n\n\n<li>Use: Tiles, porcelain, glass, glaze, industrial ceramics<\/li>\n\n\n\n<li>Features: Lighter color (white to light gray), controlled particle size, stricter limits on optical and metallic impurities<\/li>\n\n\n\n<li>Competitively exported with tight impurity control and uniform appearance.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\"><strong>Acid Grade<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CaF\u2082 Purity: Above 97%<\/li>\n\n\n\n<li>Use: Hydrofluoric acid (HF) production, chemical, petrochemical, optical, energy sectors<\/li>\n\n\n\n<li>Features: Very high purity, minimal impurities (&lt;1%), fine uniform particles, slightly bluish-white color, strict analysis and documentation<\/li>\n\n\n\n<li>Highest value, most sensitive, and most demanded grade globally.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">               \u200c\u200c\u200c\u200c          <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" style=\"font-size:20px\"><strong>Complementary Criteria in Global Standards<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond CaF\u2082 purity, international standards commonly regulate:<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Parameter<\/strong><\/td><td><strong>Importance<\/strong><\/td><\/tr><tr><td><strong>SiO\u2082 (Silica)<\/strong><\/td><td>Lower is better, critical in acid grade<\/td><\/tr><tr><td><strong>Fe\u2082O\u2083 (Iron oxide)<\/strong><\/td><td>Negatively affects color and optical properties<\/td><\/tr><tr><td><strong>Pb, As, S (Heavy metals)<\/strong><\/td><td>Restricted or banned in sensitive industries<\/td><\/tr><tr><td><strong><strong>Moisture<\/strong><\/strong><\/td><td>Usually must not exceed ~0.5%<\/td><\/tr><tr><td><strong>Particle Size<\/strong><\/td><td>Must meet industry-specific ranges<\/td><\/tr><tr><td><strong>Color and Visual Uniformity<\/strong><\/td><td>Crucial for export markets<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The classification of fluorspar grades according to global standards is not limited to purity percentage alone; it also includes a combination of technical and visual parameters that directly affect the price, application, and market demand.
