The diatomite product may comprise sodium flux-calcined diatomite, wherein the diatomite product has a crystalline silica content of less than about 1 wt %, and the diatomite product has a permeability between 0.8 darcy and about 30 darcy. In some embodiments, the diatomite product may be in particulate or powdered form. This disclosure also concerns flux-calcined silica products containing low or non-detectable levels of crystalline silica. Some of these products can be further characterized by high permeabilities and a measurable content of opal-C, a hydrated form of silicon dioxide."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Opaline flux-calcined diatomite products","description":"A diatomite product and method of using such is disclosed.
