The method includes producing a powdery mixture of starting materials. The starting materials comprise ions of the aforementioned composition. At least silicon nitride having a specific surface area greater than or equal to 9 m/g is selected as a starting material and wherein the silicon nitride comprises alpha silicon nitride or is amorphous. The method also includes heat-treating the mixture under a protective gas atmosphere."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for producing a pulverulent precursor material, pulverulent precursor material, and use of pulverulent precursor material","description":"A method can be used for producing a powdery precursor material for an optoelectronic component having a first phase of the following general composition (Ca1-a-b-c-d-eZndMgeSrcBabXa)2Si5N8, wherein X","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9828546","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
