High temperature-resistant marking material, especially ink, for marking surface, especially ceramic surface, e.g. in gas turbine, is aqueous solution of iron nitrate, potassium hexacyanoferrate and ammonia

摘要

Marking material resistant to high temperature, especially ink, for application to surface, especially a ceramic surface, contains 17-20 parts weight iron(III) nitrate nanohydrate, 14-15 parts weight potassium hexacyanoferrate(II) trihydrate, 2.5-10 parts weight 25% ammonia solution and 160-200 parts weight distilled water.
