Composition for opaque coating, lamp with coating, and method of manufacture |
摘要 |
A composition for the manufacture of an opaque silvery coating on a glass surface is provided. The composition comprises a mixture of at least two metal powders. The metal powder mixture contains carbonyl iron and aluminum, and a carrier liquid for forming a suspension of the metal powder mixture. A method for manufacturing an opaque silvery coating for a lamp having a glass envelope is also provided. In the method, a suspension comprising a mixture of carbonyl iron and aluminum powders in a carrier liquid is applied onto the envelope of the lamp. The suspension is dried, and thereafter the composition remaining from the suspension is burned at a temperature above 500° C. A lamp with a glass envelope and a single layer opaque coating covering at least a part of the glass envelope is also disclosed. The opaque coating comprises 50 to 80 weight % carbonyl iron and 20 to 50 weight % elementary aluminum.
