Claims1
A method for producing a molybdenum film for lamp construction, the method comprising:
- roughening at least a part of the molybdenum film by a sandblasting means,
- wherein the sandblasting means contains titanium oxide and at least one of aluminum oxide and quartz sand,
- wherein the proportion by weight of the at least one of aluminum oxide and quartz sand in the sandblasting means is greater than 99 percent by weight, and the proportion by weight of the titanium oxide in the sandblasting means is less than 1 percent by weight, and
- wherein the mean particle size of titanium oxide is less than or equal to 1 micrometer and the mean particle size of that component of the sandblasting means which is formed by at least one of aluminum oxide and quartz sand is less than or equal to 100 micrometers.
