A miniature high performance flashlamp is disclosed which includes an improved primer material that is more stable in handling during lamp manufacture and further improves performance of the lamp in operation. Said primer material comprises a mixture in percentages by weight of 1-5% sodium chlorate, 1-6% sodium perchlorate, and the balance being zirconium, which mixture can be bonded to form a unitary mass with a polyvinyl pyrrolidone binder. An aqueous solution of the primer material which includes the polyvinyl pyrrolidone binder remains substantially gel-free for long time periods and provides a tough and adherent coating in the lamp.
