How to get lead-free ceramic powders for 3D printing?

PATENT:

2801240

INVENTION:

Method for obtaining barium-calcium zirconate-titanate powder for additive manufacturing

INVENTOR(S):

Popovich Anatoly Anatolievich, Sufiyarov Vadim Shamilevich, Sotov Anton Vladimirovich, Kantyukov Artem Dmitrievich, Sokolova Victoria Vladislavovna

PATENTEE:

State Atomic Energy Corporation Rosatom (ROSATOM) on behalf of the Russian Federation

PURPOSE:

To produce ceramic powders used in 3D printing.

INNOVATION:

The powder used for 3D printing shall have certain physical and technological properties affecting the process of feeding the material and its uniform distribution during application. The powder material synthesized according to the proposed manufacturing process, obtained by sintering and processing in a low-temperature plasma, has a spherical particle shape. This particle shape is optimal for dense powder filling of the 3D giving chamber volume, subsequent uniform powder supply to the printing area and obtaining a uniform surface of the printed layers, that enables manufacturing products for various electronic devices.

SCOPE
OF APPLICATION:

Electronic sensors, resonators, capacitors, medical and industrial ultrasonic emitters, non-volatile RAM with increased radiation resistance.
