METHOD OF MAKING CERAMIC TIPS FOR FIBRE-OPTIC CONNECTORS Russian patent published in 2014 - IPC C04B35/48 B28B1/24 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of making precision fibre-optic components and specifically to the technology of making tips for fibre-optic connectors. The method of making ceramic tips for fibre-optic connectors involves preparing a mixture of fine zirconium dioxide powder with binder, moulding a workpiece of the tip by pressure moulding using a cylindrical mould with a cylindrical metal insert which forms an inner through hole, removing the workpiece of the tip from the mould, removing the insert, calcining and sintering the workpiece, followed by mechanical treatment of the surface of the workpiece. The workpiece is sintered with the cylindrical metal insert, which forms an inner through hole, in an inert medium, and the cylindrical metal insert, which forms an inner through hole, is removed from the workpiece after sintering by drawing at subzero temperature, wherein the inert is a wire element whose cross-section is identical to that of the optical fibre.

EFFECT: ensuring stable dimensions of the tip and preventing further machining of the inner diameter of the tip to the required size.
