Embodiment 1

[0020] Step 1: According to the size of the thin laser transparent ceramic green body Φ50×3mm, cut the fluororubber with a thickness of 4mm into two fluororubber discs with a diameter of Φ50;

[0021] Step 2: Wrap the two Φ50×4mm fluororubber discs cut in step 1 on both sides of the Φ50×3mm thin laser transparent ceramic green body to form a Φ50×11mm fluororubber / ceramic green body / fluororubber sandwich configuration, and then put the whole into a plastic bag, and vacuumize the plastic bag;

[0022] Step 3: Put the thin-sheet laser transparent ceramic green body plastic-sealed in step 2 and thickened on both sides with fluororubber into a cold isostatic press, and press at 200 MPa for 5 minutes. Then release the pressure and take it out, cut open the plastic bag, break off the fluororubber on both sides, that is, press to obtain a high-density thin-sheet laser transparent ceramic green body without warping deformation.

Abstract

The invention discloses a cold isostatic pressing forming method of a wafer laser transparent ceramic biscuit with double surfaces thickened by fluorous rubber, the two surfaces of the wafer laser transparent ceramic biscuit are thickened by two pieces of fluorous rubber, and then vacuuming plastic package and isostatic pressing forming are performed. Compared with isostatic pressing forming after direct plastic package of the wafer laser transparent ceramic biscuit, the warping deformation resistance in a plane is integrally improved, the flatness of the wafer laser transparent ceramic biscuit after cold isostatic pressing can be effectively kept, and a qualified wafer laser ceramic biscuit is prepared.

Description

technical field [0001] The invention relates to the technical field of preparation of laser transparent ceramics, more specifically, the invention relates to a cold isostatic pressing forming method of thin-sheet laser transparent ceramic green bodies with double-sided thickening of fluorine rubber. Background technique [0002] Compared with single crystals, laser transparent ceramic materials have three significant advantages: (1) can achieve high-concentration doping and gradient doping of active ions, (2) have higher thermal shock resistance and fracture strength, (3) Optical components of large size and special shape can be prepared; in addition, transparent laser ceramics also have the advantages of low sintering temperature, short preparation cycle, low cost and strong quality controllability. In 1995, Japanese researcher Ikesue and others used high-purity (99.99%) raw materials, applied solid-state reaction and vacuum sintering technology to develop Nd:YAG laser tran...
