Abstract

A short review of research works carried out in the Institute of Electrophysics UrB RAS on the development of synthesis technology for laser ceramics and the analysis of their characteristics is presented. These ceramics are widely used as active media of solid-state lasers, transparent armor, envelopes of high intensity discharge lamps, heat-resistant and mechanically strong windows etc.

Highlights

Preparation of nanopowders Fabrication technology of laser ceramics can be conveniently divided into three stages: synthesis of nanopowders, their compaction and sintering of compacts
Synthesis and characteristics of highly transparent ceramics It has been shown that the relative density of compacts is practically independent of compaction method and is generally determined by the compaction pressure [2]
Synthesis methods of highly transparent ceramics have been developed on the basis of calcination of nanopowders and compacts (Figure 2)

Summary

Introduction

1. Preparation of nanopowders Fabrication technology of laser ceramics can be conveniently divided into three stages: synthesis of nanopowders, their compaction and sintering of compacts. The main requirements to nanopowders are small particle size, low degree of agglomeration, high purity and cubic phase. We have created the laser synthesis technology of high purity nanopowders with an average particle size of ~10 nm, a size distribution of 5–45 nm (Figure 1) and an output rate up to 80 g/h.
