Problems solved by technology

However, compared with glass, transparent ceramics have high strength, high toughness, and better resistance to surface damage; compared with single crystals, transparent ceramics have lower preparation temperatures, shorter production cycles, and are superior in large size and structural design. Single crystal is easier to realize, and the quality of existing transparent ceramic products is poor

Abstract

The invention relates to a transparent ceramic material and a preparation method thereof. The transparent ceramic material comprises, by weight, 65-80 parts of silica, 15-25 parts of alumina, 0.3-0.5part of ferric oxide, 0.5-1 part of calcium oxide, 1-2 parts of potassium oxide, 1-4 parts of lanthana, 3-5 parts of magnesium oxide, 2-5 parts of lithium oxide, 2-4 parts of phosphorus trioxide and 6-8 parts of calcium nitride. The transparent ceramic material has the advantages of high light transmittance, few ceramic production processes, low energy consumption and low cost.

Description

technical field [0001] The invention relates to a ceramic material, in particular to a transparent ceramic material and a preparation method thereof. Background technique [0002] Daily-use ceramic products are easy to wash and keep clean, have good thermal stability and slow heat transfer; in addition, ceramic products have stable chemical properties and are durable, with fewer pores and low water absorption. However, compared with glass, transparent ceramics have high strength, high toughness, and better resistance to surface damage; compared with single crystals, transparent ceramics have lower preparation temperatures, shorter production cycles, and are superior in large size and structural design. Single crystal is easier to realize, and the finished quality of existing transparent ceramic products is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a transparent ceramic material and a preparation meth...
