A kind of glass ceramics with potassium feldspar as main material and preparation method thereof

Abstract

The invention discloses a microcrystalline glass using potash feldspar as a main material, which is prepared from the following raw materials in parts by weight: 56-61 parts of potash feldspar, 19-25 parts of albite, 10-14 parts of silica powder, 8-13 parts of silicon dioxide, 8-10 parts of calcium oxide, 8.5-10 parts of sodium carbonate, 6.5-8 parts of calcium fluoride, 6-8 parts of table salt, 6-7 parts of potassium oxide, 5-7 parts of zinc oxide, 4.5-6 parts of aluminum oxide, 1-2 parts of sodium oxide, 2.5-3 parts of magnesium oxide, 3.5-4 parts of wood coal, 2-3 parts of gypsum, 3.2-5 parts of boron oxide, 2-3 parts of talcum powder, 2-4 parts of borax, 1.5-2 parts of lithium oxide, 2.3-3 parts of modified plant ash, 0.13-0.2 part of nickel oxide, 0.6-0.7 part of titanium dioxide, 0.8-1.2 parts of antimony trioxide and 0.3-0.4 part of potash feldspar. The microcrystalline glass disclosed by the invention has the advantages of favorable planarity, high mechanical strength, high hardness, favorable heat resistance, favorable bending strength, favorable corrosion resistance and favorable wear resistance; and the product can be prepared into various tubes and plates, and can be widely used as architectural wear-resistant corrosion-resistant materials and architectural decoration materials.

Description

technical field [0001] The invention mainly relates to a glass-ceramic and a preparation method thereof, in particular to a glass-ceramic with potassium feldspar as the main material and a preparation method thereof. Background technique [0002] Glass-ceramic, also known as glass-ceramic, is a new type of material developed by combining glass and ceramic technology.

AI Technical Summary

Problems solved by technology

Because glass-ceramics can use ore, industrial tailings, metallurgical slag, potassium feldspar, coal gangue, etc. as the main raw materials for production, and there is no pollution in the production process, and the product itself has no radioactive pollution, so it is also called an environmentally friendly product or green material. , the surface layer and inner layer of traditionally produced glass-ceramics often have a large number of technological pores, and the flexural strength and water resistance are not strong, which limits the application field of glass-ceramics
