Embodiment 1

[0031] Sample 1: (P 2 o 5 ) 0.56 (SiO 2 ) 0.1 (GeO 2 ) 0.05 (Al 2 o 3 ) 0.20 (Li 2 O) 0.10 (Cu 2 O) 0.0025 (Fe 2 o 3 ) 0.0025

[0032] The raw material used is NH 4 h 2 PO 4 , SiO 2 、GeO 2 、Al 2 o 3 , Li 2 CO 3 、Cu 2 O and Fe 2 o 3 . After the above raw materials are pre-mixed evenly by grinding, they are heated to 1450°C at 5°C / min in an air atmosphere in an electric furnace, taken out immediately, poured on a copper plate at 290°C for quenching, and then annealed at 290°C for 3 hours to obtain sample 1, sample 1 The UV-Vis absorption spectrum of figure 1 It can be seen that sample 1 has no obvious absorption in the visible light region and only has certain absorption in the red light region (660-760nm). Infrared light has strong absorption and can be used in occasions that do not require high quality of natural light.

Embodiment 2

[0034] Sample 2: (P 2 o 5 ) 0.56 (SiO 2 ) 0.1 (GeO 2 ) 0.05 (Al 2 o 3 ) 0.20 (Li 2 O) 0.10 (Cu 2 O) 0.0025 (Fe 2 o 3 ) 0.005

[0035] The raw material used is NH 4 h 2 PO 4 , SiO 2 、GeO 2 、Al 2 o 3 , Li 2 CO 3 、Cu 2 O, Fe 2 o 3 ; After the raw materials are pre-mixed evenly by grinding, they are heated to 1450°C at 5°C / min in an air atmosphere in an electric furnace, taken out immediately, poured on a copper plate at 290°C for quenching, and then annealed at 290°C for 3 hours to obtain sample 2; sample 2 The UV-Vis absorption spectrum of figure 2It can be seen that sample 2 has no obvious absorption in the visible light region, but has certain absorption in the red light region of 700-760 nm, and sample 2 is transparent and bluish. Sample 2 has a strong absorption of ultraviolet light of 200-365nm, and a strong absorption of near-infrared light of 760-1640nm. It can be seen that sample 2 can be used in almost all occasions that require energy-savi...

Embodiment 3

[0037] Sample 3: (P 2 o 5 ) 0.56 (SiO 2 ) 0.1 (GeO 2 ) 0.05 (Al 2 o 3 ) 0.20 (Li 2 O) 0.10 (TiO 2 ) 0.01 (Fe 2 o 3 ) 0.005

[0038] The raw material used is NH 4 h 2 PO 4 , SiO 2 、GeO 2 、Al 2 o 3 , Li 2 CO 3 , Fe 2 o 3 、TiO 2 . After the raw materials were ground and pre-mixed uniformly, they were heated to 1450°C at 5°C / min in an air atmosphere in an electric furnace and immediately taken out, poured on a copper plate at 290°C for quenching, and then annealed at 290°C for 3 hours to obtain sample 3; UV-Vis absorption spectrum, such as image 3 As shown, sample 3 has no obvious absorption in the visible light region and only has certain absorption in the range of 390-590nm. The sample is transparent but slightly brownish. Sample 3 has a strong absorption of ultraviolet light of 200-365nm, and a strong absorption of near-infrared light of 900-2000nm, so sample 3 can be used in almost all occasions that require energy-saving glass.

Abstract

The invention belongs to the technical field of glass preparation, and particularly relates to novel transition metal ion-doped energy-saving glass and a preparation method thereof. The novel transition metal ion-doped energy-saving glass is (P2O5)0.56(SiO2)0.1(GeO2)0.05(Al2O3)0.20(Li2O)0.10(Cu2O)x(Fe2O3)y(TiO2)z, wherein x is 0 to 0.001; y is 0 to 0.005; z is 0 to 0.001; at least two of x, y andz are not simultaneously zero. The invention further provides the preparation method of the novel transition metal ion-doped energy-saving glass. The preparation method comprises the following steps of step 1, mixing NH4H2PO4, SiO2, GeO2, Al2O3, Li2CO3, Cu2O, Fe2O3 and TiO2, and heating, so as to obtain a melted material; step 2, quenching the melted material, and annealing, so as to obtain the novel transition metal ion-doped energy-saving glass. The novel transition metal ion-doped energy-saving glass and the preparation method provided by the invention can effectively solve the technical problem of failure to simultaneously reach heat isolation property and safety in the existing energy-saving glass.

Description

technical field [0001] The invention belongs to the technical field of glass preparation, and in particular relates to a novel transition metal ion-doped energy-saving glass and a preparation method thereof. Background technique [0002] Due to its good permeability, glass is an excellent material, which has the function of light transmission and wind and snow protection, and is widely used in modern buildings, automobiles and other equipment. Modern multi-functional and large-scale buildings and automobiles also put forward new requirements for glass materials, especially for safety, heat insulation, and aesthetics. With the development of modern science and technology, various glasses with unique functions have come out one after another. Among them, energy-saving glass has been widely used in the field of building curtain walls due to its beautiful and generous color, good texture and excellent energy-saving characteristics. [0003] However, the main energy-saving princ...
