Abstract

The invention discloses a low-melting-point glass powder and laser-illumination glass ceramic made from the low-melting-point glass powder. A preparing method for the low-melting-point glass powder includes the steps that raw material chemicals are mixed to be even, the mixture is melted for 15 minutes to 90 minutes at the temperature of 300 DEG C to 700 DEG C, and glass liquid is obtained; the glass liquid at the temperature of 300 DEG C to 700 DEG C is quenched and naturally cooled to be at the room temperature, and blocky glass is obtained; the blocky glass is smashed, the smashed glass is put into a ball milling machine and subjected to ball milling, and the low-melting-point glass powder is obtained. The low-melting-point glass powder has the lower glass phase inversion temperature, the glass phase inversion temperature can be adjusted within the temperature range of 200 DEG C to 500 DEG C, the low-melting-point glass powder is suitable for making seal glass and vacuum components and parts and sealing LED, and particularly suitable for making the illumination glass ceramic with a fluorescent powder material, and the illumination glass ceramic is particularly suitable for laser illumination. The glass ceramic is formed and sintered at the low temperature, thermal degradation of fluorescent powder at the high temperature can be effectively avoided, and the laser-illumination glass ceramic has the important application value in the field of laser illumination.

Description

technical field [0001] The technical field of special glass production and manufacture of the present invention, in particular, relates to a low melting point glass powder and the glass ceramics for laser lighting produced therefrom. Background technique [0002] Low-melting point glass refers to a special glass whose glass transition temperature is significantly lower than ordinary glass, and can be widely used as a bonding phase in sealing glass and electronic paste. With the rapid development of the electronics industry, low melting point glass is widely used in the sealing and protection of electronic components and display devices, such as sealing vacuum fluorescent display (VFD), plasma display (PDP) and cathode ray tube (CRT) and other vacuum devices. In terms of LED packaging and its white light adjustment, low-melting glass is needed to replace organics for packaging. Glass ceramics for LED / laser (LD) lighting are also in urgent need of low melting point glass pow...
