Embodiment Construction

[0022] In order to further illustrate the preparation of lead oxide-containing fluorozirconate glass, this embodiment is implemented according to the technical solution of the present invention, and specific implementation methods and processes are given.

[0023] ZrF 4 Take NH 4 ZrF 5 The other fluorides are all high-purity fluoride raw materials. Concrete experimental process has provided the mole percentage composition of the raw material of the embodiment of the present invention 1,2,3,4,5 for table 1, all adopts this preparation process to carry out, carry out in two steps:

[0024] ①Prepare 1000 grams of pure fluoride powder according to a certain ratio. After fully mixing, put it into a platinum crucible. Put the crucible into the furnace and raise the temperature to 850°C for 30 minutes. After fully melting, take it out and pour it directly on the template On, the clinker of pure fluorozirconate is obtained;

[0025] ② Weigh 1000 grams of clinker, put it back into ...

Abstract

The invention discloses lead oxide containing fluoroziconate glass and a preparation method thereof. The glass is composed of the following components in mole percentage: 2-15% of PbO, 45-60% of ZrF4, 25-35% of BaF2, and 5-11% of LaF3, AlF3 and YF3. The glass has high transmittance from near ultraviolet waveband to intermediate infrared waveband. Compared with the existing fluoride glass, the lead oxide containing fluoroziconate glass has better glass forming performance, and can significantly improve the devitrification in the process of fiber-optical drawing, therefore, the fluoroziconate glass can be used for manufacturing large-sized infrared materials.

Description

technical field [0001] The invention relates to fluorozirconate glass, in particular to a fluorozirconate glass containing lead oxide and a preparation method thereof. Background technique [0002] Fluoride glass has a wide range of optical applications, such as the preparation of ultra-low loss optical fibers, optical waveguides, optical fiber amplifiers, etc. The successful development of bulk fluoride glasses has brought increasing attention to the application of these materials as volume infrared optics. ZrF 4 Fluoride glass, which is the main component of glass, is called fluorozirconate glass. Compared with other fluoride glasses, fluorozirconate glass not only has good formability, but also has excellent optical properties, and is the main fluoride glass matrix for preparing fluoride optical fibers. Although many new systems have been developed, almost all of them are prone to devitrification. Poulain reported that typical fluorozirconate glasses include 56ZrF 4 ...
