Abstract
The invention discloses a kind of germanate glass for infrared rays and preparation method thereof, the glass for infrared rays by following weight percentage component: 5-45%GeO2, 15-30%Al2O3, 5-35%CaO, 0-5%SrO, 1-15%BaO, 1-5%BaF2, 0-5%Bi2O3, 1-5%TiO2, 6-16%La2O3, 1-20%Gd2O3.The present invention also provides a kind of preparation methods of germanate glass for infrared rays, comprising the following steps: preparing glass charge: glass raw material being carried out high temperature sintering dehydration before ingredient, then weighs each raw material according to the weight percent of each component；Glass melting: mixture is put into platinum crucible, is then placed in 1400 DEG C -1600 DEG C of glass furnace and is heated 1~3 hour；Chilling molding: after glass melting is uniform, the glass metal after melting being poured into preheated mold and pour into defined specification, be then placed in annealing furnace and make annealing treatment, and then cools to room temperature with the furnace, cooling to obtain germanate glass for infrared rays material.Preparation method of the present invention is simple, prepared germanate glass for infrared rays function admirable.
Description
Technical field
The present invention relates to glass for infrared rays and its preparation technical field, in particular to a kind of germanate glass for infrared rays and its
Preparation method.
Background technique
Infrared ray is electromagnetic wave of the wave-length coverage between microwave and visible wavelength range, and wave-length coverage is at 0.75 μm
It is the wavelength non-visible light longer than red light wavelength between~500 μm, there is fuel factor, invisible, strong through cloud and mist ability
The features such as.Infrared ray can be divided into three parts, i.e. near infrared ray (wave-length coverage is 0.75 μm~2.5 μm), middle infrared ray (wavelength model
Enclose is 2.5 μm~25 μm), far infrared (wave-length coverage is 25 μm~500 μm).Infrared ray is in electronic communication, remote sensing test, work
Industry detection, environmental monitoring, biologic medical, defense military etc. all have been widely used.
The research emphasis of domestic and international infrared optical material is the material of 1~5 mu m waveband, because of the infrared ray of 1~5 mu m waveband
Decaying in an atmosphere is minimum.And in order to improve infrared monitoring induction range, saturating infra-red material is preferably processed into dome shape
Shape.By taking fire alarm as an example, fire sensor passes through infrared ray of the saturating infrared cover for 1.0-5.0 mum wavelength of dome shape
With good transmitance, the places such as cinema theater, stadiums, Conference Room, tunnel culvert install fire-alarm with
The generation of fire is perceived, is mainly perceived by the infrared ray of flame emission, reaction speed is fast, especially in heavy construction
Interior broad space, the induction of infrared ray than smog and combustion products induction faster, it is more reliable.Flame is along with combustion
The red-hot heat source for burning reaction and generating can emit infrared light since the addition of cigarette and combustion products becomes extremely complex, and
In the luminous energy emitted in flame, the luminous of infra-red range is that flame is distinctive, and therefore, therefore, saturating infra-red material must be to fire
The distinctive infrared ray of flame has high sensitivity, and the sensing range of IR wavelength is just in 1.0-5.0 mu m waveband range；It is other
If missile guidance outer cover is also with identical principle, manufactures nose of missile dome material and require saturating infra-red material performance good
It is good, 800 DEG C of high temperature are resistant to, and have good spalling resistance performance, this is because head material is rubbed by air-flow when MISSILE LAUNCHING
It wipes, in a very short period of time surface temperature can be increased suddenly, and require material not rupture, is indeformable, therefore infrared material thoroughly
Material should have good thermal shock resistance, in addition, in order to adapt to field environment, more require infra-red material chemical stability and
Mechanical strength is all fine.
Saturating infrared cover material currently used for infrared ray in 1 μm~5 μm mainly has the materials such as ZnS, spinelle and sapphire
Material, although these materials have advantage in certain aspect of performance, it is right to be also possible that applied to general material of infrared window
Various deficiencies are still had in terms of the infrared cover of high-speed aircraft, thermal shock resistance.
Infrared transmittivity such as ZnS is high, and is readily processible to required window or mask body shape, but ZnS material sheet
Stature matter is very soft, is extremely easy to be worn at typical condition, so that its application range and service life are restricted, in reality
Border can be improved in the method for protective film coating, but itself and windage in the high-speed flight of guided missile or rocket
The high temperature of generation will lead to plated film layer and fall off.
Spinelle (mineral that main component is magnesium aluminum oxide composition) infrared transmission performance is slightly worse compared with ZnS, in 5 μm of waves
Strong point, which exists, to be partially absorbed, but its hardness is more than ten times of ZnS, and fracture toughness is higher, so thermal shock resistance is strong, but
It is spinelle forming difficulty, is processed into window or cover is difficult, material and processing cost is all very high.
