Abstract
The present invention relates to sealing glass without lead. The present invention is a glass body which is formed after vanadium oxide (V2O5), phosphorus oxide (P2O5) and antimony oxide (Sb2O3) are mutually mixed to be melted and cooled. The present invention comprises by weight percentage: 30% to 70% of vanadium oxide (V2O5), 10%to 30% of phosphorus oxide (P2O5), and 0.5% to 25% of antimony oxide (Sb2O3). A preparation method of the present invention at least comprises: weighing the vanadium oxide (V2O5), the phosphorus oxide (P2O5) and the antimony oxide (Sb2O3) by the weight percentage, and then, fully mixing the components so that a mixed material is prepared; melting the mixed material for 2 to 3 hours at the temperature of 800 DEG C to 1200 DEG C; cooling and solidifying melted liquid. The sealing glass without lead, which is supplied by the present invention, can directly seal a vacuum glass product needing sealing (such as VFD, PDP, CRT, etc.) in a nontoxicity and no pollution mode and can adjust component mixture ratio according to different temperature and thermal expansion characteristics of the sealed product so that the sealing requirements for various materials is met.
Description
Technical field
The present invention relates to a kind of barium crown sealed glass, particularly a kind of not leaded and have low melting point, low expansion character, can be used for various vacuum glass devices are carried out the manufacture method of glass and this glass of sealing-in.
Background technology
In the production process of vacuum glass goods, need have usually than low melting point and more low-expansion glass or glass powder as seal, sealing materials.
Before this, a large amount of seal glasses that use all are the low-melting point sealing glass of plumbous zinc system (PbO-ZnO), though this glass can satisfy the sealing-in requirement of vacuum glass device preferably, but because plumbous influence to environment and human health, therefore, for providing lead-free sealing glass material, vacuum glass product manufacturing become the problem that must solve as early as possible.
At present, existing in the world seal glass and glass powder have following several usually.
The spy of Hitachi opens flat 2-267137 and discloses a class vanadium oxide (V
2O
5) be glass.The coefficient of expansion of this glass is 90 * 10
-7/ ℃ below, sealing temperature is below 400 ℃, it mainly acts on is to prepare the coefficient of expansion in (30~45) * 10
-7/ ℃ about sealing glass powder.But in this product, plumbous oxide is the neccessary composition as component, thereby can't satisfy unleaded requirement, simultaneously, owing to also contain the oxide compound of hypertoxic thallium (Tl) in this product, and the price of Tl is comparatively expensive, therefore, this glass and uneconomical again with the i.e. not environmental protection of glass powder of this glass making can only be used for special vacuum glass goods.
In addition, the fair 5-85490 in flat Hitachi proposes a class V
2O
5-Tl
2O-TeO
2-R
2O glass, main component are V
2O
5, P
2O
5, contain the oxide compound of sodium, potassium, rubidium, caesium, tellurium etc. simultaneously, can finish 400~500 ℃ sealing-in, the coefficient of expansion (70~130) * 10
-7/ ℃.Though not leaded in the composition of this glass, owing to contain a certain amount of highly toxic substance thallium oxide (TlO
2) and noble metal tellurium (Te) etc., thereby cost is very high.It mainly is used as the seal, sealing materials and the magnetic gap compaction material of high-performance magnetic head.
Have, the U.S. Pat 2002019303 of NIPPON electronic glass application has proposed a kind of P again
2O
5The sealing glass powder of-SnO-ZnO, 430~500 ℃ of sealing temperatures.But because this glass powder contains a large amount of SnO, and oxidation easily, need under reducing atmosphere conditions such as complete nitrogen, produce and sealing-in, thereby be difficult to carry out industrialization and postorder sealing-in application, simultaneously, SnO is also relatively more expensive.Owing to have above defective, make the use of this glass be subjected to bigger restriction.
In the research of barium crown sealed glass, adopt bismuth oxide (Bi in addition
2O
3) substitute the bismuth glass of plumbous oxide.But, owing to use bismuth oxide, make manufacturing cost increase greatly, and the coefficient of expansion of this glass is too big, be difficult to regulate the requirement that reaches with the sealing-in that is complementary by the coefficient of expansion of sealing-in product in actual applications.
Summary of the invention
Main purpose of the present invention is to provide a kind of barium crown sealed glass at the defective that contains lead or thallium or noble metal and oxide compound thereof in the above-mentioned seal glass, this seal glass does not only contain lead, and do not contain highly toxic substances such as tellurium or thallium, do not contain noble metal and oxide compound thereof simultaneously yet.
Another object of the present invention is to provide a kind of method that is used to make above-mentioned barium crown sealed glass.
The objective of the invention is to be achieved through the following technical solutions:
A kind of barium crown sealed glass, it is by vanadium oxide (V at least
2O
5), phosphorus oxide (P
2O
5) and weisspiessglanz (Sb
2O
3) mix the vitreum of after the fusion cooling, being formed mutually; Described vanadium oxide (V
2O
5) weight percent be 30%-70%; Described phosphorus oxide (P
2O
5) weight percent be 21%-30%; Described weisspiessglanz (Sb
2O
3) weight percent be 0.5%-25%; Also comprise bismuth oxide Bi in the described vitreum
2O
3, its weight percent is 0.5%-4.5%.
In above-mentioned barium crown sealed glass, can also sneak into stabilization component and halogenide according to specific requirement.
The manufacture method of above-mentioned barium crown sealed glass may further comprise the steps at least:
Step 1: take by weighing vanadium oxide (V according to weight percent
2O
5), phosphorus oxide (P
2O
5), bismuth oxide Bi
2O
3And weisspiessglanz (Sb
2O
3) after carry out thorough mixing, make compound;
Step 2: described compound was melted 2-3 hour down at 800 ℃~1200 ℃;
Step 3: the liquid to fusing in the step 2 carries out cooling curing, makes vitreum.
Vitreum can be made tabular, column or directly make powdery according to sealing-in product characteristics and requirement.
Barium crown sealed glass provided by the present invention can directly carry out nontoxic, pollution-free sealing-in to the vacuum glass goods (as VFD, PDP, CRT etc.) that need sealing-in, also can be according to difference by the temperature of sealing-in product, thermal expansion character, adjustment set of dispense ratio satisfies the sealing-in requirement of multiple differing materials.The requirement of for example various glass, pottery, intermetallic and mutual sealing-in.
