Description
Technical field
It is specifically a kind of to be used to prepare solid phase converter glass microsphere the present invention relates to angular acceleration transducer field
Glass formula.
Background technology
With the development of science and technology, in war industry, the control of most of moving object of aerospace field and prison
In examining system, angular displacement, the information of angular speed are not only needed, with greater need for the relevant information of angular acceleration.With industrial automatic control
Technology processed develops rapidly, and the application demand of angular acceleration transducer becomes more and more.
The structure of Pendular ring type angular acceleration transducer is mainly made up of datum plate, amplifying circuit and pendular ring, and wherein pendular ring is
Core, it is made up of fluid chamber, liquid, electrode and solid phase converter.Wherein solid phase converter is porous network structure, when
Pendular ring is in motion process, and a series of change can occur for " Gu-liquid " interface inside and outside switching device, the electricity formed
Potential difference is accessed after amplifying circuit is amplified by the electrode of pendular ring terminal and exported, so solid phase converter is to influence whole angle to add
An important factor for velocity sensor performance.
Converter needs strict softening point and the coefficient of expansion, and component requirements with glass microsphere in Pendular ring type sensor
Compare strictly, the softening point and the coefficient of expansion of glass microsphere and the softening point and the coefficient of expansion of pendular ring need to be mutually matched, and otherwise can
Cause pendular ring leakage or burst.Further, since frit in melting process caused gaseous product in glass system
Solubility is different, and the clarifying effect of glass and its solubility directly affect the performance after glass balling-up, so as to influence
The density of glass microsphere and solid rate, directly affect the performance of converter, and glass composition directly affects glass microsphere after sintering
One of key of energy.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of glass for being used to prepare solid phase converter glass microsphere
Formula, the average line style coefficient of expansion that the softening point of the glass of the formula can reach in the range of 740 ± 20 DEG C, 0~300 DEG C can
Up to (80 ± 5) × 10-7, using the formula glass production glass microsphere prepare solid phase converter can well with pendular ring
Glass tube matched expansion coefficient.
In order to solve the above technical problems, the invention provides a kind of glass for being used to prepare solid phase converter glass microsphere
Formula, including following components in percentage by weight：Silica (SiO2) 60%~65%, boric acid (B2O3) 0.5%~1.5%,
