Definitions
- the ingredients are proportioned, mixed uniformly, and subjected to the steps of melting, clarification, homogenization, drawing and annealing to obtain the ion bombardment-resistant microchannel plate skin glass.
- the temperature of the clarifying step is 1400-1600° C., and the time is 2-12 hours;
- the present invention also provides a method for preparing a microchannel plate resistant to ion bombardment, comprising the following steps:
- the acid solution is at least one of nitric acid and hydrochloric acid, the concentration of the acid solution is 0.1 mol % to 30 mol %, the acid solution corrosion time is 10 min to 600 min, and the acid solution is corrosive.
- the temperature is 30°C ⁇ 90°C;
- Na 2 O, K 2 O and Cs 2 O are the outer network oxides of glass.
- Alkali metal ions are easy to move and diffuse in the glass body, which can reduce the viscosity of glass when melted at high temperature, make glass easy to melt, and are good fluxes.
- MgO, BaO and CaO are the external network oxides of glass, and they are both alkaline earth metal oxides, which are beneficial to improve the anti-devitrification ability of glass, adjust the material properties of glass, and improve the thermal processing performance of glass, but the addition amount is too large. As a result, the glass performance is unstable and the phenomenon of phase separation occurs. If the total content of MgO, BaO and CaO is less than 2 mol%, the hot workability of the glass is poor; but if the total content of MgO, BaO and CaO is greater than 8 mol%, the glass is easy to phase separate;
- Sc 2 O 3 is a glass intermediate oxide, and it is also an oxide that controls the ion bombardment resistance of glass. It can improve the hardness, ion bombardment resistance and softening temperature of the glass, and reduce the thermal expansion coefficient of the glass, but when its content exceeds 9 mol%, the Devitrification will occur, the glass stability will deteriorate, and the glass transition temperature and softening temperature are too high, which is not conducive to the subsequent preparation of ion bombardment-resistant glass microchannel plates;
- SrO is an oxide controlled by the ion bombardment resistance of glass, which can improve the hardness and ion bombardment resistance of glass, and reduce the high temperature viscosity of glass. And the thermal expansion coefficient of glass is too large, which is not conducive to the subsequent preparation of ion bombardment-resistant glass microchannel plates;
- ZrO 2 is a glass intermediate oxide, which can improve the viscosity, hardness and chemical stability of glass, and reduce the thermal expansion coefficient of glass. However, when its content exceeds 6mol%, the glass has a narrow glass-forming range and a high softening temperature, which is not conducive to resistance to ion bombardment. The thermoforming and processing of glass is prone to crystallization and phase separation, and the glass performance is unstable;
- the transition temperature of the ion bombardment-resistant microchannel plate cover glass is T g ⁇ 545°C, and the softening temperature is T f ⁇ 627°C.
- the lead oxide is Hongdan or Huangdan
- the barium salt is barium nitrate or barium carbonate
- the potassium salt is potassium carbonate or potassium nitrate
- the scandium salt is scandium nitrate or scandium carbonate
- the strontium The salt is strontium carbonate or strontium nitrate
- the zirconium compound is zirconium oxide or zirconium carbonate or zirconium nitrate
- the molybdenum compound is molybdenum acid or molybdenum trioxide or molybdenum dioxide
- the clarifying agent is Sb 2 O 3 and /or As 2 O 3 .
- the ion bombardment-resistant glass composition provided by the present invention starts from the regulation of glass material components, and proposes to directly introduce special oxides into glass materials to realize the regulation of glass material components, improve the sputtering threshold of glass materials, and greatly improve the resistance of glass materials.
- the characteristics of ion bombardment and the working life of ion bombardment resistance promote the further application of glass materials in time-of-flight mass spectrometers, precision timing instruments, and high-energy ion detection.
- the present invention introduces scandium-containing and/or strontium-containing and/or zirconium-containing and/or molybdenum-containing oxides with high single bond energy into the glass material through the coordination between the components and the adjustment of the dosage.
- Fig. 1 is the ion etching rate comparison diagram of the microchannel plate cover glass provided by the embodiment of the present invention and the comparative example;
- Fig. 2 is the microchannel plate provided by the embodiment of the present invention and the comparative example under 5keV argon ion bombardment, 2.5keV cesium ion bombardment accumulative pick-up charge (working life) contrast curve;
- FIG. 5 is a schematic diagram of the structure of the ion bombardment-resistant microchannel plate of the present invention.
- This embodiment provides an ion bombardment-resistant microchannel plate, which includes a substrate and electrodes disposed on the upper and lower surfaces of the substrate.
