Embodiment 1

[0062] Embodiment 1: Manufacture TiO 2 / TiC particles

[0063] After weighing the Ti and C powders at a molar ratio of 1:1, the mixed powder added with 20 wt % silver powder was press-molded into a shape with a diameter of 20 mm and a thickness of 5 mm. One end of the molded body was ignited by arc discharge in the air, and combustion synthesis occurred. After about 5 seconds, ceramic porous particles with a relative density of 50% and a mass of 4.5 g were obtained. The amount of silver contained in the particles was 0.75 g. X-ray diffraction analysis was carried out on the particles, and the results showed that: the particles contained TiO 2 , TiC, Ag and some residual carbon. Moreover, observing the elemental distribution based on EDX, the results show that: even on the surface TiO 2 In any three-dimensional network structure of the TiC layer and the inner TiC layer, silver is uniformly and finely dispersed so as to cover the entire inner wall surface of the continuous p...

Embodiment 2

[0064] Example 2: Manufacture of TiC particles

[0065] After weighing the Ti and C powders at a molar ratio of 1:1, the mixed powder to which 20 wt % of silver powder was added was press-molded into a shape with a diameter of 20 mm and a thickness of 5 mm. If one end of the molded body is ignited with a YAG laser in argon, combustion synthesis will occur, and after about 5 seconds, ceramic porous particles with a relative density of 50% can be obtained. The X-ray diffraction analysis of the particles showed that they were composed of TiC, Ag and some residual carbon, and fine Ag was uniformly dispersed as in Example 1.

Embodiment 3

[0066] Embodiment 3: manufacture TiBN particle

[0067] After weighing Ti and BN powders at a molar ratio of 3:1, the mixed powder to which 20 wt % of silver powder was added was press-molded into a shape with a diameter of 20 mm and a thickness of 5 mm. In argon, a YAG laser is used to ignite one end of the molded body, and combustion synthesis occurs. After about 5 seconds, ceramic porous particles with a relative density of 45% can be obtained. The X-ray diffraction analysis of the particles shows that: TiB, TiB 2 , TiN and Ag, as in Example 1, Ag is uniformly and finely dispersed on the inner wall surface of the porous ceramic pores.

Abstract

The present invention provides a method for obtaining silver ionic water with high concentration by using a simple and convenient process. It is characterized by that said invention relates to a porous ceramic material which is obtained by mixing raw materials containing at least one kind of Ti and Zr. Ag and at least one kind of C.B.BN and B4C and making them undergo the processes of combustion and synthesis and is used for preparing silver ionic water.

Description

technical field [0001] The invention relates to a novel material for generating silver ion water and a method for producing silver ion water using the material. Background technique [0002] As water sterilization methods, for example, 1) heat sterilization, 2) chlorine sterilization, 3) ozone sterilization, 4) ultraviolet sterilization, 5) sterilization by electrolyzed water containing hypochlorous acid, etc. are known. However, these methods have the following problems. [0003] Chlorine disinfection is a widely used method at present, but since the concentration of chlorine in water decreases with time, it is necessary to periodically add chlorine. In addition, in chlorine sterilization, trihalomethane may be produced as a by-product. [0004] Any of heat sterilization, ozone sterilization, ultraviolet sterilization, and electrolyzed water containing hypochlorous acid requires electricity, which is not conducive to cost. [0005] In addition, electrolyzed water contain...
