This is due to the increase in the surface-to-mass ratio of the particles, which increases the surface area per unit mass, which improves the performance of the particles, decreases the melting point of the particles, and changes the properties of the particles. Has different properties.

The sol-gel method is expensive to manufacture and difficult to mass-produce. The reverse-phase microemulsion method makes it easy to control the particle size, shape, and size distribution, but the manufacturing process is very complicated and it is not practical.

본 발명이 이루고자하는 기술적 과제는 다음의 3가지이다.The technical problem to be achieved by the present invention is the following three.

①경제적인 미세 은(Ag)입자의 함유 도자기 조성물 제조① Manufacture of ceramic composition containing economical fine silver (Ag) particles

Conventional coarse silver (Ag) particles (1 micron or more) containing porcelain composition manufacturing technology is very disadvantageous in terms of mass production and cost, but the present invention is simple in the manufacturing process, mass production is possible and inexpensive in terms of cost.

②효과적인 미세은(Ag) 입자의 활용② Utilization of effective fine silver (Ag) particles

위의 방법으로 제조된 미세 은(Ag)입자들은 도자기 조성물내에 분산시켜 항균 및 살균목적, 연마제, 의약용 목적으로 이용시 도자기 조성물의 항균 성능이 극대화된다.Fine silver (Ag) particles prepared by the above method is dispersed in the porcelain composition to maximize the antimicrobial performance of the porcelain composition when used for antibacterial and sterilization purposes, abrasives, medical purposes.

이렇게 제조된 미세 은(Ag)입자는 크기분포가 균일하고 미세함으로 도자기 조성물 제조시 도자기 원료 또는 원료 성형체에 스프레이(Spray) 방식으로 분산시켜 혼합하거나 원료를 하소한 후에 스프레이(Spray) 또는 적심(Dipping)방식으로 혼합하여 소성한다. 이렇게 제조된 도자기 조성물은 항균 및 살균 목적으로 이용시 항균효과가 극대화되고 미세 은(Ag)입자의 성능을 장시간 유지시킨다Thus, the fine silver (Ag) particles are uniform in size distribution and finely dispersed in the ceramic material or raw material molded body in the spray method by mixing or calcining the raw material after spraying or dipping. ) And mix and fire. The porcelain composition thus prepared maximizes the antibacterial effect when used for antibacterial and sterilization purposes and maintains the performance of fine silver (Ag) particles for a long time.
