anti-bacterial glass ceramics(LATP)

"Anti-bacterial ceramics(LATP)" applies lithium crystallization glass, which is completed by new technology as vector. The ceramics is inorganic antibacterial which supports main part of antibacterial silver ion.

Crystallization glass is given by thermal treatment on special composition glass. The ceramic is made by making use of glass phase separation skillfully. In mechanical strength, hardness, thermal endurance, abrasion resistance, crystallization glass has conspicuous feature in various ceramics materials.

Above all, lithium crystallization glass has continuous sharp pores for passing acid treatment. The glass is superior ceramic materials which performs extremely high ion exchange, PH endurance and stability.

Antibacterial glass ceramics『LATP』is applied material which lithium crystallization glass has superior properties. LATP is very effective antibacterial which has silver ion in high retentions, in very superior persistent effects and light resistance.

This antibacterial is optimum for various processing. It is widely available for antibacterial concerning goods.


  • superior antibacterial
    LATP can perform high antimicrobial activity and widely antimicrobial spectrum by silver effects.
  • high heat resistance
    This is stable even exceeding 1000℃ temperature. (common use 800℃) And, there is no effect for antimicrobial activity.
  • Superior pH resistance
    very superior to acid resistance and alkaline resistance(pH resistance 1~13)
  • High power retentions of silver
    By high exchange performance of ion, There are few silver liquating out even if LATP is doped in any agents.
  • superior light resistance
    Even if LATP is radiated by light in long terms, it maintains vivid white, and there is no discolorations.
  • high safety
    As a result of various tests, there is no problem for safety.
  • high stability
    Under the condition of high humidity, LATP does not absorb moisture, and it maintains stable quality.

measurement effect for Minimum Inhibitory Concentration(MIC)

The result shows Minimum Inhibitory Concentration(MIC) for each bacteria by adding LATP in various culture mediums.
References : MIC shows necessary antibacterial density for preventing bacteria's growing. The lower of value, the higher antimicrobial activity.

test bacteria feature MIC(ppm)
colon bacillus This is bacterial contamination index for food. The bacillus has pathogenicity which causes food poisonings. 62.5
staphylococcus aureus This is toxic type food poisoning bacillus. This bacillus is caused for suppuration. 125
pseudomonas aeruginosa This bacteria breeds in the suppuration part of scars and in the food. 62.5
salmonella It has pathogenicity for humans and animals, and this causes typhoid disease, food poisonings, enteritis. 125
bacillus cereus This bacillus widely distributes in soil, dust, water. This bacillus causes food poisoning, because it is food putrefying bacteria. 125
Saccharomyces This is yeast, which is applied for food fermentation. 125
candida yeast This causes human's Candidiasis as pathogenic yeast. 250
black aspergillus oryzae This bacillus is pathogenicity fungi, such as allergic disease. This is representation for fungi. It grows on fruits and bread. 1000
penicilium(blue fungi) This is food putrefying bacteria. 125

anti-bacterial ball

LATP is printed on the ball, and antibacterial completely extinct germs which causes water putrefying.
And, LATP extinct germs in soluble oil as well.
By excited electron in antibacterial, oxygen molecule absorbed silver ion restores. Thus, reactive oxygen emerges. This reactive oxygen kills germs by directly contacting with germ's cells.


  • Because AG ion combines, antibacterial is being stable and maintaining.
  • By altering compositions, porosity and pore shape of antibacterial can be set optionally.
  • Because average grain diameter is small and specific surface area is large, anti-bacterial ball efficient contact with bacillus.
