Abstract

L'invention concerne un procédé de production efficace d'un bactéricide possédant un excellent pouvoir bactéricide sans libérer de substance dangereuse pour la santé des animaux ou des plantes. Ce bactéricide est produit par un procédé qui consiste à traiter thermiquement une substance contenant un constituant calcique à une température d'au moins 650 °C ou inférieure au point de fusion de ladite substance, pendant au moins deux heures. Le procédé consiste ensuite à broyer la substance traitée thermiquement contenant le constituant calcique pour la réduire en une poudre présentant un diamètre moyen des particules d'au plus 10 νm. Ledit traitement thermique confère son pouvoir bactéricide à la substance contenant le constituant calcique. Le broyage de la substance traitée thermiquement contenant le constituant calcique augmente une surface de contact avec les bactéries, ce qui assure un effet bactéricide plus important. De préférence, l'étape de prébroyage est accomplie en vue de réduire la substance contenant le constituant calcique en grains présentant un diamètre moyen des grains de 10 à 20 mm, avant l'étape de traitement thermique. Le prébroyage de la substance permet de réaliser un traitement thermique uniforme de la surface à l'intérieur d'un grain prébroyé et cela, dans
