Since 20 more years, the domestic and foreign scientists have developed unceasingly new materials and equipments for water disinfection and purification processing. Such as barreled water popularized family, and quite popular dual water supply and water purifiers, etc new products in the recent years. These products have a good improvement to the purification of drinking water. But, when these products disinfect and purify water, often exist the objection, such as bacterium exceed the standard, the pure water is "too pure", "the healthy water" is not health, etc, which have brought many hidden trouble for the general consumers' health.

Facing the status of our drinking water, BONA well timed researched and developed healthy ceramic material which can have do series processing of antibacterium , purification, mineralization and activation to drinking water. Now BONA has healthy ceramic filter, healthy ceramic ball and healthy ceramic piece, etc. .

1 Brief introduction of healthy ceramic ball
1.1 Material Component of healthy ceramic ball
BONA Healthy ceramic material is made of many kinds of natural polar mineral material and multifunctional healthy ceramic material through compound process and high temperature sinter.
After massive experiments and optimized design, we have confirmed the best chemical composition of healthy ceramic material as the following (Weight ratio, %)
SiO 2 : 66.23; Al 2 O 3 : 11.11; Fe 2 O 3 : 1.57; Na2O: 1.80; K 2 O: 4.78; MgO: 2.32; CaO: 5.98; ZnO: 4.38; B 2 O 3 : 1.08; Rare earth, additive: amount of the remainder
1.2 The classification of healthy ceramic ball
