Alumina / zirconia ceramics containing Al2O3 in an amount of not less than 65 mass % and ZrO2 in an amount of 4 to 34 mass %, and further containing TiO2, MgO and SiO2. The ceramics effectively suppresses the growth of shape isotropic particles of alumina, suppresses the growth of zirconia particles, and has a high strength and a high hardness. Besides, the ceramics containing SrO features a high fracture toughness.

Unique abrasive and / or thickening materials that are in situ generated compositions of precipitated silicas and silica gels are provided. Such compositions exhibit different beneficial characteristics depending on the structure of the composite in situ generated material. With low structured composites (as measured via linseed oil absorption levels from 40 to 100 ml oil absorbed / 100 g composite), simultaneously high pellicle film cleaning properties and moderate dentin abrasion levels are possible in order to accord the user a dentifrice that effectively cleans tooth surfaces without detrimentally abrading such surfaces. Increased amounts of high structure composite materials tend to accord greater viscosity build and thickening benefits together with such desirable abrasion and cleaning properties, albeit to a lesser extent than for the low structure types. Thus, mid-range cleaning materials will exhibit oil absorption levels from an excess of 100 to 150, and high thickening / low abrasion composite exhibit oil absorption properties in excess of 150. Such an in situ, simultaneously produced precipitated silica / silica gel combination provides such unexpectedly effective low abrasion and high cleaning capability and different thickening characteristics as compared to physical mixtures of such components. Encompassed within this invention is a unique method for making such gel / precipitated silica composite materials for such a purpose, as well as the different materials within the structure ranges described above and dentifrices comprising such.

A chain is constructed by alternately connecting a pair of outer link plates connected together with pins and a pair of inner link plates connected together with bushings into which adjacent pins of adjacent pairs of outer link plates are inserted. On the outer and inner surfaces of component parts of the chain, a lubricant composition for chains containing 95% to 80% by mass of a lubricant which is liquid at room temperature and 5% to 20% by mass of a wax which is solid at room temperature and having a consistency of from 60 to 475 and a dropping point of from 60° C. to 120° C., is adhered.
