Ceramic Tile Mohs Scale

This is a scale of hardness ranging from 1 talc to 10 diamond used to determine a material s scratch resistance.

Ceramic tile mohs scale.

The mohs scale is based on a relative value of 1 10. Hardness of some common items on the mohs scale. What is mohs rating for tile. Ceramic tile scratch hardness is usually determined by the method set out in the old en 101 standard ceramic tiles.

With 1 being the softest and 10 being the hardest. Determinotion of scratch hardness of surface according to mohs though not included in the new iso standards on ceramic tiles the test has not been replaced by any other scratch hardness measuring method and still finds widespread use. Fringernails are given as 2 penny is given as 3 knife blade is given as 5 window glass is given as 5 5 and steel file is given as 6 5. To give the consumer a relative measurement of scratch resistance of tile and stone manufacturers and suppliers use the moh s hardness scale.

Most ceramic tile manufacturers use the mohs scale to test the scratch and abrasion resistance of the glaze that is applied to the tile. Pingxiang chemshun ceramics co ltd is a professional manufacturer of 92 95 alumina ceramics zta ceramics with the good character of strong hardness 9 mohs hardness scale strong abrasion resistance and impact corrosion resistance excellent heat resistance up to 1500centi degree and it s easy to install. The mohs scale of mineral hardness m oʊ z is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Result mohs hardness of tiles is given in table 1 and is classi fied into two groups by the scale.

The pei scale has ranked different ceramic tile types into five separate classes based on the hardness of the tile. There is not a clear boundarybetweensoftandhardtiles butthesofttypehas a value of 2 3 and the hard type has a value of 5 6 10 the vickers hardness of tiles under different loads is shown in fig. Created in 1812 by german geologist and mineralogist friedrich mohs it is one of several definitions of hardness in materials science some of which are more quantitative. Porcelain tile often has a rating of 7 8 or 9 while other less scratch resistant non porcelain tiles are rated at 5 or 6.

Moh s scale will list about ten minerals and they are talc gypsum calcite fluorite apatite orthoclase quartz topaz corundum and diamond. Similarly to the measure of hardness or moh rating with wood floors the pei class rankings will list the level of durability of the different tile types. In order to make the moh s scale as utilizable common minerals will be assigned with numbers.
