QUÉ SIGNIFICA MOHS SCALE EN INGLÉS
Escala Mohs de dureza mineral
La escala Mohs de dureza mineral caracteriza la resistencia al rayado de varios minerales a través de la capacidad de un material más duro para rascar un material más blando. Fue creado en 1812 por el geólogo y mineralogista alemán Friedrich Mohs y es una de varias definiciones de dureza en la ciencia de los materiales, algunas de las cuales son más cuantitativas. Sin embargo, el método de comparar dureza al ver qué minerales pueden rayar visiblemente a otros es de gran antigüedad, habiendo sido mencionado por Teofrasto en su tratado On Stones, c. 300 AC, seguido por Plinio el Viejo en su Naturalis Historia, c. 77 DC. Mientras que facilita grandemente la identificación de minerales en el campo, la escala de Mohs no es conveniente apto calibrar con precisión la dureza de materiales industriales.
definición de Mohs scale en el diccionario inglés
La definición de la escala de Mohs en el diccionario es una escala para expresar la dureza de sólidos al compararlos con diez estándares que van desde el talco, con un valor de 1, hasta el diamante, con un valor de 10.
