·Feldspar is one of the most important rock forming minerals in the earth s crust Potassium or sodium rich feldspar is widely used in ceramics enamel glass abrasives and other industrial sectors They have a hardness of a specific gravity of t/m³ and a melting point of 1185 1490°C Commonly associated minerals
The hardness of a mineral is a criterion of its resistance to crushing Which of the following is an example of a hard material talc b calcite c sapphire d feldspar Rittinger s Law States that the energy required for crushing is proportional to the new surface created a Rittinger s Law b Kick s Law c Bond Law d Energy Law
·magnetite granite feldspar and quartz were tested for hardness abrasion compressive strength and modulus of elasticity and the work index is estimated Hardness Test Th e Rockwell test measures hardness by using diamond cone indenter The indentation is measured after a lighter initial load is applied and after a heavier load is applied
·Grinding together quartz and feldspar grains in an agate mortar results in crushing the feldspar fraction due to its smaller hardness Later sieving of the grinded mixture enables simple separation of both fractions Then it is possible to save the feldspar fraction for later analyses instead of losing it as it occurs when using acid etching Also
·Young s modulus and hardness of quartz K feldspar and plagioclase decrease with an increase in the peak load and tend to be stable when the peak load reaches 5000 μN whereas Young s modulus and hardness of biotite at multiple peak loads are in variability and irregularity 2 Young s modulus and hardness of quartz plagioclase and
·Although the use of feldspar in PVC and other thermoplasts is reported in the literature its use in thermoplastics is limited due to its comparably high Mohs hardness of 6 7 Especially high filler loadings of coarser PSD feldspars and nepheline syenite are prohibitive due to their abrasive behavior
