Effects of grinding of the feldspar in the sintering using

Oct 30, 2004· The anorthoclase feldspar transformation to anorthite and albite in the glazed matrix was carried out with samples which had been ground for 15–60 min. • The anorthoclase mechanically activated at 120 min grinding time indicates a major amount that is present as amorphous phase and the response in the sinter is a glazed matrix.

Feldspar Wikipedia

Feldspars (K Al Si 3 O 8 Na Al Si 3 O 8 Ca Al 2 Si 2 O 8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as

The effect of feldspar and kaolin on mechanical

Mar 18, 2013· Feldspar and kaolin was ball milled at 320 rpm for hours with the aid of a dry grinding agent. Both minerals were combined with inorganic salt namely sodium chloride as a grinding agent. The grinding agent and mineral were mixed at the ratio of 1:1. The application of such grinding agent led to effectively reduce the particle size in a short time.
