Technology Process of PYROPHYLLITE

There total 2 articles about PYROPHYLLITE which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

aluminum oxide (1333-84-2,1344-28-1) + silica gel (112926-00-8,7631-86-9) → pyrophyllite (12269-78-2)

Guidance literature:

In not given; heating of Al2O3 and SiO2 (>1:2);;

Reference yield:

kaolinite + potassium oxide → pyrophyllite (12269-78-2) + muscovite

Guidance literature:

In water; byproducts: hydralsite; High Pressure; hydrothermal treatment (50 MPa, 400°C, 480 or 1056 h, molar ratio K2O:kaolinite 10:90 or 50 MPa, 400°C, 1056 h molar ratio K2O:kaolinite 20:80); X-ray diffraction;

upstream raw materials:

aluminum oxide

silica gel
