METHOD TO PRODUCE GLASS CERAMIC CELLULAR MATERIALS Russian patent published in 2012 - IPC C04B38/02 

FIELD: construction.

SUBSTANCE: method to manufacture glass ceramic cellular materials includes slurry preparation of a charge with introduction of a silicon carbide in it, charge dehydration with subsequent formation of stocks, drying of stocks, speed burning, sintering of stocks to form a single bar, heating of the bar prior to completion of the foaming process, subsequent cooling of the single foamed bar, its separation into blocks of the preset size, baking of blocks. The quantity of silcon carbide or wastes of items processing containing at least 25% SiC introduced into the charge makes 0.1-5.0%. Stocks are pressed with thickness from 10 to 60 mm, the lower and the side surfaces of dried stocks prior to baking are coated with a refractory engobe, and the foamed bar separation into blocks is carried out along the surfaces of the stocks plastering.

EFFECT: production of foamed ceramic materials with thickness of up to 200 mm with evenly closed finely porous structure along the entire volume of the material.
