GENEVA
GENEVA, Dec. 10 -- Mikayel Hamamchyan, Armenia, has developed the
method of manufacturing building brick. According to an abstract
posted by the World Intellectual Property Organization: "Dry compound
from clay, quartz sand, starch as binding addition agent is prepared,
20% of water solution of sodium hydroxide is added to it, the obtained
mixture is formed and exposed to bake for 1,5 hour under 960-1050
deg.C, at that, the ratio of quartz sand and clay is 2,33:1, and the
ratio of dry compound and solution of sodium hydroxide is 6,25: 1.
Thus, the method is simplified, the obtained bricks have low heat
transfer and low gravity, but are solid, cold, heat and
chemical-resistant." The invention carries International Patent
Publication No. WO/2009/146470 on Dec. 10. The original patent was
filed in Armenia under application No. PCT/AM2009/000001 on May 6,
