METHOD FOR PRODUCING HIGH-MODULUS LIQUID GLASS Russian patent published in 2014 - IPC C01B33/32 

FIELD: chemistry.

SUBSTANCE: method includes adding 15-25 wt % aerosil with particle size of 5-20 mcm to an alkali metal hydroxide with concentration of 1.5-4.0 wt % heated to 80-99°C, mixing using ultrasound with frequency of 15-45 kHz, homogenising and dispersing the solution by repeatedly passing the solution through a magnetic field with induction in the operating zone of 0.05-0.5 T and then cooling to room temperature.

EFFECT: high elasticity of the liquid glass, resistance thereof to salty water and salt fog.
