"I strengthen the bentonite clay nozzle by dipping the rammed nozzle in a $50\%$ sodium silicate solution and allow to dry in warm oven. Then dip in a strong solution of Calcium Chloride, again dry. Then another dip in $50 - 70\%$ sodium silicate and again air dryed in warm oven. A third silicate treatment can be done. This makes for a strong nozzle that doesn't erode unless the motor thrust is over about $\pu{150kN}$." My question is: What is going on here chemically? Is it crosslinking?
