What does silicify mean?
Silicify means to convert something into silica or a silicate, or, when used intransitively, to become silica. The process is associated with geology, mineralogy, paleontology, chemistry, and the preservation of organic remains under heat, pressure, or chemical conditions. In paleontology, for example, silica can gradually replace the original material of shells, bones, or plant tissues, producing a mineralized fossil. The verb is relatively uncommon outside technical contexts, so ordinary writing often uses the plainer phrase “turn into silica” instead. Silicify is related in form and origin to silica, silicate, siliceous, and silicon. Its principal form is the noun silicification, which names the conversion process itself.
verbTo convert something into silica or a silicate, especially through a chemical or geological process. It can also be used intransitively to describe a substance becoming silica.
- To convert something into silica or a silicate, especially through heat, pressure, chemical reaction, or geological transformation.
- To become silica or a silicate.
"Extreme heat can silicify the remains of marine organisms."
"The process silicified the wood, preserving it as a mineralized fossil."
"Under prolonged heat and pressure, the sediment gradually silicified."
Silicify names the process that turns material into silica, the compound from which glass and many minerals are formed.

How silicify is actually used
This is a rare formal or scientific term used chiefly in geology, mineralogy, paleontology, chemistry, and materials science. In non-specialist writing, a more direct phrase such as “convert into silica” is usually clearer.
