A crude oil recovery chemical fluid is described and claimed. This fluid has been shown to exhibit excellent resistance to salt and high temperatures. This crude oil recovery chemical fluid includes a silane compound, an aqueous silica sol having an average particle diameter of from about 3 nm to about 200 nm, two or more anionic surfactants, and one or more nonionic surfactants.

A method produces a basic zinc cyanurate powder, the amount of a portion thereof which remains in a sieve having a mesh size of 1,000 &#x3bc;m being less than 1 mass %. The method includes heating, at 30 to 300&#xb0; C., a powder-form mixture which is composed of zinc oxide, cyanuric acid, and water, which has a ratio by mole of zinc oxide to cyanuric acid of 2 to 3, and which has a water content of 9 to 18 mass %, in a closed or unclosed state.

Basic zinc cyanurate fine particles are produced by subjecting a mixed slurry to wet dispersion using a dispersion medium at a temperature in the range of 5 to 55&#xb0; C., the mixed slurry being formed by blending water, cyanuric acid, and at least one component selected from zinc oxide and basic zinc carbonate such that the cyanuric acid concentration is 0.1 to 10.0 mass % with respect to water.
