1864 Proc. Royal Soc. 1863–4 13 335 The liquidity of silicic acid is only affected by a change, which is permanent (namely, coagulation or pectization), by which the acid is converted into the gelatinous or pectous form, and loses its miscibility with water.

1876 W. A. Tilden Introd. Study Chem. Philos. iii. 20 The ultimate pectisation of liquid silicic acid and other colloids is preceded by a gradual thickening of the liquid.

1938 W. L. Kubiëna Micropedology iii. iv. 137 Relationships of variation (B) also were found in some lateritic soils where the effect of pectization could not be seen by microscopic investigation.

1943 L. W. Sharp Fund. of Cytol. iv. 46 A sol may become a gel (gelation, pectization), and the gel may again become a sol (solation, peptization).
