Description
Technical field
The present invention relates to a kind of preparation method of inorganic materials, especially relate to a kind of preparation method of Portland clinker.
Background technology
In research during hydrated cementitious, in order to reduce unkownable factors as far as possible, usually with laboratory synthetic cement and grog simple ore thing as research object.Yet when synthesizing cement clinker mineral with the method for conventional high-temperature sintering reaction, desired reaction temperature height not only, and owing to usually adopt mineralizer etc. to reduce firing temperature or the Within Monominerals crystal that makes some crystal formation at room temperature can stable existence, can in cement clinker mineral, introduce other compositions.
In recent years, appearance along with various chemical processes, brought the revolution of cement clinker mineral synthetic method, they all attempt to overcome synthesis temperature height, the reaction shortcoming such as wayward of traditional solid-phase sintering method, make great efforts to have breakthrough at the aspect of performance of synthetic product.The chemical process of using aspect synthetic at the cement system mineral mainly contains: polymerization organic and inorganic synthesis method, hydrothermal synthesis method, combustion synthesis method and sol-gel method etc.Polymerization organic and inorganic synthesis method requires harshness for the polymer support that is adopted, hydrothermal synthesis method only is applicable to the synthetic silicate mineral, the Ca/Si=2 of especially Dicalcium Phosphate (Feed Grade), and control hydro-thermal synthetic product is difficulty relatively, and combustion synthesis method only is applicable to calcium aluminate and iron calcium aluminate.Sol-gel method is a kind of method of colloid chemistry, it uses liquid chemical reagent or colloidal sol to be raw material, metal alkoxide or inorganic salt are directly formed colloidal sol or form colloidal sol with fixed attention through separating through hydrolysis, make the solute polymeric gelization then, again organic composition is removed in gel drying, calcination, reached required inorganic materials at last.Preparation process comprises the preparation of colloidal sol, formation and gel drying and the heat treatment of gel.
Tradition adopts the synthetic cement clinker mineral of the method for high temperature sintering reaction.This method desired reaction temperature is higher than 1450 ℃; Reaction process is wayward, and free calcium oxide content is reduced to below 1%, needs just can finish through repeated multiple times grinding, powder compression and sintering; Because the simple ore thing crystal that usually adopts mineralizer (as cupric oxide, Calcium Fluoride (Fluorspan), calcium sulfate, phosphorus oxide, titanium oxide) to wait to reduce firing temperature or make some crystal formation at room temperature can stable existence, can in cement clinker mineral, introduce and remove the thing phase that designs the product.
