Abstract

Abstract

In this paper, different K₂O-P₂O₅-ZnO salt treatment formulas were used to treat meta-titanic acid, and eligible rutile titanium dioxide was obtained after calcination. SCX value as the blue phase indicators, Z-Ave value as the ZS90 mean particle size and SEM mean particle size were detected. The linear correlation among them was analyzed by means of linear fitting and regression. The results show that as the correlation indicators, the Pearson correlation coefficients of Z-Ave value and SCX value, SEM mean particle size and SCX value are respectively −0.957 and −0.935. There is a negative linear correlation between the two particle size indicators and SCX value. The R-Sq value of the linear regression equation between SCX value and Z-Ave is 91.6%, while this value between SCX value and SEM mean particle size is 87.5%. The linear regression results show that the prediction effectiveness of the SCX value for Z-Ave value is slightly better than that for SEM mean particle size. Manufacturers can put the conventional monitoring index SCX value into the corresponding fitting equation to carry out statistical analysis and tracking of product particle size, and adjust the process technology accordingly.
