Foreword

YS/T 514 "high titanium slag and rutile chemical analysis method" is divided into 10 parts. --- Part 1. Determination of titanium dioxide content of ammonium ferric sulfate titration; --- Part 2. Determination of total iron content of dichromate method; --- Part 3. Determination of sulfur content of high frequency infrared absorption method; --- Part 4. Determination of the amount of silica weighing method, the molybdenum blue spectrophotometric method; --- Part 5. aluminum oxide content - EDTA titration; --- Part 6. Determination of a manganese oxide content by flame atomic absorption spectrometry; --- Part 7. calcium oxide, magnesium oxide content - Flame atomic absorption spectrometry; --- Part 8. Determination of the amount of phosphorus antimony molybdenum blue spectrophotometric method; --- Part 9. calcium oxide, magnesium oxide, manganese oxide, phosphorus, chromium oxide and vanadium pentoxide content - Inductively coupled plasma Daughters emission spectrometry; --- Part 10. Determination of the amount of carbon frequency infrared absorption method. This section YS/T Part 4 514. The partial replacement of YS/T 514.7-2006 "high titanium slag and rutile - The gravimetric method for chemical analysis of the determination of silicon dioxide content." This portion of YS/T 514.7-2006 compared to the main changes are as follows. --- Increased molybdenum blue spectrophotometric method; --- Increasing the repeatability limit and quality assurance and control provisions. The non-ferrous metal part by the National Standardization Technical Committee and centralized. This section is responsible for drafting unit. Zunyi Titanium Co., Ltd., China Nonferrous Metals Industry Standards and Metrology Institute for Quality. Participated in the drafting of this section. Jinchuan Group Co., Ltd. Fushun Titanium. The main drafters of this part. He Xiongjie, Fan Yong, Zhaojin Kai, Yu Shengjie, Zhuang Jun, Ma Yuping. When this part of the measurement ranges overlap, the method of analysis for the arbitration. This part of the standard replaces the previous editions are. --- GB/T 4102.7-1983; --- YS/T 514.7-2006. High titanium slag and rutile chemical analysis Part 4.

1 Scope

YS/T 514 This part provides high titanium slag and rutile determination of the amount of silica. This section applies to high titanium slag and rutile in the determination of the amount of silica. Measuring range. 1.00% to 10.00%.

2 Method summary

Sample with sodium carbonate - sodium peroxide mixed flux melt, leaching with dilute acid, silicic acid heated to dehydration, washing the filter through after 1000 ℃ Burning precipitated silica. Then treated with hydrofluoric acid, the silicon tetrafluoride to silicon vaporized form is removed. Quality before and after treatment with hydrofluoric acid Difference calculation of the percentage of silica.

3 Reagents

Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity. 3.1 sodium carbonate - sodium peroxide mixed flux. 3 parts of anhydrous sodium carbonate and 2 parts of sodium peroxide mix. 3.2 hydrofluoric acid (ρ about 1.15g/mL). 3.3 nitric acid (ρ about 1.42g/mL). 3.4 HCl (1 + 1). 3.5 sulfate (1 + 1). 3.6 sulfate (5 + 1). 3.7 Hydrogen peroxide (1 + 9). 3.8 ammonium thiocyanate solution (50g/L). 3.9 washing solution. Pipette 45mL sulfuric acid (ρ about 1.84g/mL) was slowly added 950mL of water, and mix. After cooling peroxide was added 5mL Hydrogen (3.7), and mix.

4 Sample

4.1 Sample size should be less than 90μm. 4.2 Sample required in advance at 105 ℃ ~ 110 ℃ drying 2h, placed in a desiccator, cool to room temperature. Step 5 Analysis 5.1 Sample Weigh 0.5g sample, accurate to 0.0001g. 5.2 Determination of the number of Determination to do 3 parts of the sample parallel to the mean value. 5.3 blank test Along with sample blank test.
