Chemical properties:

Orpiment is one of the arsenic sulfide minerals. Monoclinic crystal system, the crystals are short columnar and plate-shaped, and the aggregates are flake-shaped, rod-shaped, powdery or kidney-shaped with radial structure, etc. The color is lemon yellow (slightly green). The streaks are bright yellow. Grease luster to diamond luster. The flakes are transparent and flexible. Hardness 1.5~2, density 3.4~3.5g/cm3. Does not conduct electricity. When burned on charcoal, it is easy to melt and the flame will be blue, white smoke and smell of garlic. Easily soluble in potassium hydroxide and leaves no residue. Mainly produced in low-temperature hydrothermal deposits, often symbiotic with realgar, stibnite, marcasite, quartz, etc.

use:

The weather resistance and durability of titanium nickel yellow are better than rutile titanium dioxide. It can be used in coil steel coatings, automotive coatings, vehicle and aviation coatings, as well as coatings and plastics for signs and road signs. It is used for the excellent stability of titanium nickel yellow and can be used for high temperature resistant coatings applied at high temperatures, plastics injection molded at high temperatures and other heat resistant coatings. Titanium nickel yellow has good chemical stability and can be used in chemical plant equipment and wall coatings, cement coatings, latex coatings and acid-cured amino resin coatings. Titanium nickel yellow is non-toxic and can be used in toy coatings and toy plastics, food packaging plastics and printing inks for food cans. The main disadvantages of titanium nickel yellow are light color, low tinting power, much coarser particle size than titanium dioxide, and poor dispersion. It is not suitable to be used as a yellow pigment alone. It is mostly used as a yellow base and other organic yellow pigments for light color weather resistance. Exterior coatings.

production method:

After the hydrated titanium dioxide in the production of titanium dioxide by the sulfuric acid method is fully washed, it is sent to the beating tank, and nickel and antimony-containing compounds with sufficient activity are added in a certain proportion, as well as a treatment agent that can promote the transformation of the crystal form during calcination. Mix evenly at a certain concentration, and after filtration, the filter cake is sent to the rotary kiln and calcined at a temperature of about 1000°C to complete the lattice transformation. If the calcination temperature is too high, material sintering will occur and affect the performance of the finished product. Therefore, it can be processed differently according to different uses.
