- the above-mentioned synthetic and natural titanium-containing carriers can be used singly or in mixtures for the preparation.
- the used residues from the TiO 2 production can filter moist
- Filter cake or used as a powder can be used as a powder. Besides, these can be used as a powder. Besides, these can be used as a powder. Besides, these can be used as a powder.
- Residues sour, washed, unneutralized, partially neutralized or neutralized for the production of the additive according to the invention can be used.
- the additive according to the invention may contain, in addition to residues of TiO 2 production, further synthetic and / or natural titanium dioxide-containing materials selected from the materials listed below or mixtures thereof: Intermediate, domed and / or finished products from the production of titanium dioxide.
- the materials may originate from the production of titanium dioxide after the sulphate process as well as from the production of titanium dioxide by the chloride process.
- the intermediate and co-products may be withdrawn from the ongoing TiO 2 production;
- Residues from the chemical industry for example from TiO 2 -containing catalysts, in turn, for example, from DENOX catalysts or from papermaking (so-called Fangstoff).
- the additive according to the invention may contain further auxiliaries and / or additives, for example carbonaceous materials, reduction carbon and / or metal oxides, again for example iron oxides.
- the additive according to the invention can thus contain titanium dioxide-containing materials selected from titanium ores, titanium dioxide-rich slags, synthetic titanium dioxide-containing materials or a mixture of two or more of these materials in addition to the metal slags and the residues from TiO 2 production.

- the additive can be subjected to a temperature treatment, preferably a drying, particularly preferably a thermal treatment at temperatures between 100 ° and 1200 ° C.
- the aggregate according to the invention contains from 5 to 90, preferably from 10 to 85, particularly preferably from 20 to 85, very particularly preferably from 30 to 80,% by weight of TiO 2 (calculated from the total titer content).
- the aggregate according to the invention may have a particle size between 0 and 15 cm, preferably between> 0 to 10 cm, more preferably between> 0 to 8 cm and most preferably between> 0 to 5 cm, the upper limit being included in each case ,
- the aggregate according to the invention may in particular also have a fineness of> 0 to 100 mm, preferably> 0 to 10 mm and particularly preferably of> 0 to 3 mm, the upper limit being included in each case.
- slags are used according to the invention, which are formed in the extraction of metals from the raw materials used as non-metallic substances.
- These slags are composed of basic oxides oxidic mixtures, which arise in the metal extraction in the Erzverhüttung and have porous to massive properties.
- slag is used as a secondary raw material in construction as aggregate for base courses or as an additive for cement.
- non-metallic substances are referred to in the art as metal slags and ironworks slags.
- the metallurgical slags are the slags produced in the extraction of metals such as aluminum, chromium, copper, lead, etc. They are also known as aluminum, chrome, copper and lead varnishes.
- the metal slag used is preferably the so-called aluminum salt slag. In addition to Al 2 O 3 , this slag still contains considerable amounts of aluminum nitride. The proportion of aluminum nitride may be up to 30 wt .-% or more, depending on the process control and method. Due to the AIN content, it is generally not possible to utilize the aluminum salt slags because, on contact with air or water, AIN reacts to undesired ammonia gas. Methods are known for working up and recycling such Al salt slags.
- the salt slag is crushed, separated by classification of the metallic portion. Subsequently, the salt components are washed out with water and thereby the resulting ammonia gases are converted by process gas purification into aluminum sulfate. After filtering off the water-insoluble oxides and crystallization of the dissolved molten salt then arise products that can be used as a low-cost raw material for the production of cement clinker and mineral wool. Despite elaborate treatment, however, a residual amount of aluminum remains unreacted as AIN or as ammonia in the product, which continues to cause a significant smell of ammonia. Only by thermal treatment, in particular complete drying, can the ammonia volatilize. However, this process is very expensive and not economical. A further disadvantage of metalworks slags is generally seen in the fact that they react very alkaline and as a result the usability is usually considerably restricted.
- nitride in the inventive use has the advantage that after production of the additive according to the invention, for example, when introduced into metallurgical furnace, the yield for the formation and deposition of titanium nitride and titanium carbonitride or on Feuerfestenausmauerungen is significantly accelerated.
- the ironworks slags are blast furnace, steelworks and secondary metallurgical slags.
- steelworks slag a distinction is made according to the production process of the steel.

- slags according to the invention in particular steelworks slags such as LD slag or electric furnace slag can be used.
- steelworks slags such as LD slag or electric furnace slag.
- the ironworks slags thus contain SiO 2 , Al 2 O 3 , CaO and / or MgO as main constituents. In addition, they still contain iron oxide, free iron and metal oxides and hydroxides. Due to the mineralogical and chemical composition as well as the physical properties of these slags, further processing steps are usually required before the slags can be recycled.
- the steelworks slags always contain free oxides, in particular free lime (CaO); MgO-rich slags also contain it free MgO (Table 2).
- the constituents of a basic slag from a cupola furnace are in% by weight, for example: 1
- the free lime content in the steel slag may be up to 10% by weight or more. With MgO, the free fraction is 8 wt% or more. Depending on the lime content of the LD slags, these are suitable as road building materials (with low lime content) or can be processed into fertilizers. The steelworks slags are therefore very alkaline, which significantly limits the usability.
- Slags can be used singly or in mixture in the production of titanium-containing aggregates.
- the additive according to the invention can be prepared by mixing the titanium-containing residues from the production of titanium dioxide with the slags from the metal extraction.

- the degree of basicity B is an empirical quantity which, in its simplest form, is the
- Slag components eg MgO, Al 2 O 3
- the concept of slag basicity B therefore does not correspond to the chemical basicity.
- basic slags At a basicity greater than one is called basic slags and at a basicity of less than one of acidic
- Quantity addition to highly alkaline metal slags a neutral product can be obtained, which is ideal for the above applications.
- the otherwise disadvantageous alkaline property of slags is used to neutralize the acidic residues from the production of TiO 2 .
- the slag and residues from the production of TiO 2 can generally be mixed in amounts depending on their pH values to give a pH of the product around the neutral point.
- resulting product has so often a pH of 5 to 1 1, preferably 6 to 10.
- the grain size is in the above ranges.
