As an innovative product for no slurry lapping, TDT consists of an organic binder and inorganic abrasive materials and has been widely applied in glass thinning process including mobile phone window glass, notebook computer, sapphire and optical crystal glass and other hard brittle materials.
The application of such materials mainly has the characteristics as following: (1) lubricating.
The service life of TDT was evaluated by the weight ratio (G-Ratio) of the total amount of the lapping glass to the reduction amount of abrasive materials.
Conclusions (1) 3M TDT abrasive pad is a product for fixed abrasive lapping and can be used in thinning process of flat glass such as mobile phone window glass, notebook computer, sapphire and optical crystal glass and other hard brittle materials

Literature Sources Review Sulfur and its oxides in the form of sulphate and sulphide minerals appear in the raw mixture composition of portland cement clinker with both main raw materials for clinker preparation (clay and carbonate ore) and added additives and fuel.
Methods and Materials To identify C3A formation inhibition reasons in high-sulfate clinker, raw mixtures were roasted, designed to produce typical portland cement clinker with modular characteristics of KN=0.92, n=2.3 and p=1.69.
To assess the proposed calculation effectiveness with an SO3 content of more than 2% with raw materials described in the methods and materials, the high-sulfate raw material mixture was calculated for the formation of calcium monoaluminate at the first stage using the (8) with modular characteristics KN = 1 and SD = 0.

Furthermore, it is a very promising material for the use in optical devices operating in the ultraviolet spectral region [7].
This result can be transferred to the etching performance of materials with a face-centered cubic structure, such as silicon, where the (111) is the etch-stop plane being equivalent to the (002) plane in a hexagonal wurtzite structure [16].

Thus the processing of these materials culminates in the production of a large quantity of substances (some aggressive to man and environment) that have no immediate application, which results in an interference in the balance process of ecosystems.
Characterization of waste as aggregate Casting sand • Specific mass = 2,60 Kg/L • Unit mass = 1,16 Kg/L • Content of powdery materials = 8,8 % Blast furnace slag • Specific mass = 2,43 Kg/L • Unit mass = 1,05 Kg/L • Content of powdery materials = 4,9 % Determining the adequate composition.
The trials were firstly done with the following materials: cement, blast furnace slag, casting sand, metakaolin, superplasticizer and medium sand.
