Introduction The infrared emissivity of materials can be measured in a form of continuous spectrum accurately by the Fourier transforms infrared spectrometer (FTIR) [1] which is widely used in testing infrared emissivity.
However, the method of FTIR to test infrared emissivity of powder materials was limited in widely use, because the device was expensive, bulky and tedious.
Liang [2] etc designed a portable infrared emission performance testing devices of powder materials basing on the principle of heat transfer.
Test Results and Analysis 4.1 Samples and performance characterization Tourmaline is a kind of natural mineral materials with high infrared emission properties [8].

All the materials were mixed together and were stirred using hot plate magnetic stirrer at 80oC for 3 hour to yield a clear and homogeneous solution.
Heating process was applied to increase the reaction process between the materials in the solution.
The images also proved prepared ZnO materials in this research were within nanometer range (<100nm).

The following endodontic procedures benefit from the use of the microscope: • locating hidden canals that have been obstructed by calcifications and reduced in size; • removing materials such as solid obturation materials (silver points and carrier-based materials), posts or separated instruments; • removing canal obstructions; • assisting in access preparation to avoid unnecessary destruction of mineralized tissue, • repairing biological and iatrogenic perforations; • locating cracks and fractures that are neither visible to the naked eye nor palpable with an endodontic explorer; • facilitating all aspects of endodontic surgery, particularly in root-end resection and placement of retrofilling material.
Materials and Methods In the clinic of the Department of Endodontics, Faculty of Dentistry in Craiova, were examined a total of 31 extracted human second maxillary molars.
