For refractory materials, sintering is very important, whether it is natural raw materials, or synthetic raw materials, have to be burned, to sinter before use, fire-retardant refractory products is to achieve the date of sintering. Unshaped refractory materials in the process of gradually sintering. From a process point of view, sinter is a sturdy, low porosity (almost airless 7L) stone made from a powder at high temperatures. Refractories degree of flexibility of the signs, usually with the object size reduction (the so-called shrinkage), reduced porosity and bulk density increased to measure. Sintering is mainly due to the strengthening of refractory material, the inevitable result of increased contact between the particles. Sintering (intrinsic) has the following processes: changes in the shape of the pore size phase; crystal growth, residual stress (suppression) reduction and equilibrium; liquid phase formation; redistribution of phase space; In many cases, sintering accompanied by multi-phase transformation of certain phases, solid-phase chemical reactions or liquid-phase reactions. The reaction forms a new phase and a solid melt. The final cooling complicates the enumeration process, with some of the opposite processes occurring. Multi-product changes, melt crystallization and crystallization pressure may occur, the formation of the glass phase and other phenomena. Like the lower temperature drop, the refractory material produces stress and often produces macroscopic defects so that the refractory products are discarded. Temperature gradients, temperature change rates, phase and concentration gradients, atmospheres, high frequency field effects, vibrations and other conditions in a refractory body all depend on the temperature. Even within the refractory material. y1 its temperature changes have a very complex phenomenon, can not fully enumerate the occurrence of the process

With the development of the world automobile industry in recent years the technology on rearview mirror is also greatly improved, as demands a higher request on mold bricks in terms of its performance and quality. We have been working on the research and development. of Mold Bricks since 2000, and in March 2003 success was achieved in the trial manufacture, in Sep 2003 a Mold Brick production line was established, and we are now a factory specialized on Mold Brick for Viewing Mirrors. MD Mold Bricks characterize as follows: 1. Low permanent linear change on reheating Firing under the temperature of 1050 Degree. Ensures no distortion and no permanent linear change on the mold bricks. 2. High dense structure MD Mold Brick is manufactured from micron grade material, which is pressed molding following being mixed by high speed blender. The maximum rod is 1000 with extremely fine section structure. 3. Good Thermal Shock Stability. No cracks even chap would be happening after long service of the bricks 4. Easy to be machined The Mold Brick is manufactured based on the customer request, which avoids waste from cutting of the big blocks. We have established good fame among our customers since our mold brick line was put into production with some performances superior to similar products available in the market. MD mold bricks could also be used in thermal bending glass, thermal melting glass and art glass. We sincerely welcome the comments from all our customers.
