Tittle:
A Chinese company is looking for vacuum sealing ceramics manufacturing technology with improved performance
Summary:
A Chinese large special ceramic manufacturing company is looking for sealing ceramic manufacturing technology with new energy and high performance.

They want to cooperate with partners through research cooperation agreement and technical cooperation agreement.
Description:
The company is engaged in research, development, and application of zirconia ceramics, alumina ceramics and talcum ceramics. Its main production includes new energy series ceramics, thermostat series ceramics and electric light source series ceramic products, which are widely used in automobile, household appliances, lamps, traffic track and other fields.
The company which established in 2010, is located in Loudi City, Hunan Province.

They are looking for sealing ceramic manufacturing technology with new energy and high performance.
(1) Achieve a breakthrough in matching dry pressing molding of Al2O3 ceramics and metallization.
A. make a breakthrough based on traditional 95% Al2O3 ceramics craft formula.
B. make a breakthrough in control ceramic grain size by dry pressing molding process
C. make a breakthrough in metallization formula design, sintering temperature design
(2)The products are functional vacuum sealing ceramics. In order to ensure that the folding strength and sealing strength conform national standards, the folding strength of ceramics need to reach 350Mpa and the sealing strength reaches 135Mpa. Therefore, the following difficulties need to be overcome in the dry pressing molding process and metallization process of ceramics:
A. On the basis of ensuring the grain size of the porcelain, the ceramics should be as compact as possible with small pores and low porosity without delamination or cracking;
B. Achieve breakthroughs in the selection and post-processing of raw materials such as metallization Mo and Mn to ensure the mutual penetration and the grain matching of the metallization layer and the ceramic matrix;
C. When dry pressing, the binder and other additives are as few as possible, and the fluidity of the powder in the closed space is also a problem in the pressing process.
D. When printing, it shall not only ensure good paste fluidity and surface smoothness, but also reduce the introduction amount of adhesive for paste and the subsequent degumming.

They want to cooperate with partners through research cooperation agreement and technical cooperation agreement.
Technical Specification or Expertise Sought:
(1) Study out the optimal proportion scheme of 95%Al2O3 ceramics suitable for vacuum sealing to improve the folding strength of the ceramics, increase the sealing strength of 95%Al2O3 ceramics to 135Mpa from traditional 90Mpa, and reduce the porosity and cracking of the ceramic matrix.
(2) Develop separate upper and lower molds and adjustable structure molds to achieve the uniform density of all parts during product pressing, and guarantee the smoothness of pressing and moulding of complex structure products. To reduce the cracking and delamination of vacuum seal ceramics and improve the product qualification rate.
(3) Study the paste additive formula suitable for Al2O3 ceramic printing, reduce the amount of additive in the preparation of metallization paste, improve the fluidity and uniformity of screen printing metal paste, and ensure that the metal powder is evenly coated on the ceramic surface.
(4) Develop the metallization formula suitable for vacuum sealing ceramic components made of dry pressing 95%Al2O3 ceramics, so that the ceramic matrix and metal layer glass will move smoothly when the metal is burned, which can guarantee the best match between dry pressing 95%Al2O3 ceramics and Mo Mn.
