Tianjin Research Institute of Silicate (TRIS) limted compny was founded in 1958, involved in research and development of glass, ceramic, refractory materials, fibre, artificial crystal, heating elements, solid-state physics, special mechanical and electrical equipment, as well as special instruments.

TRIS is staffed with 82 persons, among them are 18 senior engineers, 26 engineers and 31 junior professionals.

Being one of institutes special for the research of inorganic and nonmetalic materials. TRIS is well equipped with equipment and instruments necessary for the research and production tasks. The six subordinate research departments focus respectively on the development of special glass, glass packing (orsealing), DMFmade (called EFG method in the U. S. A. ) artificial crysfal, technical ceramic, heating elements and synthetic materials.

Over three decaded of development, TRIS has passesed strog technical power for glass, ceramic, artificial crystal, special fibre and heating elements research tasks. Its research achievements and products have been put into application in the sectors of millitary defence, electronic, optical, chemical, petroleum semiconductor and light industries, and medical science as well. Among nearly 200 research projects undertaken by TRIS, twenty ones won the awards above the ministry and municiple levels, including the state awards, invention award and international exhihit diploma. In addition to this, TRIS has been granted and is applying for above ten of the patents.
