High-performance alumina powder and aluminum nitride powder are widely used in the electronics field, and are the most critical and basic raw materials for the manufacture of insulation and thermally conductive parts in the electronics industry.
For example, electronic ceramic substrates are widely used in the field of IC chip (integrated circuit) manufacturing. Electronic ceramic substrates fired from alumina powder and pottery clay assume the role of chip “base”.
In the field of 5G communications, it is important to ensure good heat dissipation. In this field, high-performance alumina powder is often used to make insulating and thermally conductive ceramic components, thermally conductive resins and other materials.
In addition, special alumina can also be used as a raw material for grinding monocrystalline silicon wafers. Special alumina is also found in insulation materials in the UHV field, automobile spark plugs, and high-end textile machinery related wear-resistant parts…
The “hidden champion” of China’s high-performance alumina powder industry
Before 2000, high-performance alumina and aluminum nitride powder materials for high-end applications in China had long been mainly dependent on imports.
Since 2000, HNTM Advanced Ceramic Technology Corporation has successively broken the foreign technology monopoly on key products in a number of special alumina fields.
In 2001, HNTM developed and produced special alumina for sealing CRT color TV tubes, breaking the monopoly of Japanese companies in China.
In 2002, the company successfully developed and commercialized the production of aluminum oxide for electronic ceramic tape-casting chip substrates, making the technology localized and applied to transmitter chips in the aerospace field.
In 2004, HNTM exclusively developed special alumina for the production of monocrystalline silicon wafer grinding, which successfully replaced imports.
In 2008, a special special alumina for the production of TFT-LCD liquid crystal substrate glass was developed to realize localization in this field.
At present, in China’s aerospace industry, the specialty alumina produced by HNTM accounts for about 80% of the market in this field.
HNTM is still the only supplier of high-performance alumina used in the polishing and polishing of monocrystalline silicon wafers. Has truly become the “hidden champion” in the specialty alumina powder industry.
Application of special alumina powder in the field of thermal conductivity of electronic components
HNTM main products:
Alumina for electronic ceramic chip substrates, alumina for monocrystalline silicon grinding and polishing, spherical alumina for 5G high thermal conductivity, aluminum nitride powder, alumina for coating lithium battery diaphragm
In 2018, HNTM and the Chinese Academy of Sciences jointly established an advanced ceramic materials research and development center.
