In the wave of global competition and technological iteration, in order to help build a solid foundation for national industrial upgrading, it is always necessary for some enterprises to have extraordinary courage and outstanding innovative spirit to open up new paths and frontiers in front of technological barriers. Henan Tianma New Materials Co., Ltd. (hereinafter referred to as "Tianma New Materials"), a company that has always been committed to serving the country through industry, taking import substitution as its mission, and has been deeply engaged in the field of fine alumina for 25 years, is such a "pioneer". On this website of China Powder Industry, let's take a closer look at Tianma New Materials and see its remarkable achievements in the field of fine alumina, from filling the domestic gap to leading the international track.

Tianma New Materials was born in the year 2000, when China's industry urgently needed breakthroughs in core technologies. At that time, high-end alumina materials had long been monopolized by overseas markets, while this key material was the "industrial backbone" in fields such as electronics, power, and aerospace. Ms. Ma Shuyun, the leader of Tianma New Materials, has a deep understanding of the pain points in the industry's development. With "import substitution" as the initial intention, relying on ten years of experience in the development of special alumina in research institutions, she has launched a breakthrough in independent research and development, and has completed three leaps in succession.
1. First Leap Forward: Special Aluminum Oxide for Sealing CRT Color Picture Tubes, Supporting the Rise of Domestic Home Appliance Industry
In the 1990s, China's color TV industry was in a period of explosive consumption, upgrading from black and white TVs to color TVs, with strong demand for production capacity. However, at that time, about 80% of the core component CRT cathode ray tubes relied on imports, and the CRT sealing material - low melting point glass aluminum oxide powder - was firmly stuck in the throat. Only a few overseas companies could supply it, with long delivery times and high price limited supply, which greatly constrained the development of China's color TV industry. Until 2001, Tianma New Materials had the courage to risk everything and reached a cooperation agreement with Zhuhai Caizhu Company of Rainbow Group. After repeated experiments and adjustments, they successfully produced qualified aluminum oxide for cone sealing of color TV cathode ray tubes. Not only did they obtain invention patents, breaking foreign monopolies, but they also provided stable supply for nearly 10 years with cost advantages until the replacement of color TVs, making important contributions to the rise of the domestic home appliance industry.
2. Second leap: Special alumina for electronic ceramic cast substrates, supporting the invisible power of Shenzhou spacecraft
Aerospace technology is a symbol of comprehensive national strength and a "super engine" for technological innovation. In order to meet the stable operation of spacecraft under extreme working conditions, extremely stringent requirements have been put forward for aerospace materials. To this end, Tianma New Materials once again closely followed the development needs of the national aerospace industry. In 2002, it conquered the domestic production technology of the core material of high-end electronic ceramic substrates - special alumina for electronic ceramic cast substrates. The product was successfully applied to the chips of spacecraft launchers such as Shenzhou 5 and 6, ensuring the safety of the country in the high-tech field.

3. The third leap: fully blooming in the fields of thermal conductivity, grinding and polishing, optoelectronics, and electrical engineering
From 2004 to 2009, Tianma New Materials successively developed many high-end alumina powder products, including special alumina for grinding monocrystalline silicon wafers, high thermal conductivity spherical alumina, special alumina for TFT-LCD liquid crystal substrate glass, and alumina for ultra-high voltage in the high-voltage switch industry (1 million volts). Among them, the performance indicators of special alumina products for grinding monocrystalline silicon wafers have reached the international advanced level, replacing imports and being exclusively produced domestically; The special alumina for TFT-LCD liquid crystal substrate glass has provided strong support for the national 863 scientific research project undertaken by Rainbow Group; The aluminum oxide used for ultra-high voltage in the high-voltage switchgear industry (1 million volts) has made its own contribution to the West East power transmission in the 13th Five Year Plan, and the performance indicators of the castings made from it have reached the level of similar products in Japan .....

Faced with the rise of new energy, 5G, AI and other new quality productivity, Tianma New Materials is continuously exploring the "technological transformation" path to meet the demand for capacity expansion. It has created a fully automated intelligent manufacturing matrix from feeding, sintering, grinding, homogenization, drying to packaging, and was awarded the "National Green Factory" in 2024. Nowadays, with the leap towards sustainable intelligent manufacturing through technological leadership, Tianma New Materials has formed an annual production capacity of 100000 tons of special alumina, and based on this, has closely followed the hot topics of industrial development, opening a new round of industrial innovation.
1. Keeping up with the AI wave: conquering the "high ground" of HBM packaging materials
With the explosion of AI computing power, the heat dissipation and signal stability of high bandwidth storage (HBM) chips have become bottlenecks. Tianma New Materials' forward-looking layout of low - α spherical alumina reduces the content of radioactive elements uranium and thorium to 5ppb, reaching an international leading level, improving the heat dissipation efficiency of chips while minimizing signal interference. At present, the Low - α - ray spherical alumina powder has achieved phased results and has entered the transition stage from experimental testing to industrialization.
