In a key supporting sector of the national economic system, an industrial revolution driven by titanium metal is quietly reshaping the development trajectory of China's chlor-alkali industry.

I. Titanium Materials Solve a Century-Old Dilemma in the Chlor-Alkali Industry

1. The ion-exchange membrane electrolyzers, core production equipment of the chlor-alkali industry, operate year-round under extreme conditions of strong acidity, high temperature, and severe corrosion. This "century-old dilemma" has long restricted the industrial development. In the past, the service life of traditional graphite electrodes was only 3 months, and frequent replacements pushed up production costs. Moreover, the mercury cell electrolysis process generated severe mercury pollution, which was incompatible with environmental protection requirements and became a major obstacle to the industry's transformation.

2. The application of titanium metal provides a key solution to this problem. Its outstanding corrosion resistance, high strength, and low thermal conductivity make it the optimal material choice for the anode mesh and cell body of electrolyzers.

II.Cost Breakthroughs in China's Titanium Industry Support Large-Scale Application?

1. High Costs

The large-scale application of titanium metal was once long constrained by high costs. In the 1990s, domestic titanium plates with a thickness of 1 mm were completely dependent on imports, with a unit price as high as 800 yuan per kilogram. The expensive price made many industries hesitant to adopt it, and the chlor-alkali industry also found it difficult to widely use titanium materials for equipment upgrading.
2. Removing the Cost Barrier

In 2005, China successfully broke through the technological bottlenecks in the entire industrial chain of the titanium industry, achieving independent control over core links from smelting to processing. This breakthrough directly drove a significant drop in the price of titanium materials, with the unit price of 1 mm thick titanium plates falling to 120 yuan per kilogram, completely removing the cost barrier for the large-scale application of titanium metal.
3. The Professional Titanium& Titanium Alloy Manufacturer in Baoji

Today, China's titanium industry has established a globally leading advantage. According to data from Titanium Home, China currently accounts for 60% of the world's total titanium material output, among which the proportion of titanium used in the chemical industry reaches 35%, making it one of the core application scenarios for titanium materials. Enterprises represented by Baoti Group have developed high-purity titanium alloy plates whose performance is fully in line with international standards, while the price is only 60% of that of imported products, significantly lowering the application threshold for downstream industries. In Baoji, known as "China's Titanium Valley", Baoji Ruihang ElaborateMaterial Technology Co., Ltd. is a professional manufacturer of titanium and titanium alloy materials integrating R&D, production, sales, and service. It mainly engages in the R&D, production, and sales of titanium and titanium alloy plates, bars, and special-shaped forgings.

It has the largest inventory of spot materials among private titanium alloy enterprises in Baoji. The monthly production capacity of the company's titanium and titanium alloy bars and wires is 600 tons, and the annual spot inventory of plates is more than 300 tons.

China has also achieved technological breakthroughs in the core coating field that determines the application effect of titanium materials. The rare earth modification technology developed by the Institute of Metal Research of the Chinese Academy of Sciences has extended the service life of titanium-based electrodes to 15 years and increased the current efficiency to 97.5%, further reducing the long-term operating costs of equipment. Exclusive information from Titanium Home shows that patents related to this technology have been deployed in more than 20 countries around the world, marking China's official transition from a past importer of titanium materials to a global technology exporter in the titanium industry.

This series of dual breakthroughs in cost and technology not only provides solid support for the large-scale application of titanium materials in downstream fields such as the chlor-alkali industry but also reshapes the competitive pattern of the global titanium industry chain, enabling China to gain more initiative in the field of key basic materials.

III. Titanium Materials Pave the Way for the "Zero-Carbon Factory" Vision in the Chlor-Alkali Industry

1.Against the backdrop of the in-depth advancement of the "dual carbon" strategy (carbon peaking and carbon neutrality), titanium metal is becoming a core driver for the chlor-alkali industry's transformation towards zero carbon. A leading domestic chlor-alkali enterprise has taken the lead in piloting an integrated project of "titanium-based electrolyzers + green electricity for alkali production". By using photovoltaic power to drive the operation of titanium-based electrolyzers, the project has directly reduced carbon emissions by 62%, providing a practical and implementable sample for low-carbon production in the industry.

Cutting-edge technological R&D is also making continuous breakthroughs. Currently, the three-dimensional porous titanium electrode under R&D, with its better structural design and material performance, is expected to further increase electrolysis efficiency by 5%. If this technology is applied industrially, it will further reduce green electricity consumption and accelerate the chlor-alkali industry's full entry into the "green electricity era".

2. The long service life of titanium materials also provides key support for the circular economy. From low-carbon transformation on the production side, to efficiency breakthroughs on the technology side, and then to resource recycling on the resource side, titanium materials are reshaping the green development path of the chlor-alkali industry from multiple dimensions, continuously narrowing the gap between reality and the "zero-carbon factory" vision.Baoji Ruihang Group is committed to the application of Ti-green metal, to reduce carbon emissions.

Material innovation is the core engine of industrial upgrading, and the rise of China's titanium metal industry is by no means accidental. The national strategic layout for key basic materials has provided directional guidance and resource support for the development of the titanium industry. In turn, the demand for green and efficient production from downstream industries such as chlor-alkali has promoted the continuous iteration and upgrading of titanium material technology, forming a positive cycle of "strategic guidance - market-driven - technological breakthrough".
