Terbium (Tb): The Rare Earth Hidden Inside Optical Isolators

You may never have heard of terbium, but you have almost certainly seen its light: the green glow of fluorescent lamps, X-ray intensifying screens in hospitals and LCD backlights all come from the same rare-earth element.Within the rare-earth family, terbium stands out in two directions. One is light: it emits the green wavelengt…

99.999% High-Purity Calcium Oxide (Part II): From 1500°C Furnaces to Transparent Optical Windows

META DESCRIPTION99.999% high-purity calcium oxide (5N CaO) in CaZrO3 crucibles, hydrogen sensors, transparent spinel ceramics and red phosphors — where impurity control decides performance.KEYWORDShigh purity calcium oxide, 99.999% CaO, 5N calcium oxide, CaZrO3 crucible, titanium alloy melting, proton conductor, hydrogen sensor,…

99.999% High-Purity Calcium Oxide in Advanced Ceramics: MLCC Reliability, PTC Stability, 5G/6G Microwave Dielectrics & CCTO

In our previous article, we explained how 5N ultra-high-purity calcium oxide (CaO) plays a decisive role in crystal growth and optical coating by “cutting off impurities at the source.” When transition-metal impurities such as Fe, Cu and Co are compressed to below 10 ppm, CaO transforms from industrial lime into the purity corn…

99.999% High-Purity Magnesium Oxide: Breaking the Bottleneck of Core Piezoelectric Materials, Domestic Substitution Is Now Here

From 5G/6G communication filters and medical ultrasonic probes to vehicle-mounted sensors and aircraft vibration monitors, the core of these devices is piezoelectric ceramics or piezoelectric crystals. They convert tiny mechanical vibrations into precise electrical signals, or transform electric fields into mechanical deformation…

High-Purity Magnesium Oxide Enable the Transparency Miracle in Ceramics

A ceramic that is as transparent as glass, yet withstands extreme heat and high-velocity impacts? This isn’t science fiction – it’s transparent ceramic, one of the few advanced materials that combines optical clarity with mechanical toughness. The key ingredient behind this “transparency miracle” is high-purity magnesium oxi…

Industrial Breakthrough: How Chinese Scientists Used Furnace Scale to Solve High-Purity Magnesium Purification

Researchers from Xi’an Jiaotong University have developed a novel, low-cost method to remove aluminum impurities from magnesium — a long-standing challenge in the industry. The technique, inspired by everyday furnace scale, has already been deployed on industrial production lines.From 109.5 to 6.3 ppm: A Leap in Magnesium Purit…

Indium Price Rises Again! PV + AI Dual Drive Widen Supply-Demand Gap for Strategic Metal

According to the latest spot market data released by ccmn.cn on April 30, 2026, the average market price of domestic indium (In ≥ 99.995%) stood at 4,650 RMB/kg, with a price range of 4,600–4,700 RMB/kg, up 110 RMB from the previous trading day, a single-day increase of approximately 2.42%.Supply Side: A “Rigid Shortage” Unde…

Chinese Researchers Achieve New Progress in Strength-Plasticity Regulation of Magnesium Alloys

Chinese researchers have made new breakthroughs in tuning the strength and plasticity of magnesium alloys. As lightweight demands grow in aerospace, rail transportation, and electronics, magnesium alloys—among the lightest metal structural materials—face a common challenge: high strength often comes at the cost of low plasticit…
