What Are Silicon Barium Calcium Prices On November 4, 2026?

Silicon barium calcium held steady on November 4, 2026: the Si50-52 Ba13 Ca13 grade is quoted at 7400-7600 yuan per tonne and transacted at 7300-7500 yuan per tonne, cash, ex-works, tax inclusive, from Henan, with a dash in the change column on both lines. What follows sets out the two ranges, the composition the designation describes and the 100 yuan gap between them. The grade belongs to the silicon barium series.

Table 1. Silicon barium calcium prices, November 4, 2026

Scope: one grade, Si50-52 Ba13 Ca13, on a cash, ex-works, tax-inclusive basis from Henan, induction furnace.

Note: Prices are in yuan per metric tonne exactly as published, with no thousands separator added. Packing, particle size, delivery point within the province and impurity limits are not stated in the source, so none of them is filled in here.

Two lines are published and they are not two qualities: they are the offer and the concluded business for one grade on one basis. The quotation sits 100 yuan per tonne above the transaction at both ends, 7400 against 7300 and 7600 against 7500, and each range is 200 yuan wide, so the two run parallel rather than converging.

The designation reads as three elements: silicon at 50 to 52 percent, barium at 13 percent and calcium at 13 percent, which together run from 76 to 78 percent of the alloy, the balance being iron and residuals. That is why the buyer's first question is not the headline price but the assay behind it: a tonne at 52 carries two points more silicon than one at 50, and barium and calcium are minimums in the published sheets.

On the published record the answer has two parts, and they should be kept apart. The quotation is 7400-7600 yuan per tonne and the transaction is 7300-7500 yuan per tonne, both cash, ex-works, tax-inclusive, for Si50-52 Ba13 Ca13 from Henan.

• Quotation - 7400-7600 yuan per tonne, unchanged.
• Transaction - 7300-7500 yuan per tonne, unchanged.
• Gap between the two - 100 yuan per tonne at each end.
• Basis on both lines - cash, ex-works, tax inclusive; induction furnace.

The 100 yuan gap works out at about 1.3 percent of the quotation, 100 over 7400 at the lower end and 100 over 7600 at the upper. That is a narrow spread for a material priced in whole yuan, and it matters because the two figures are often quoted side by side as though they described the same transaction. They do not: one is an asking range and the other a concluded range.

No. Both lines are recorded with a dash in the change column for November 4, 2026, which means no movement against the previous reading. The quotation stands where it stood at 7400-7600, and the transaction stands where it stood at 7300-7500. The grade, the basis and the region are also unchanged, so this issue's record repeats the prior level rather than adding a new one.

A flat reading is worth stating plainly. No movement is reported, no earlier or later assessment is used here, and no direction is carried forward from it.

Table 2. Composition published for the Si50Ba13Ca13 designation, mass percent

Scope: limits published by two independent supplier specification sheets for the Si50Ba13Ca13 designation, compared element by element; no standard text for this alloy was available for this check.

Note: These are trade limits rather than standard limits. The sheets agree on the three elements the designation names and differ on carbon, sulphur and phosphorus. Confirm the specification sheet issued by the supplier for the lot.

The practical consequence is that Si50Ba13Ca13 names the three main elements and leaves the residuals open. A buyer who cares about sulphur, carbon or phosphorus has to have those limits on the supplier's own sheet, since the designation does not settle them and the two sheets differ by a factor of six on sulphur, 0.05 against 0.3.

Two further points belong with the composition. Silicon is quoted as a band, 50 to 52, while the sheets state a minimum, so a lot at the top carries two points more silicon than one at the bottom and the price sheet does not separate them. Barium and calcium are both minimums, so a certificate can exceed 13 on either.

How the three elements work together in the ladle is the subject of the calcium silicon barium page: barium lowers the vapour pressure of calcium so that calcium survives in the melt long enough to act, and silicon carries the bulk of the deoxidation. For pricing, what matters is that the three are bought as one addition rather than three alloys, so the grade carries a single price per tonne.

Table 3. Quotation VS Transaction, Si50Ba13Ca13, November 4, 2026

Scope: the two published ranges for one grade on one basis, compared end by end in yuan per tonne.

Note: Both ranges are as published for November 4, 2026; the widths, gaps and percentages are arithmetic on those figures. The source does not state what causes the gap between asking and concluded prices, and no cause is inferred here.

The useful reading is the uniformity. A 100 yuan gap holding at both ends of a 200 yuan range means the two lines are one market seen twice, once as an offer and once as a settled trade, so a price inside 7300-7600 is not out of line. The room to negotiate is the 100 yuan between the two levels.

Seven items carry most of the commercial risk on a silicon barium calcium lot, and none of them is settled by the price column.

• The full composition - carbon, sulphur and phosphorus are not named by the designation and the published sheets disagree on all three, so fix them on the supplier's own sheet.
• The assay basis - agree how the analysis is determined and who pays for a check on a disputed lot.
• Particle size - the price record states none, and lump, grit and briquette forms differ between producers.
• Packing - 1 tonne jumbo bags are the common form, with drums or smaller bags on request.
• Delivery basis - this record is ex-works from Henan, so establish who carries freight and where title and risk pass.
• Settlement - the record is cash, so an offer on acceptance terms is not the same price.
• Quantity and inspection - fix lot size, tolerance and inspection rights, and ask whether a split shipment would come from one heat.

The production route recorded here is an induction furnace, worth naming in a contract where the buyer's process is sensitive to residuals. Background on how the alloy is positioned in deoxidation is on the silicon barium alloy as a deoxidizer page.

Table 4. Silicon barium calcium price questions, November 4, 2026

• Si50-52 Ba13 Ca13 is quoted at 7400-7600 yuan per tonne and transacted at 7300-7500 yuan per tonne, both unchanged on November 4, 2026.
• Both lines are on one basis - cash, ex-works, tax inclusive, from Henan, induction furnace.
• The quotation stands 100 yuan per tonne above the transaction at each end, about 1.3 percent, and both ranges are 200 yuan wide.
• The designation guarantees silicon, barium and calcium; carbon, sulphur and phosphorus are left to the supplier's sheet, and two published sheets disagree on all three.
• No standard text was available for this alloy, so the composition table records trade sheets rather than standard limits.
